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..."

April 1991 - AD-HDTV and ACTV at NAB 91

NAB 91 was the first public demonstration of simulated picture clips from the AD-HDTV system.  Advanced Compatible Television (ACTV) remained the primary focus of the ATRC

1991 NAB ACTV - ADTV

May - Sept 1991 - AD-HDTV enters the harware design phase.  It is a massive "moon shot" effort to design a prototype implementation for what was probably the most complex television system that had ever been conceived at the time

 

     May 10, 1991 - internal design review kickoff (Reitmeier) 

     May 20, 1991 - System Design Progress Report Presentation to Erich Geiger (Thomson) - (Raychauduri)

     June 17, 1991 - Approach for Digital Television on Cable systems (Reitmeier)

      Aug 24, 1991 - Mid-course corrections to AD-HDTV project plan  

     Sept 1991 - Prototype Hardware Racks Configuration  |  Rack Power Requirements  |  System Integration Plan

1992 AD-HDTV System Integration and Testing

April 1992 - AD-HDTV at NAB 92

NAB 92 unleashed a tremendously competitive set of booths and demosnstrations, as the competing proponent systems

Jan - June 1992 - AD-HDTV System Integration at Sarnoff Field Lab
