MEASURED PERFORMANCE CHARACTERISTICS OF THE DIGITAL ATV SYSTEM FOR TERRESTRIAL BROADCASTING IN THE UNITED STATES

摘要

At ISBT '93, the laboratory test results on four digital advanced television (ATV) transmission systems were summarized. Since then, the seven companies which developed those systems have worked together as the "Grand Alliance" to combine the best elements from each of their systems, and with further improvements, to develop one digital high definition (HDTV) system. The design and description of this system was approved in December 1994, by the FCC Advisory Committee on Advanced Television Service. This system is being tested by the Advanced Television Test Center (ATTC) in the U.S. April-July 1995.
