High-definition television

It has been suggested that High Definition Video be merged into this article or section. (Discuss)

High-definition television (HDTV) means broadcast of television signals with a higher resolution than traditional formats (NTSC, SÉCAM, PAL) allow. Except for early analog formats in Europe and Japan, HDTV is broadcast digitally, and therefore its introduction sometimes coincides with the introduction of digital television (DTV).

Historically, the term high-definition television was also used to refer to television standards developed in the 1930s to replace the early experimental systems, although, not so long afterwards, Philo T. Farnsworth, John Logie Baird and Vladimir Zworkin had each developed competing TV systems but resolution was not the issue that separated their substantially different technologies. It was patent interference lawsuits and deployment issues given the tumultuous financial climate of the late 20's and 30's. Most patents were expiring by the end of World War II leaving the market wide open and no worldwide standard for television agreed upon. The world used analog PAL, NTSC, SECAM and other standards for over half a century.

The terms HD ready and HD compatible are being used around the industrial world for marketing purposes. They indicate that a TV or display is able to accept video over an HDMI connection, using a new connector design, the main purpose of which seems to be to ensure that digital video is only passed over an interface which, by agreement, incorporates copyright protection. Even HD-ready sets do not necessarily have enough pixels to display video to the 1080-line (1920x1080) or 720-line (1280x720) HD standards in full resolution without interpolation, and HD-compatible sets are often just standard-definition sets with an HDMI input. This is a confusing use of the terms HD and HDTV.

Notation

In the context of HDTV, the formats of the broadcasts are referred to using a notation describing:

  • The number of lines in the display resolution.
  • Progressive frames (p) or interlaced fields (i).
  • Number of frames or fields per second.

For example, the format 720p60 is 1280 × 720 pixels, progressive encoding with 60 frames per second. The format 1080i50 is 1920 × 1080 pixels, interlaced encoding with 50 fields (25 frames) per second. Often the frame or field rate is left out. It can then usually be assumed to be either 50 or 60, except for 1080p which is only supported as 1080p24, 1080p25 or 1080p30 by consumer HDTV displays.

A frame or field rate can also be specified without a resolution. For example 24p means 24 progressive frames per second and 50i means 25 interlaced frames per second.

Most HDTV systems support some standard resolutions and frame or field rates. The most common are:

Standard resolutions

  • NTSC is typically 720x480

Standard frame or field rates

  • 24p (cinematic film)
  • 25p
  • 30p
  • 50p
  • 60p
  • 50i (PAL)
  • 60i (NTSC)

Comparison to SDTV

HDTV has at least twice the resolution of SDTV, thus allowing much more detail to be shown compared to analog television or regular DVD. In addition, the technical standards for broadcasting HDTV are also able to handle 16:9 aspect ratio pictures without using letterboxing, thus further increasing the effective resolution for such content.

Format considerations

The optimum format for a broadcast depends on the type of media used for the recording and the characteristics of the content. The field and frame rate should match the source, as should the resolution. On the other hand, a very high resolution may require more bandwidth than is available. The lossy compression that is used in all digital HDTV systems will then cause the picture to be distorted.

Photographic film destined for the theatre typically has a high resolution and is photographed at 24 frame/s. Depending on the available bandwidth and the amount of detail and movement in the picture, the optimum format for video transfer is thus either 720p24 or 1080p24. When shown on television in countries using PAL, film must be converted to 25 frames per second by speeding it up by 4%. In countries using the NTSC standard, (60 fps) a technique called 3:2 pulldown is used. One film frame is held for three video fields, (1/20 of a second) and then the next is held for two video fields (1/30 of a second) and then the process repeats, thus achieving the correct film rate with two film frames shown in 1/12 of a second. (See also: Telecine)

Older (pre-HDTV) recordings on video tape such as Betacam SP are often either in the form 480i60 or 576i50. These may be upconverted to a higher resolution format (720i), but removing the interlace to match the common 720p format may distort the picture or require filtering which actually reduces the resolution of the final output. (See also: Deinterlacing)

Noncinematic HDTV video recordings are recorded in either 720p or 1080i format. The format depends on the broadcast company if destined for television broadcast, however in other scenarios the format choice will vary depending on a variety of factors. In general, 720p is more appropriate for fast action as it uses progressive fields, as opposed to 1080i which uses interlaced fields and thus can have a degredation of image quality with fast motion. In addition, 720p is used more often with internet distribution of HD video, as all computer monitors are progressive, and most graphics cards do a sub-optimal job of de-interlacing video in real time. 720p Video also has lower storage and decoding requirements than 1080i or 1080p, and few people possess displays capable of displaying the 1920x1080 resolution without scaling. 720p appears at full resolution on a common 1280x1024 LCD, which can be found for under $250. An LCD capable of native 1080i resolution still costs over a thousand US dollars.

In North America, Fox, ABC, and ESPN (ABC and ESPN are both owned by Disney) currently broadcast 720p content. NBC, Universal-HD (both owned by General Electric), CBS, HBO-HD, INHD, HDNet and TNT currently broadcast 1080i content.

Technical details

MPEG-2 is most commonly used as the compression codec for digital HDTV broadcasts. Although MPEG-2 supports up to 4:2:2 YUV chroma subsampling and 10-bit quantization, HD broadcasts use 4:2:0 and 8-bit quantization to save bandwidth. Some broadcasters also plan to use MPEG-4. Some German broadcasters already use MPEG-4 together with DVB-S2 (ProSieben, Sat1 and Three Premiere Channels). Recommended receiver is Humax PR-HD 1000, but others are announced as well as PCI cards.

HDTV is capable of "theater-quality" audio because it uses the Dolby Digital (AC-3) format to support "5.1" surround sound.

The pixel aspect ratio of native HD signals is 1.0, or 1 pixel length = 1 pixel width. New HD compression and recording formats such as HDV use rectanglar pixels for more efficient compression and to open HDTV aquisition for the consumer market.

For more technical details see the articles on HDV, ATSC, DVB, and ISDB, respectively.

Advantages of HDTV expressed in non-engineering terms

  1. All commercial HD is digital, so the signal will either deliver a good picture, a picture with large pixelation, a series of frozen pictures, or no picture. You would never get a snowy, washed out, image, or vertical rolling.
  2. Most HD programming and films will be presented in the 16x9 proportioned, semi-widescreen format (though some films created in even wider ratios will still display "letterbox" bars on the top and bottom of even 16:9 sets.) Older films and programming that retain their 4:3 ratio display will be presented in a version of letterbox commonly called "pillar box", displaying bars on the right and left of 16:9 sets (rendering the term "fullscreen" a misnomer.) Or, one can usually choose to enlarge the image to fill the screen, however this option will display a distorted, stretched-out picture.
  3. The colors will generally look more realistic, due to the cleaner signal.
  4. The visual information is about 2-5 times more detailed overall. The gaps between scaning lines are smaller or gone.
  5. Two new pre-recorded disc formats will be available in spring 2006. One is called HD DVD, the other is Blu-ray. Both systems will usually play current DVDs, and attempt to extract a near-HDTV-quality image from them, but they are not compatible with each other.
  6. The increased clarity, and detail make larger screen sizes more comfortable and pleasing to watch.

Stereoscopic 3D television is far more practical with HD technology

A number of 3D stereoscopic major animation films like Polar Express, Disney's Chicken Little and 6 more scheduled for 2006 release, will be likely to be sold for home display in one or more of the new HD disk systems in 3D. The Discovery HD channel has already provided a small amount of science programing in 3D. Most professionals in 3D technology foresee greater use of stereo visuals and animation as HDTV becomes the norm.

Early systems

SECAM 755i

When Europe resumed TV transmissions after WWII, i.e. in the late-1940s and early-1950s, different countries used different resolutions. The UK used 405 lines, most other countries 625 lines (both numbers include the vertical gap, the actual resolution were lower), but France decided in 1948 to go for 819 lines. The French TV system thus became the world's first HDTV system, and, by today's standards, the French system could be called 755i (not all lines could be used for the actual image — some lines were lost during the vertical retrace). The French 819-line (or 755i) HDTV system was introduced in the 1950s. When, in the late-1960s, a second TV channel and color TV were introduced in Europe, the UK dropped its 405-line TV system (completely in 1985) and France dropped its 819-line system, making all European countries agree to use 625 lines (576i) for their TV transmissions.

The French "755i" 819-line HDTV system was used in only France, Belgium and Monaco, and in France only for the first French TV channel. It was discontinued in 1986. It was used only for black-and-white TV; color TV in 819-line SECAM never went beyond the experimental stage. It was transmitted only on VHF channels, and a French 819-line TV channel occupied 14 MHz of bandwidth.

MUSE

Japan has the earliest working HDTV system still in use, with design efforts going back to 1979. Japan began broadcasting analog HDTV signals in the early 1990s using an interlaced resolution of 1035 lines (1035i). The Japanese MUSE system, developed by NHK Science and Technical Research Laboratories (STRL) in the 1980s, employed filtering tricks to reduce the original source signal to decrease bandwidth utilization.

MUSE in Operation

  • In the typical setup, three picture elements on a line were actually derived from three separate scans. Moving images were thus blurred in a manner similar to using 16mm movie film for HDTV projection.
  • Stationary images were transmitted at full resolution.
  • Whole-camera pans would result in a loss of 50% of horizontal resolution.
  • Considering the technological limitations of the time, MUSE was a very cleverly-designed analog system.
  • MUSE had a bit-reduced stereo audio transmission system that was notable in its design as it was not psychoacoustical like Musicam.

Though Japan has since switched to a digital HDTV system based on ISDB, the original MUSE-based BS Satellite channel 9 (NHK BS Hi-vision) is still being broadcast. It broadcasts the same programs as BS-digital channel 103, but will end sometime in 2007.

HD-MAC

The European Commission established a European standard for uncompressed digital HDTV in a 1986 directive (MAC). However, it never became popular among broadcasters. It was required that all high-powered satellite broadcasters use MAC from that year. Owing to the advance of technology and the launch of middle-powered satellites by SES Astra, broadcasters could avoid MAC, and lower transmission costs. HD-MAC (the high-definition variant of MAC) was left for transcontinental satellite links, however.

Another reason for HD-MAC's failure is that it was not realistic to use 36 MHz for a high-definition signal in terrestrial broadcasting (SDTV uses 6-, 7- (VHF), or 8-MHz (UHF)). HD-MAC could be used only by cable and satellite providers, where there is a wider bandwidth available. Thus, analogue HDTV could not replace conventional SDTV (terrestrial) PAL/SECAM, making HD-MAC sets unattractive to potential consumers.

The HD-MAC standard was abandoned in 1993, and since then all EU and EBU efforts have focused on the DVB system (Digital Video Broadcasting), which allows both SDTV and HDTV.

Contemporary systems

Australia

Australia started HD broadcasting in January 2001, but only in August 2003 was HD content mandated. Most cities in Australia that have a population of 40,000 or greater have at least one terrestrial DTV channel available (for example, Albany, Western Australia, has had DTV available for almost a year as of May, 2005). However, most Australian DTV broadcasters are still experimenting with HDTV transmission and DTV delivery.

Brazil

Brazilian universities, research and government institutions are discussing the best policies for a digital television system for use in Brazil.

A complete testbed is expected for 2006 (see http://sbtvd.cpqd.com.br/ for updates).

Canada

In Canada, on November 22, 2003, CBC had their first broadcast in HD, in the form of the Heritage Classic outdoor NHL game between the Edmonton Oilers and the Montreal Canadiens. Bell ExpressVu, a Canadian satellite company, Rogers Cable and Videotron provide somewhat more than 21 HDTV channels to their subscribers including TSN HD, SportsNet HD, Discovery HD (Canadian Edition), The Movie Network HD, and several U.S. stations plus some PBS feeds and a couple of pay-TV movie channels. CTV Toronto broadcast in HD along with its western counterpart, BC CTV. They were also the first to broadcast a terrestrial HD digital ATSC signal in Canada. Global joined the crowd in late-2004. Other networks are continuing to announce availability of HD signals. CHUM Limited's Citytv in Toronto was the first HDTV broadcaster in Canada, however very few shows are shown in HDTV beyond the well-known ones such as CSI, ER, etc. as of early-2005. CBC officially launched HDTV programming on March 5, 2005.

Europe

Commercial HDTV services began in 2004 with Euro1080, an Belgian MPEG2/DVB-S pay channel. As for 2006, there has been a slow but steady increase in the number of HD channels available to european viewers in many countries. Although most of these channesl are pay tv, there are some free to air hd stations available(Prosieben & Sat 1), as well as technical transmissions by satellite.

A label "HD-ready" has been created to inform consumers of the benefits of High Definition. The purpose of the label is create a single norm to simplify the purchase of a HDTV in Europe.

Japan

Japan had pioneered HDTV for decades with an analog implementation. The old system is not compatible with the new digital standards. Japan terrestrial broadcast of HD via ISDB-T started in December 2003. It is reported that two million HD receivers have been sold in Japan already.

Republic of Korea

After a long controversy between the government and broadcasters, ATSC was chosen over DVB-T. From 2005, digital services are available in all the country.

It is required that at least 10 hours of HD content to be broadcast on a weekly basis during the first year of commercial digital service.

Mexico

Mexican television company Televisa made experimental HDTV broadcasts in the early-1990s, in collaboration with Japan's NHK. Some events are now broadcast in high definition.

During the first half of 2005, at least one cable provider in Mexico City (Cablevision) has begun to offer 5 HDTV channels to subscribers purchasing a digital video recorder (DVR).

In 2005, TV Azteca signed a deal with Harris Corporation's broadcast communications division for digital TV transmitters and HDTV encoding equipment to bring high-definition TV to nine Mexican cities.

The launch will be carried out in two phases. By the third quarter of 2006, HDTV transmissions will be available in Mexico City, Guadalajara and Monterrey. Phase Two of the national rollout will bring HDTV services to six additional cities (Matamoros, Reynosa, Nuevo Laredo, Ciudad Juarez, Mexicali and Tijuana) through the first half of 2006.

Also, TV Azteca has planned to broadcast the Mexican football tournament in HDTV. And one retailer, Elektra, started shipping televisions with HDTV receivers to support this broadcast.

XETV in Tijuana, Baja California - across the border from San Diego, California - is on the air in HDTV using 720p format. This affiliate of the American Fox TV Network is on UHF channel 23 broadcasting from Mt. San Antonio in Tijuana, Mexico with 403,000 watts, directed primarily northward at San Diego. In January 2006, Televisa's XEFB-TV and Multimedios' XHAW-TV in Monterrey, Nuevo Leon began HDTV transmissions on UHF channels 48 and 50, respectively.

Viewers with HDTV sets will receive picture resolution six times sharper than standard definition analog sets. Viewers without HDTV sets will continue to receive their television programming through analog transmission approaches.

United States

In the United States, HDTV specifications are defined by the ATSC. An HDTV-compatible TV usually uses a 16:9 aspect ratio display with an integrated ATSC tuner. Lower-resolution sources like regular DVDs may be upscaled to the native resolution of the TV.

Recording, compression, and prerecorded media

HDTV can be recorded to D-VHS (Data-VHS), W-VHS, to an HDTV-capable digital video recorder such as DirecTV's high-definition TiVo or Dish Network's DVR 921 or 942, or to a computer equipped with an HDTV capture card. In the U.S., the only current archival option is D-VHS. D-VHS digitally records a 28.2-Mbit stream onto a classic VHS tape, using a FireWire (IEEE 1394) digital transport to carry a compressed MPEG-2 Transport Stream from the tuning device to the recorder.

However, the massive amount of data storage required to archive uncompressed streams make it unlikely that an uncompressed storage option will appear in the consumer market soon. Realtime MPEG-2 compression of an uncompressed digital HDTV signal is also prohibitively expensive for the consumer market at this time, but should become inexpensive within several years (although this is more relevant for consumer HD camcorders than recording HDTV). Analog tape recorders with bandwidth capable of recording analog HD signals such as W-VHS recorders are no longer produced for the consumer market and are both expensive and scarce in the secondary market.

As part of the FCC's "plug and play" agreement, cable companies are required to provide customers that rent HD set-top boxes with a set-top box with "functional" Firewire (IEEE 1394) upon request. None of the DBS providers have offered this feature on any of their supported boxes. As of July 2004, boxes are not included in the FCC mandate. This content is protected by encryption known as 5C. This encryption can prevent someone from recording content at all or simply limit the number of copies.

Aside from scarce Japanese analog MUSE-encoded laser discs that are no longer produced, as of 2005 the only current available prerecorded HD media is D-Theater. Comprising less than 100 titles and utilizing a 28-Mbit/s MPEG2 stream at 720p or 1080i with either Dolby Digital 5.1 or DTS encoding, D-Theater is an encrypted D-VHS format, and only D-Theater capable D-VHS players can play back these tapes. This format is superior to broadcast HDTV due to its higher bandwidth and, of course, the ability to do non-realtime optimization of the encoding, which is not possible with broadcast HDTV. D-Theater is currently a small niche market even within the niche HDTV community, and it appears as if the final D-Theater title was published in 2004.

Future media

HD programming may be recorded on optical disc using Blu-ray or on HD DVD. Blu-ray technology is currently available only in Japan with a Japanese satellite/terrestrial tuner, but is expected to be released in other world markets in 2006. Blu-ray uses a blue-laser optical disc with an MPEG-2 or MPEG-4 codec. Sony will include a Blu-ray player in PlayStation 3, and it will be released during 2006. It is expected to have a big impact on the HDTV market.

Microsoft

In an attempt to provide a bitrate-compatible high-definition format for high-definition video on standard DVD-ROMs, Microsoft introduced their Windows Media 9 Series codec with the ability to compress a high-definition bitstream into the same space as a conventional NTSC bitstream (approximately 5 to 9 megabits per second for 720p and higher). Microsoft is marketing its high-definition Windows Media 9 Series codec as WMV HD. It remains to be seen if the codec will be adopted for widespread use, if only as a Wi-Fi industry standard. As of November 2003, this format required a significant amount of processing power to encode and decode and the only commercially-available movie that used the codec was the Terminator 2: Extreme Edition DVD (see 1). Since then, more titles have become available in this format, such as the acclaimed surf documentary Step Into Liquid. As of the start of 2005, Microsoft recommends a 3.0 GHz processor with 512 MB of RAM and a 128-MB video card for 1080p playback on Windows XP, though they are now commercially available DVD players, like the KiSS DP-600, that will play back WMV HD DVD ROMs in high definition on HDTV sets. The codec has been submitted to SMPTE and is in SMPTE's standardization process with an intent for it to become an official SMPTE standard known as VC-1 in the near-future.

Broadcasters

Other codecs are in contention such as AVC (MPEG-4 part 10, also known as H.264, approved by the ITU-T and MPEG standards bodies in early-2003) and the VP6 and now VP7 codecs from On2 Technologies.

H.264 as a standard has already been selected and adopted by the biggest broadcasters in the USA (DirecTV, DISH Network) and Europe (BSkyB, Premiere, Canal+, TPS, ...). H.264 was chosen for several reasons: The standard was validated as an open standard at least a year before VC-1 was seriously considered as a potential open standard, and, then, there is a lot of uncertainty on the levies Microsoft may want to impose once the algorithm is adopted. So far, only a handful of very minor broadcasters are seriously considering VC-1. It has been thought for a while that VC-1 was better adapted for the IPTV world than H.264, but press announcements have also already been made by some of the largest STB manufacturers like Amino, Pace, Kreatel demonstrating solutions based on H.264 standards.

The main areas of dominance of VC-1 seem currently to be in the Blu-Ray DVD (HD DVD have not yet announced support for VC-1) and, for obvious reason, the home PCs.

In fact, there is some concern in the community that Microsoft may have appropriated itself the H.264 standard, modified and improved upon it and are trying to resell the solution as VC-1, without providing dues to the MPEG-LA. However, this is currently a rumour and has not yet been challenged.

Example of broadcasters concerns.

Online HD

H.264 has made significant progress towards becoming a widespread video format on the internet thanks to Apple Computer's QuickTime software supporting the format as of version 7. Since many movie trailers are released in QuickTime format, when movie distributors started releasing HD trailers on the web the format they chose was H.264. H.264 is also used by some for encoding video podcasts.

VP6

VP6 was reported by On2 to have been chosen by China for use in the Enhanced Versatile Disc (EVD) format initiative. As reported, this was a result of China's desire to avoid royalties on WM9 or AVC. As an advantage, VP6 would not require royalties on recorded media (although royalties would be charged for player devices at a similar cost as for other codecs). As China starts to dominate manufacturing of TV and DVD units, the country's choice of standards becomes more important for everyone. A low cost for the codec itself is not a significant advantage over DVD, however, as the standalone hardware players will be incompatible with standard DVD-Video unless the manufacturer pays the royalties for the technologies necessary to make the player DVD-compatible. Very few titles were made available in any market for this format, although it is presumed that many would be needed to drive purchase of incompatible players. It is unlikely any major U.S. studio will commit to movies in this format without some form of copy-protection, which is not yet specified. Soon after the announcement that VP6 would be used on EVD, negotiations between On2 and E-World (the consortium pushing EVD to become a standard) broke down. On2 filed multiple breach of contract claims for arbitration, but in March of 2005 the arbitrator ruled that E-World had not broken the contract and owed nothing to On2. It was unclear to On2 and the arbitrator whether the Chinese government ever approved the EVD proposal as a standard.

HD DVD and Blu-ray

Recently, the DVD Forum and the Blu-ray Disc Association failed to agree on standards for high-definition 12-cm discs. A format war is now very likely between the DVD Forum's HD DVD (formerly "Advanced Optical Disc") standard and the Blu-ray Disc Association's Blu-ray disc standard. Both sides of the HD disc camp are likely to leverage studio partners against each other through exclusive arrangements. As a result, this will likely lead to certain films becoming available only on one format. A possible outcome of a messy format war could be the emergence of combo players, as the physical disc sizes are identical. A more likely possibility is that the PlayStation 3 console (manufactured by Sony, the main advocate of Blu-ray discs) will gain a major lead in sales for Blu-ray players when it launches in 2006. The Blu-ray format has already gained a majority support from almost every major movie studio in the USA, while the HD DVD format has received support from a smaller consortium of companies, many of whom have also pledged support for Blu-ray anyway.

Although they disagree about physical format technology, both the HD DVD and Blu-ray factions have selected the same three video codecs to be mandatory in their designs: specifically, MPEG-2 Part 2, VC-1, and H.264.

There are now some DVD players that will output enhanced or high-definition signals from standard-definition DVDs. These players, however, are not considered to be true HD DVD players since they include only an integrated scaler to upconvert the standard-definition DVD video to high-definition video. This upconversion process can improve the perceived picture quality of standard-definition video. Some DVD manufacturers such as Philips are licensing the DivX codec in order to play 720p/1080i content recorded on standard consumer DVD-R discs.

HD cameras

The standard for consumer/prosumer HDTV acquisition is High-Definition Video (HDV). It records MPEG-2TS compressed HDTV video on standard DV media (DV or MiniDV cassette tape) and transfers it using Firewire. All major Camcorder vendors provide camcorders in this segment.

Broadcast-level HD cameras often record to hard-drives via a raw input/output or to tape or flash disks in formats that support higher bitrates than MiniDV cassettes such a DVCPro HD. Recording at 100 Mbits/s, it uses a better color compression method to give better color representation than a standard DV25 or MiniDV cassette and less compression artifacts.

The standard for consumer/prosumer HDTV acquisition is High-Definition Video (HDV). It has been reported that the Nintendo Revolution will also feature an IBM chip, like the Revolution's predecessor, Nintendo Gamecube. Some DVD manufacturers such as Philips are licensing the DivX codec in order to play 720p/1080i content recorded on standard consumer DVD-R discs. (Toshiba plans to use it on HD TVs). This upconversion process can improve the perceived picture quality of standard-definition video. Meanwhile, Sony's PlayStation 3 will feature the Cell, a new chip designed by IBM, Toshiba and Sony in a joint venture. These players, however, are not considered to be true HD DVD players since they include only an integrated scaler to upconvert the standard-definition DVD video to high-definition video. The new Xbox 360 contains IBM's new tri-core chipset, which at the request of Microsoft IBM was able to design and ramp up to production volumes in less than 24 months (albeit using contract manufacturing).

There are now some DVD players that will output enhanced or high-definition signals from standard-definition DVDs. IBM has also been developing processing chips for gaming consoles. Although they disagree about physical format technology, both the HD DVD and Blu-ray factions have selected the same three video codecs to be mandatory in their designs: specifically, MPEG-2 Part 2, VC-1, and H.264. Free software available at alphaWorks (IBM's showcase for emerging software technology):. The Blu-ray format has already gained a majority support from almost every major movie studio in the USA, while the HD DVD format has received support from a smaller consortium of companies, many of whom have also pledged support for Blu-ray anyway. The initial developments of this project include scroll mice and other input devices that sense the user's pulse, monitor his or her facial expressions, and the movement of his or her eyelids. A more likely possibility is that the PlayStation 3 console (manufactured by Sony, the main advocate of Blu-ray discs) will gain a major lead in sales for Blu-ray players when it launches in 2006. The technology aims to enable devices to recognize and use natural input, such as facial expressions.

A possible outcome of a messy format war could be the emergence of combo players, as the physical disc sizes are identical. BlueEyes is the name of a human recognition venture initiated by IBM to allow people to interact with computers in a more natural manner. As a result, this will likely lead to certain films becoming available only on one format. The company will retain the right to use certain IBM brand names for an initial period of five years. Both sides of the HD disc camp are likely to leverage studio partners against each other through exclusive arrangements. IBM will have a 19% stake in Lenovo, which will move its headquarters to New York State and appoint an IBM executive as its chief executive officer. A format war is now very likely between the DVD Forum's HD DVD (formerly "Advanced Optical Disc") standard and the Blu-ray Disc Association's Blu-ray disc standard. The deal was approved by the Committee on Foreign Investment in the United States in March 2005, and completed in May 2005.

Recently, the DVD Forum and the Blu-ray Disc Association failed to agree on standards for high-definition 12-cm discs. In 2004, IBM announced the proposed sale of its PC business to Chinese computer maker Lenovo, which is partially owned by the Chinese government, for USD650 million in cash and USD600 million in Lenovo stock. It was unclear to On2 and the arbitrator whether the Chinese government ever approved the EVD proposal as a standard. Since that loss, IBM has made major changes in its business activities, shifting its focus significantly away from components and hardware and towards software and services. On2 filed multiple breach of contract claims for arbitration, but in March of 2005 the arbitrator ruled that E-World had not broken the contract and owed nothing to On2. On January 19, 1993 IBM announced a USD4.97 billion loss for 1992, which was at that time the largest single-year corporate loss in United States history. Soon after the announcement that VP6 would be used on EVD, negotiations between On2 and E-World (the consortium pushing EVD to become a standard) broke down. Litigation continued until 1983, and had a significant impact on the company's practices.

studio will commit to movies in this format without some form of copy-protection, which is not yet specified. The suit alleged that IBM violated the Section 2 of the Sherman Act by monopolizing or attempting to monopolize the general purpose electronic digital computer system market, specifically computers designed primarily for business. It is unlikely any major U.S. IBM in the United States District Court for the Southern District of New York, on January 17, 1969. Very few titles were made available in any market for this format, although it is presumed that many would be needed to drive purchase of incompatible players. v. A low cost for the codec itself is not a significant advantage over DVD, however, as the standalone hardware players will be incompatible with standard DVD-Video unless the manufacturer pays the royalties for the technologies necessary to make the player DVD-compatible. Department of Justice, which filed a complaint for the case U.S.

As China starts to dominate manufacturing of TV and DVD units, the country's choice of standards becomes more important for everyone. IBM's success in the mid-1960s led to inquiries as to IBM antitrust violations by the U.S. As an advantage, VP6 would not require royalties on recorded media (although royalties would be charged for player devices at a similar cost as for other codecs). It was originally known as the IBM System/360 and, in far more modern 64-bit form, is now known as the IBM zSeries (often referred to as "IBM mainframes"). As reported, this was a result of China's desire to avoid royalties on WM9 or AVC. The IBM computer range that earned it its position in the market at that time is still growing today. VP6 was reported by On2 to have been chosen by China for use in the Enhanced Versatile Disc (EVD) format initiative. General Electric remains one of the world's largest companies, but no longer operates in the computer market.

H.264 is also used by some for encoding video podcasts. NCR and Honeywell dropped out of the general mainframe and mini sector and concentrated on lucrative niche markets. Since many movie trailers are released in QuickTime format, when movie distributors started releasing HD trailers on the web the format they chose was H.264. Most of those companies are now long gone as IBM competitors, except for Unisys, which is the result of multiple mergers that included UNIVAC and Burroughs. H.264 has made significant progress towards becoming a widespread video format on the internet thanks to Apple Computer's QuickTime software supporting the format as of version 7. When only Burroughs, Univac, NCR and Honeywell produced mainframes, a bit later, people talked of "IBM and the B.U.N.C.H.". Example of broadcasters concerns. People in this business would talk of "IBM and the seven dwarfs", given the much smaller size of the other companies or of their computer divisions.

However, this is currently a rumour and has not yet been challenged. IBM was the largest of the eight major computer companies (with UNIVAC, Burroughs, Scientific Data Systems, Control Data Corporation, General Electric, RCA and Honeywell) through most of the 1960s. In fact, there is some concern in the community that Microsoft may have appropriated itself the H.264 standard, modified and improved upon it and are trying to resell the solution as VC-1, without providing dues to the MPEG-LA. Crago), "we couldn't imagine where we could absorb two thousand programmers at IBM when this job would be over someday." IBM would use its experience designing massive, integrated real-time networks with SAGE to design its SABRE airline reservation system, which met with much success. The main areas of dominance of VC-1 seem currently to be in the Blu-Ray DVD (HD DVD have not yet announced support for VC-1) and, for obvious reason, the home PCs. IBM neglected, however, to gain an even more dominant role in the nascent industry by allowing the RAND Corporation to take over the job of programming the new computers, because, according to one project participant (Robert P. It has been thought for a while that VC-1 was better adapted for the IPTV world than H.264, but press announcements have also already been made by some of the largest STB manufacturers like Amino, Pace, Kreatel demonstrating solutions based on H.264 standards. More valuable to the company in the long run than the profits, however, was the access to cutting-edge research into digital computers being done under military auspices.

So far, only a handful of very minor broadcasters are seriously considering VC-1. IBM built fifty-six SAGE computers at the price of $30 million each, and at the peak of the project devoted more than 7,000 employees (20% of its then workforce) to the project. H.264 was chosen for several reasons: The standard was validated as an open standard at least a year before VC-1 was seriously considered as a potential open standard, and, then, there is a lot of uncertainty on the levies Microsoft may want to impose once the algorithm is adopted. Working on the SAGE anti-aircraft system, IBM gained access to crucial research being done at MIT, working on the first real-time, digital computer (which included many other advancements such as an integrated video display, magnetic core memory, light guns, the first effective algebraic computer language, analog-to-digital and digital-to-analog conversion techniques, digital data transmission over telephone lines, duplexing, multiprocessing, and networks). H.264 as a standard has already been selected and adopted by the biggest broadcasters in the USA (DirecTV, DISH Network) and Europe (BSkyB, Premiere, Canal+, TPS, ...). In the 1950s, IBM became a chief contractor for developing computers for the United States Air Force's automated defense systems. Other codecs are in contention such as AVC (MPEG-4 part 10, also known as H.264, approved by the ITU-T and MPEG standards bodies in early-2003) and the VP6 and now VP7 codecs from On2 Technologies. IBM contributed to the war effort by manufacturing the Browning Automatic Rifle and the M1 Carbine.

The codec has been submitted to SMPTE and is in SMPTE's standardization process with an intent for it to become an official SMPTE standard known as VC-1 in the near-future. The topic is explored in the 2003 documentary film The Corporation. As of the start of 2005, Microsoft recommends a 3.0 GHz processor with 512 MB of RAM and a 128-MB video card for 1080p playback on Windows XP, though they are now commercially available DVD players, like the KiSS DP-600, that will play back WMV HD DVD ROMs in high definition on HDTV sets. IBM has donated more than 10,000 pages of archived documents concerning Dehomag to Hohenheim University in Germany and New York University. Since then, more titles have become available in this format, such as the acclaimed surf documentary Step Into Liquid. As of 2004 IBM's possible complicity in the Holocaust is the subject of at least one unresolved lawsuit. As of November 2003, this format required a significant amount of processing power to encode and decode and the only commercially-available movie that used the codec was the Terminator 2: Extreme Edition DVD (see 1). The author has responded to these claims (archive link, was dead; history).

It remains to be seen if the codec will be adopted for widespread use, if only as a Wi-Fi industry standard. The credibility of Black's book has been questioned, as has its claim that the Holocaust would have been impossible without Dehomag's data processing systems. Microsoft is marketing its high-definition Windows Media 9 Series codec as WMV HD. Watson knew of the German regime's activities and was indifferent to any moral issues. In an attempt to provide a bitrate-compatible high-definition format for high-definition video on standard DVD-ROMs, Microsoft introduced their Windows Media 9 Series codec with the ability to compress a high-definition bitstream into the same space as a conventional NTSC bitstream (approximately 5 to 9 megabits per second for 720p and higher). In 2001 author Edwin Black published a book titled IBM and the Holocaust, which alleged that Thomas J. It is expected to have a big impact on the HDTV market. Dehomag was taken over by the Nazis in December 1941.

Sony will include a Blu-ray player in PlayStation 3, and it will be released during 2006. During World War II, IBM's German subsidiary Dehomag (a portmanteau formed from "Deutsche Hollerith Maschinen Gesellschaft mbH", translated as "German Hollerith Machine Company Ltd.") provided the Nazi regime with punch card machines. Blu-ray uses a blue-laser optical disc with an MPEG-2 or MPEG-4 codec. Over time CTR came to focus purely on the punched card business, and ceased its involvement in the other activities. Blu-ray technology is currently available only in Japan with a Japanese satellite/terrestrial tuner, but is expected to be released in other world markets in 2006. The companies that merged to form CTR manufactured a wide range of products, including employee time keeping systems, weighing scales, automatic meat slicers, and most importantly for the development of the computer, punched card equipment. HD programming may be recorded on optical disc using Blu-ray or on HD DVD. On February 14, 1924, CTR changed its name to International Business Machines Corporation.

D-Theater is currently a small niche market even within the niche HDTV community, and it appears as if the final D-Theater title was published in 2004. In 1917, the Computing-Tabulating-Recording Company entered the Canadian market under the name of International Business Machines Co., Limited. This format is superior to broadcast HDTV due to its higher bandwidth and, of course, the ability to do non-realtime optimization of the encoding, which is not possible with broadcast HDTV. Watson Sr., the founder of IBM, became General Manager of CTR in 1914 and President in 1915. Comprising less than 100 titles and utilizing a 28-Mbit/s MPEG2 stream at 720p or 1080i with either Dolby Digital 5.1 or DTS encoding, D-Theater is an encrypted D-VHS format, and only D-Theater capable D-VHS players can play back these tapes. Thomas J. Aside from scarce Japanese analog MUSE-encoded laser discs that are no longer produced, as of 2005 the only current available prerecorded HD media is D-Theater. The president of the Tabulating Machine Corporation at that time was Herman Hollerith, who had founded the company in 1896.

This encryption can prevent someone from recording content at all or simply limit the number of copies. This company was a merger of the Tabulating Machine Corporation, the Computing Scale Corporation and the International Time Recording Company. This content is protected by encryption known as 5C. It originated as the Computing Tabulating Recording (CTR) Corporation, which was incorporated on June 15, 1911 in Binghamton, New York. As of July 2004, boxes are not included in the FCC mandate. IBM's history dates back decades before the development of electronic computers – before that it developed punched card data processing equipment. None of the DBS providers have offered this feature on any of their supported boxes. This came just a few months after IBM announced its support of the National Geographic's Genographic Project.

As part of the FCC's "plug and play" agreement, cable companies are required to provide customers that rent HD set-top boxes with a set-top box with "functional" Firewire (IEEE 1394) upon request. On October 10, 2005, IBM became the first major company in the world to formally commit to not using genetic information in its employment decisions. Analog tape recorders with bandwidth capable of recording analog HD signals such as W-VHS recorders are no longer produced for the consumer market and are both expensive and scarce in the secondary market. There has also been a steadily increasing movement of labour to cheap offshore countries such as India. Realtime MPEG-2 compression of an uncompressed digital HDTV signal is also prohibitively expensive for the consumer market at this time, but should become inexpensive within several years (although this is more relevant for consumer HD camcorders than recording HDTV). eliminated approximately 700 positions. However, the massive amount of data storage required to archive uncompressed streams make it unlikely that an uncompressed storage option will appear in the consumer market soon. On June 8, 2005, IBM Canada Ltd.

D-VHS digitally records a 28.2-Mbit stream onto a classic VHS tape, using a FireWire (IEEE 1394) digital transport to carry a compressed MPEG-2 Transport Stream from the tuning device to the recorder. After posting weaker than expected revenues in the first quarter of 2005, IBM eliminated 14,500 positions from its workforce, predominantly in Europe. In the U.S., the only current archival option is D-VHS. In more recent years there have been a number of broad sweeping cuts to the workforce as IBM attempts to adapt to changing market conditions and a declining profit base. HDTV can be recorded to D-VHS (Data-VHS), W-VHS, to an HDTV-capable digital video recorder such as DirecTV's high-definition TiVo or Dish Network's DVR 921 or 942, or to a computer equipped with an HDTV capture card. Historically IBM has had a good reputation of long-term staff retention with few large scale layoffs. Lower-resolution sources like regular DVDs may be upscaled to the native resolution of the TV. IBM employees won the lawsuit and arrived at a partial settlement, although appeals are still underway.

An HDTV-compatible TV usually uses a 16:9 aspect ratio display with an integrated ATSC tuner. In the 1990s, two major pension program changes, including a conversion to a cash balance plan, resulted in an employee class action lawsuit alleging age discrimination. In the United States, HDTV specifications are defined by the ATSC. Alliance@IBM, part of the Communications Workers of America, is trying to organize IBM in the U.S. Viewers without HDTV sets will continue to receive their television programming through analog transmission approaches. The company has traditionally resisted labor union organizing, although unions represent some IBM workers outside the United States. Viewers with HDTV sets will receive picture resolution six times sharper than standard definition analog sets. IBM is the only technology company ranked in Working Mother Magazine's Top 10 for 2004.

In January 2006, Televisa's XEFB-TV and Multimedios' XHAW-TV in Monterrey, Nuevo Leon began HDTV transmissions on UHF channels 48 and 50, respectively. IBM's efforts to promote workforce diversity and equal opportunity date back at least to World War I, when the company hired disabled veterans. San Antonio in Tijuana, Mexico with 403,000 watts, directed primarily northward at San Diego. IBM. This affiliate of the American Fox TV Network is on UHF channel 23 broadcasting from Mt. IBM's open source involvement has not been trouble-free, however; see SCO v. XETV in Tijuana, Baja California - across the border from San Diego, California - is on the air in HDTV using 720p format. This includes over 300 Linux kernel developers.

And one retailer, Elektra, started shipping televisions with HDTV receivers to support this broadcast. The company invests billions of dollars in services and software based on Linux. Also, TV Azteca has planned to broadcast the Mexican football tournament in HDTV. IBM's culture has been recently influenced by the open source movement. Phase Two of the national rollout will bring HDTV services to six additional cities (Matamoros, Reynosa, Nuevo Laredo, Ciudad Juarez, Mexicali and Tijuana) through the first half of 2006. (For further information, see Harvard Business Review, December 2004, interview with IBM Chairman Sam Palmisano.). By the third quarter of 2006, HDTV transmissions will be available in Mexico City, Guadalajara and Monterrey. A new post-Jam Ratings event was developed to allow IBMers to select key ideas that support the values.

The launch will be carried out in two phases. This event was focused on finding actionable ideas to support implementation of the values identified previously. In 2005, TV Azteca signed a deal with Harris Corporation's broadcast communications division for digital TV transmitters and HDTV encoding equipment to bring high-definition TV to nine Mexican cities. In 2004, another Jam was conducted in which more than 52,000 employees exchanged best practices for 72 hours. During the first half of 2005, at least one cable provider in Mexico City (Cablevision) has begun to offer 5 HDTV channels to subscribers purchasing a digital video recorder (DVR). As a result of the 2003 Jam, the company values were updated to reflect three modern business, marketplace and employee views: "Dedication to every client's success", "Innovation that matters - for our company and for the world", "Trust and personal responsibility in all relationships". Some events are now broadcast in high definition. Jam technology includes sophisticated text analysis software (eClassifier) to mine online comments for themes, and Jams have now been used six times internally at IBM.

Mexican television company Televisa made experimental HDTV broadcasts in the early-1990s, in collaboration with Japan's NHK. In 2003, IBM embarked on an ambitious project to rewrite company values using its "Jam" technology -- Intranet-based online discussions on key business issues for a limited time, involving more than 50,000 employees over 3 days in this case. It is required that at least 10 hours of HD content to be broadcast on a weekly basis during the first year of commercial digital service. But by the 1990s, IBM relaxed these codes; the dress and behavior of its employees does not differ appreciably from that of their counterparts in large technology companies. From 2005, digital services are available in all the country. For most of the 20th century, a blue suit, white shirt and dark tie was the public uniform of IBM employees. After a long controversy between the government and broadcasters, ATSC was chosen over DVB-T. In addition, middle and top management would often be enlisted to give direct support to salesmen in the process of making sales to important customers.

It is reported that two million HD receivers have been sold in Japan already. Traditionally, many of its executives and general managers would be chosen from its sales force. Japan terrestrial broadcast of HD via ISDB-T started in December 2003. IBM has often been described as having a sales-centric or a sales-oriented business culture. The old system is not compatible with the new digital standards.
IBM conducted a study in 2004 to find out that the Wiki vandalism was fixed, on average, within five minutes. Japan had pioneered HDTV for decades with an analog implementation. Starting from the date of the acquisition, Lenovo is permitted five years' use of the IBM and Thinkpad trademarks.

The purpose of the label is create a single norm to simplify the purchase of a HDTV in Europe. IBM owns a significant stake (about 19%) in Lenovo. A label "HD-ready" has been created to inform consumers of the benefits of High Definition. As part of the agreement, Lenovo moved its headquarters to New York State. Although most of these channesl are pay tv, there are some free to air hd stations available(Prosieben & Sat 1), as well as technical transmissions by satellite. In 2005, IBM sold its PC division to China-based Lenovo. As for 2006, there has been a slow but steady increase in the number of HD channels available to european viewers in many countries. A 2003 Forbes article quotes the head of IBM Research, who suggested a $1 billion in profit just for the research staff; however, they probably generate the bulk of new inventions in the company.

Commercial HDTV services began in 2004 with Euro1080, an Belgian MPEG2/DVB-S pay channel. [4], [5]. CBC officially launched HDTV programming on March 5, 2005. Protection of the company's intellectual property has grown into a business in its own right, generating over $10 billion dollars [3] to the bottom line for the company during this period. as of early-2005. [2]. CHUM Limited's Citytv in Toronto was the first HDTV broadcaster in Canada, however very few shows are shown in HDTV beyond the well-known ones such as CSI, ER, etc. That thirteen-year period has resulted in over 31,000 patents for which IBM is the primary assignee.

Other networks are continuing to announce availability of HD signals. patents than any other company. Global joined the crowd in late-2004. In every year from 1993 until 2005, IBM has been granted significantly more U.S. They were also the first to broadcast a terrestrial HD digital ATSC signal in Canada. In recent years IBM has steadily increased its patent portfolio, which is valuable for cross-licensing with other companies. CTV Toronto broadcast in HD along with its western counterpart, BC CTV. This program will be implemented over the coming years.

stations plus some PBS feeds and a couple of pay-TV movie channels. In 2002, IBM announced the beginning of a $10 billion program to research and implement the infrastructure technology necessary to be able to provide supercomputer-level resources "on demand" to all businesses as a metered utility. Bell ExpressVu, a Canadian satellite company, Rogers Cable and Videotron provide somewhat more than 21 HDTV channels to their subscribers including TSN HD, SportsNet HD, Discovery HD (Canadian Edition), The Movie Network HD, and several U.S. . In Canada, on November 22, 2003, CBC had their first broadcast in HD, in the form of the Heritage Classic outdoor NHL game between the Edmonton Oilers and the Montreal Canadiens. In the USA, they have earned four Turing Awards, five National Medals of Technology, and five National Medals of Science, and outside the USA, many equivalents. A complete testbed is expected for 2006 (see http://sbtvd.cpqd.com.br/ for updates). IBM employees have won five Nobel Prizes.

Brazilian universities, research and government institutions are discussing the best policies for a digital television system for use in Brazil. IBM Research has eight laboratories, all located in the Northern Hemisphere, with five of those locations outside of the United States. However, most Australian DTV broadcasters are still experimenting with HDTV transmission and DTV delivery. That total includes about 350 Distinguished Engineers and 60 IBM Fellows, its most senior engineers. Most cities in Australia that have a population of 40,000 or greater have at least one terrestrial DTV channel available (for example, Albany, Western Australia, has had DTV available for almost a year as of May, 2005). The company is increasingly focused on business solution driven consulting, services and software, with emphasis also on high value chips and hardware technologies; as of 2005 it employs about 195,000 technical professionals. Australia started HD broadcasting in January 2001, but only in August 2003 was HD content mandated. The consulting arm was previously known as Monday.

See also: COUNCIL DIRECTIVE 92/38/EEC of 11 May 1992. In 2002 the company strengthened its business advisory capabilities by acquiring the consulting arm of professional services firm PricewaterhouseCoopers. The HD-MAC standard was abandoned in 1993, and since then all EU and EBU efforts have focused on the DVB system (Digital Video Broadcasting), which allows both SDTV and HDTV. Palmisano was elected CEO on January 29, 2002 after having led IBM's Global Services, and helping it to become a business with a $100 billion in backlog in 2004 [1]. Thus, analogue HDTV could not replace conventional SDTV (terrestrial) PAL/SECAM, making HD-MAC sets unattractive to potential consumers. Samuel J. HD-MAC could be used only by cable and satellite providers, where there is a wider bandwidth available. In recent years, services and consulting revenues have been larger than those from manufacturing.

Another reason for HD-MAC's failure is that it was not realistic to use 36 MHz for a high-definition signal in terrestrial broadcasting (SDTV uses 6-, 7- (VHF), or 8-MHz (UHF)). It has engineers and consultants in over 170 countries and development laboratories located all over the world, in all segments of computer science and information technology; some of them are pioneers in areas ranging from mainframe computers to nanotechnology. HD-MAC (the high-definition variant of MAC) was left for transcontinental satellite links, however. With over 330,000 employees worldwide and revenues of $96 billion annually (figures from 2003), IBM is the largest information technology company in the world, and one of the few with a continuous history dating back to the 19th century. Owing to the advance of technology and the launch of middle-powered satellites by SES Astra, broadcasters could avoid MAC, and lower transmission costs. The company manufactures and sells computer hardware, software, infrastructure services and consulting services. It was required that all high-powered satellite broadcasters use MAC from that year. International Business Machines Corporation (IBM, or colloquially, Big Blue) NYSE: IBM (incorporated June 15, 1911, in operation since 1888) is headquartered in Armonk, NY, USA.

However, it never became popular among broadcasters. [9]. The European Commission established a European standard for uncompressed digital HDTV in a 1986 directive (MAC). Unstructured Information Management Architecture (UIMA) SDK: A Java SDK that supports the implementation, composition, and deployment of applications working with unstructured information. It broadcasts the same programs as BS-digital channel 103, but will end sometime in 2007. FairUCE: A spam filter that stops spam by verifying sender identity instead of filtering content. Though Japan has since switched to a digital HDTV system based on ISDB, the original MUSE-based BS Satellite channel 9 (NHK BS Hi-vision) is still being broadcast. (This is an ETTK technology.).

The Japanese MUSE system, developed by NHK Science and Technical Research Laboratories (STRL) in the 1980s, employed filtering tricks to reduce the original source signal to decrease bandwidth utilization. Policy Management for Autonomic Computing: A policy-based autonomic management infrastructure that simplifies the automation of IT and business processes. Japan began broadcasting analog HDTV signals in the early 1990s using an interlaced resolution of 1035 lines (1035i). Database File Archive And Restoration Management: An application for archiving and restoring hard disk files whose file references are stored in a database. Japan has the earliest working HDTV system still in use, with design efforts going back to 1979. IBM Performance Simulator for Linux on POWER: A tool that provides users of Linux on Power a set of performance models for IBM's POWER processors. It was transmitted only on VHF channels, and a French 819-line TV channel occupied 14 MHz of bandwidth. [7] [8].

It was used only for black-and-white TV; color TV in 819-line SECAM never went beyond the experimental stage. Examples from Wikipedia. It was discontinued in 1986. History Flow Visualization Application: A tool for visualizing dynamic, evolving documents and the interactions of multiple collaborating authors. The French "755i" 819-line HDTV system was used in only France, Belgium and Monaco, and in France only for the first French TV channel. Flexible Internet Evaluation Report Architecture: A highly flexible architecture for the design, display, and reporting of Internet surveys. When, in the late-1960s, a second TV channel and color TV were introduced in Europe, the UK dropped its 405-line TV system (completely in 1985) and France dropped its 819-line system, making all European countries agree to use 625 lines (576i) for their TV transmissions. December, 2004 Lenovo acquires 90% interest in IBM Personal Systems Group, 10,000 employees and $9 billion in revenue.

The French 819-line (or 755i) HDTV system was introduced in the 1950s. IBM continues to develop storage systems, including Tape Backup, Storage software, Enterprise storage, etc. The French TV system thus became the world's first HDTV system, and, by today's standards, the French system could be called 755i (not all lines could be used for the actual image — some lines were lost during the vertical retrace). 2003 Hitachi Global Storage Technologies now provides many of the hardware storage devices formerly provided by IBM, including IBM Harddrives & The Microdrive. The UK used 405 lines, most other countries 625 lines (both numbers include the vertical gap, the actual resolution were lower), but France decided in 1948 to go for 819 lines. 1996 Celestica Electronic Manufacturing Services (EMS). in the late-1940s and early-1950s, different countries used different resolutions. IBM Printing Systems now competes with Lexmark.

When Europe resumed TV transmissions after WWII, i.e. Lexmark has sold its keyboard and typewriter businesses. Most professionals in 3D technology foresee greater use of stereo visuals and animation as HDTV becomes the norm. IBM Retained a 10% interest. The Discovery HD channel has already provided a small amount of science programing in 3D. 1991 Lexmark (keyboards, typewriters, and printers). A number of 3D stereoscopic major animation films like Polar Express, Disney's Chicken Little and 6 more scheduled for 2006 release, will be likely to be sold for home display in one or more of the new HD disk systems in 3D. Now Motient.

For more technical details see the articles on HDV, ATSC, DVB, and ISDB, respectively. ARDIS mobile packet network, a joint venture with Motorola. New HD compression and recording formats such as HDV use rectanglar pixels for more efficient compression and to open HDTV aquisition for the consumer market. AT&T Business Internet, formerly IBM Global Network, formerly Advantis (joint venture with Sears). The pixel aspect ratio of native HD signals is 1.0, or 1 pixel length = 1 pixel width. Prodigy, formerly a joint venture with Sears. HDTV is capable of "theater-quality" audio because it uses the Dolby Digital (AC-3) format to support "5.1" surround sound. Taligent, a joint software venture with Apple Computer.

Recommended receiver is Humax PR-HD 1000, but others are announced as well as PCI cards. 1958 Time Equipment Division is sold to the Simplex Time Recorder Company. Some German broadcasters already use MPEG-4 together with DVB-S2 (ProSieben, Sat1 and Three Premiere Channels). 1942 Ticketograph Division is sold to the National Postal Meter Company. Some broadcasters also plan to use MPEG-4. 1934 Dayton Scale Division is sold to the Hobart Manufacturing Company. Although MPEG-2 supports up to 4:2:2 YUV chroma subsampling and 10-bit quantization, HD broadcasts use 4:2:0 and 8-bit quantization to save bandwidth. January, Classic Blue.

MPEG-2 is most commonly used as the compression codec for digital HDTV broadcasts. 2006

    . NBC, Universal-HD (both owned by General Electric), CBS, HBO-HD, INHD, HDNet and TNT currently broadcast 1080i content. December, Micromuse for $865 million. In North America, Fox, ABC, and ESPN (ABC and ESPN are both owned by Disney) currently broadcast 720p content. December, Bowstreet. An LCD capable of native 1080i resolution still costs over a thousand US dollars. October, DataPower.

    720p appears at full resolution on a common 1280x1024 LCD, which can be found for under $250. August, DWL. 720p Video also has lower storage and decoding requirements than 1080i or 1080p, and few people possess displays capable of displaying the 1920x1080 resolution without scaling. July, PureEdge. In addition, 720p is used more often with internet distribution of HD video, as all computer monitors are progressive, and most graphics cards do a sub-optimal job of de-interlacing video in real time. May, Gluecode. In general, 720p is more appropriate for fast action as it uses progressive fields, as opposed to 1080i which uses interlaced fields and thus can have a degredation of image quality with fast motion. April, Ascential Software for approximately $1.1 billion in cash.

    The format depends on the broadcast company if destined for television broadcast, however in other scenarios the format choice will vary depending on a variety of factors. February, Corio crio for $211 million. Noncinematic HDTV video recordings are recorded in either 720p or 1080i format. 2005

      . (See also: Deinterlacing). October, Systemcorp. These may be upconverted to a higher resolution format (720i), but removing the interlace to match the common 720p format may distort the picture or require filtering which actually reduces the resolution of the final output. August, Venetica.

      Older (pre-HDTV) recordings on video tape such as Betacam SP are often either in the form 480i60 or 576i50. July, Cyanea Systems. (See also: Telecine). July, Alphablox. One film frame is held for three video fields, (1/20 of a second) and then the next is held for two video fields (1/30 of a second) and then the process repeats, thus achieving the correct film rate with two film frames shown in 1/12 of a second.

Subsequently they conceived the idea of a small, portable tool which was able to read, write, work and think, which eventually turned out to be their first "ThinkPad" notebook computer back in 1992. The colors will generally look more realistic, due to the cleaner signal. The "ThinkPad" name for its notebook computers was brought up after an IBM researcher went to a coffee break and took a notepad out which had the word "THINK" on it. Most HD programming and films will be presented in the 16x9 proportioned, semi-widescreen format (though some films created in even wider ratios will still display "letterbox" bars on the top and bottom of even 16:9 sets.) Older films and programming that retain their 4:3 ratio display will be presented in a version of letterbox commonly called "pillar box", displaying bars on the right and left of 16:9 sets (rendering the term "fullscreen" a misnomer.) Or, one can usually choose to enlarge the image to fill the screen, however this option will display a distorted, stretched-out picture. Some think that this bears a striking similarity to the name of the fictional computer "HAL" featured in the Arthur C Clarke book and film "2001, A Space Odyssey". You would never get a snowy, washed out, image, or vertical rolling. If you step backward one letter in the alphabet for each letter of "IBM" you will arrive at "HAL".

          All commercial HD is digital, so the signal will either deliver a good picture, a picture with large pixelation, a series of frozen pictures, or no picture. Patents). 60i (NTSC).

          Watson Sr. Thomas J. IBM began hiring women to work as professional systems service staff in 1935. The first black employee was hired in 1899 by the Computing Scale Corporation (as it was known at the time).

          The infamous Control-Alt-Delete keystroke (David Bradley, 2001: "I invented it, but it was Bill [Gates] that made it famous"), also invented at IBM, is still frequently used on PCs running the Microsoft Windows operating systems. IBM invented many of the core technologies used in all forms of computing, including the first hard disk drive and the Winchester hard disk drive, the cursor (on computer screens), Dynamic RAM (DRAM), the relational database, Thin Film recording heads, RISC architecture, and the floppy disk. Software Group groups its products into five brands: DB2 (information management), Rational (software development lifecycle), Lotus (collaboration), Tivoli (systems management and security) and WebSphere (application as well as data integration and middleware). IBM's Software Group, if it were a separate entity, would be the second largest software company in the world, behind only Microsoft in total revenue.
