Abstract
The Grand Alliance, a consortium formed in May 1993 by AT&T, David Sarnoff Research Center, General Instrument Corp., Massachusetts Institute of Technology, Philips Electronics North America Corp., Thomson Consumer Electronics, and Zenith Electronics Corp., proposed the use of the eight-level, vestigial sideband (8-VSB) transmission subsystem for advanced television (ATV) broadcast service after extensive comparative testing of 8-VSB and 32-quadrature amplitude modulation (32-QAM) at the laboratories of the Advanced Television Test Center (ATTC) and CableLabs. The Advisory Committee on Advanced Television Service (ACATS), an all-industry committee originally formed in 1987 to assist the Federal Communications Commission (FCC) in establishing a new television service to replace the NTSC system currently in use, approved this VSB transmission subsystem recommendation as one component of the high-definition television (HDTV) system under development.
