Digital Video Interactive (DVI) was the first multimedia desktop video standard for IBM-compatible personal computers. It enabled full-screen, full motion video, as well as stereo audio, still images, and graphics to be presented on a DOS-based desktop computer. The scope of Digital Video Interactive encompasses a file format, including a digital container format, a number of video and audio compression formats, as well as hardware associated with the file format.〔(【引用サイトリンク】title=Intel DVI File Format Summary )〕 ==History==
Development of DVI was started around 1984 by Section 17 of The David Sarnoff Research Center Labs (DSRC) then responsible for the research and development activities of RCA. When General Electric purchased RCA in 1986, GE considered the DSRC redundant with its own labs, and sought a buyer. In 1988, GE sold the DSRC to SRI International,but sold the DVI technology separately to Intelcorporation.〔 DVI technology allowed full-screen, full motion digital video, as well as stereo audio, still images, and graphics to be presented on a DOS-based desktop computer. DVI content was usually distributed on CD-ROM discs, which in turn was decoded and displayed via specialized add-in card hardware installed in the computer. Audio and video files for DVI were among the first to use data compression, with audio content using ADPCM. DVI was the first technology of its kind for the desktop PC, and ushered in the multimedia revolution for PCs. DVI was announced at the second annual Microsoft CD-ROM conference in Seattle to a standing ovation in 1987. The excitement at the time stemmed from the fact that a CD-ROM drive of the era had a maximum data playback rate of ~1.2 Mbit/s, thought to be insufficient for good quality motion video. However, the DSRC team was able to extract motion video, stereo audio and still images from this relatively low data rate with good quality.
