Feb 5, 1991 - ADTV Progress Report summarizes project accomplishments
​
"... During the past six months, the concept of digital HDTV has moved from a few small technology development activities to a major development program. Setting the stage for this transition were advances in both data compression and RF transmission that showed the basic feasibility of a digital approach. In RF transmission, two independent efforts (at Sarnoff and Thomson-LER) showed that data rates on the order of 20-30 Mbps could be transmitted in the 6 MHz broadcast channel. In data compression, independent computer simulations (at Sarnoff, Philips-Briarcliff, TCE-LA, TCE-Hannover, and Philips-Paris) showed that both DCT-based and SubBand-based compression approaches could achieve HDTV picture quality within the bit rate of the RF transmission. By August 1990, it became clear that digital was the right way to achieve HDTV..."
