(COMTEX) A: Sony DVD Chip Entering China A: Sony DVD Chip Entering China CHINA, August 12, AsiaPort -- Recently, DVD chips developed by Sony have been applied to DVD now and DVDs with such kind of chip will made its debut in China soon. The chip can read signal 1.5 times faster than other common DVD chips, and its playing speed is 2 times faster than others. Moreover, the chip is compatible to CD, VCD, super VCD, and DVD. At the same time, it has the same size of VCD chip and super VCD chips, easier for VCD manufacturers transferring to DVD production. -0- Copyright 1998 Alestron, Inc. 19990812: AsiaPort Daily News * end of story *

A little DTV history.......................... In all, five competing prototype DTV systems were built. The Sarnoff Reseach Center developed one of these systems, and later acted as the integration point for the Grand Alliance system which followed the competitive phase of the U.S. standards process. The process itself was managed by the Advisory Committee on Advanced Television Systems. Sarnoff was the design center for the interlaced Advanced Compatible Television System. Their partners in this effort were NBC, Thompson, and Philips, which joined forces as the Advanced Television Research Consortium. In his book "Defining Vision--The Battle for the Future of Television," Joel Brinkley describes the transformation of the Sarnoff Research Center, where much of the history of American television was written: "In July 1987, just five months after Welch had cast them off, General Electric sold the rest of RCA's Consumer Electronics Division to Thomson Consumer Electronics, a company wholly owned by the French government. Faceless bureaucrats in Paris, of all places, now held rights to the proud RCA name. In fact, however, very little had changed. Joseph Donahue, a longtime RCA executive, had been one of the RCA-GE officers who managed the Sarnoff Research Center. Thomson quickly hired Donahue, and Donahue hired the Sarnoff Center as Thomson's research labs in America. The names and faces were the same. But General Sarnoff's men had become employees, in essence, of a foreign government." AT&T partnered with Zenith to develop a progressive scan system; AT&T developed the compression technology while Zenith developed the 8VSB modulation system which allowed the taboo channels to be used with minimal interference with existing NTSC transmissions. General Instruments developed two systems. The DigiCipher system--which caused ATV to morph into DTV--was developed by GI in San Diego, led by WooPaik, an engineer who had workked on research in this area at MIT's Center for Advanced Television Systems (CATS). The DigiCipher system used interlaced scanning. To hedge their bets, GI partnered with MIT to develop a second progressive scan system; this effort was led by Jae Lim, who inherited control of CATS, from it's founder, Dr. William Schreiber. The fifth system was developed by Japan's NHK. As they had the only existing HDTV production system, the interlaced 1125/60 system, NHK believed they held the inside track; their analog transmission system Narrow Muse, was designed to fit in a single 6 MHz channel...but it was not digital. more....................... digitaltelevision.com
