在千呼万唤中,中国的数字电视地面传输标准——GB20600-2006《数字电视地面广播传输系统帧结构、信道编码和调制》,终于在2006年8月18日正式批准为强制性国家标准,并将于2007年8月1日起实施。从2001年征集数字电视地面传输方案开始,数字电视地面传输标准的出台经历了长达5年的研究、测试和讨论。如果从1994年国家科委启动高清晰度电视项目开始算起,那这一过程则足足用了12年的时间。
In the long-awaited, China’s digital terrestrial television transmission standards - GB20600-2006 “digital terrestrial television transmission system frame structure, channel coding and modulation,” and finally on August 18, 2006 was formally approved as a mandatory national standard , And will come into effect on August 1, 2007. From the 2001 solicitation of terrestrial digital television transmission program began, the introduction of digital television terrestrial transmission standard has gone through up to 5 years of research, testing and discussion. If starting from 1994, the State Science and Technology Commission started HDTV project, then this process is fully spent 12 years.
