DVI Technology Chronology
by Douglas Dixon
A chronology of the development of DVI Technology hardware and software,
which brought real-time interactive full-screen 30 fps motion video and audio to the PC platform --From the initial simulations at the David Sarnoff Research Center in 1983
to the first VDP chips and board set hardware in 1989,
productized in 1990 - 91 as the AVSS DOS software on the ActionMedia 750 & II boards,
with the i750 PA/DA and PB/DB Video Processor chips,
and as AVK software under Windows and OS/2 in 1992.

Early Simulations: 1982 - 1988
The development of DVI began in 1983 at the David Sarnoff Research Center (a.k.a. RCA Laboratories). RCA was acquired by General Electric in 1986. G.E. transferred the Sarnoff Labs to SRI International in February 1987, and then sold the DVI technology to Intel in November 1988. Almost all the original DVI Technology group also transferred from Sarnoff to Intel at that time. Intel moved the Princeton Operation to the Plainsboro building in June 1989. On Sept. 17, 1992 Intel announced the closing of the Princeton Operation, to merged into its facilities in Hillsboro, Oregon and Chandler, Arizona.
The technical development of DVI Technology begins with the initial concept and application simulations, then to first chips and boards, then the AVSS DOS software on the Pro750 and ActionMedia II boards with the i750 PA/DA and PB/DB Video Processor chips, then with the AVK software under Windows, OS/2, and finally under Video for Windows on the RT Video board with the scalable Indeo Video algorithm.
