An AVS based digital video broadcasting and receiving system passed a verification check on December 6, 2005. The development indicates that China has possessed a proprietary digital video broadcasting system, and Chinese TV stations can broadcast programs using coding and decoding systems and chips developed by Chinese scientists.
With the support of authorities concerned, Chinese scientists have developed the new generation AVS standards that attract the attention of more than a hundred domestic and overseas manufacturers and research institutes. More than 50 patents have been derived from the efforts, of which most are possessed by Chinese enterprises or research institutes.
The digital video broadcasting and receiving system is made up of front systems, covering program compressing (coding), program format conversion (converter), and program broadcasting control (broadcasting server). Compared to other compressing systems, the Chinese system can effectively raise the utility of channel resources, in addition to fending off intellectual property issues.
