Digital Video Interactive

Digital Video Interactive (DVI) was the first multimedia desktop video standard for IBM-compatible personal computers, developed around 1984 by Section 17 of The David Sarnoff Research Center Labs (a division of RCA at the time, later DSRC became a division of General Electric after their purchase of RCA in 1986, and then the technology was sold by GE to Intel in 1988). The DSRC was sold to SRI International and as of 2007, continues research operations in technology and other areas on a contract basis.

DVI technology allowed full-screen, full motion 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 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.
