6 December, "based on the AVS standard digital video encoding and broadcasting and receiving system" passed under the auspices of the Ministry of information industry of the expert group on identification, this indicates that China's independent development of audio and video standard AVS already built completed including program production, playout and ingest, and many other aspects of a complete digital video broadcast system, to ready the actual application. The system also includes a significant outcome — — implement encoder AE100, this marks the AVS standard completeness and reality get verification to practical key step forward. The system consists of joint source digital audio and video technology co., Ltd. and the Institute of computing technology, Chinese Academy of Sciences, Shanghai Institute of radio and television company Center joint finish. Experts, the system in the coding efficiency than traditional MPEG-2 2 ~ 3 times, while the consumption of computing resources on a reduced 30% to 50%. Reportedly, at present, digital audio and video products most MPEG-2 international standards. Because MPEG-2 is the completion of standards in 1994, over the past 10 years coding progress already made MPEG-2 encoding efficiency and quality become increasingly unsatisfactory, replace with the new standards are sooner or later. In order for our digital audio and video industry in the future no longer appear in 2002 DVD patent storm that passive situation, in the Ministry of information industry and with the support of the Ministry of science and technology, China in 2002 organized audio video coding standard working group, began the development of national audio video coding standard AVS and completed during the year 2004 to develop AVS1.0 video standards.

6 December morning, "based on the AVS (audio video coding) standard for digital video broadcasting-encoded broadcasting and receiving system" technology passed appraisal of Ministry of information industry, the AVS result for Army General Huang and his allies were greatly relieved. Previously, AVS has submitted a Ministry of information industry, for national reporting, can become national standards, technical expertise to become one of the key factors. Due to the AVS standard are including systems, video, audio, three main standards and conformance testing and supporting standards, it directly relates to digital TV, IPTV, and even 3G application-orientated business such as, leading authorities in determining the relevant standards very seriously. It is understood that the end of October, the Ministry of information industry, held in the Conference have discussed the AVS GB problem, but until now there has not been concluded. Yellow tie that previously it was called the AVS only a dead letter, but with this demonstration of a complete solution that includes encoding software, decoding software, transmission system, transcoding technology and Phoenix-core chip, that AVS is fully equipped with the commercial capacity of the actual system. AVS Johnny currently, AVS has gained nearly 70 patents, but it has just been published, the situation is not optimistic. At that time, the front had MPEG-2 MPEG-4, H.264 etc, and relatively mature standards. Which, in radio and television sector MPEG-2 applied for over a decade, H.264 is MPEG-4 and many video manufacturers, operators favor with, but also on all AVS is limited to the laboratory. The State encourages research and development of independent intellectual property rights and technology environment, AVS from ZTE, Huawei, Alcatel, TCL, Hisense, joined a group of enterprises, the development of the AVS brings financial and technical support. A lot of experts after three years of repeated testing, research and development, AVS in the coding efficiency than traditional MPEG-2 efficient two to three times, in the calculation of resource consumption, reduced 30%-50%. But at the system level, AVS or selected and MPEG-2 system compatible. Institute of computing Institute Assistant, joint source company Chairman sui lilac told the "communications industry newspaper reporters, historical accumulation of MPEG-2, making it the industry chain upstream equipment formed a certain scale effect; in the lower reaches of the receiving device, its key chips are followed MPEG-2 standards. This enormous industry inertia short time it is difficult to reverse. Therefore, in order to achieve a smooth transition in the design of the AVS, the introduction of compatible MPEG-2 instead of replace. One consequence of this is that AVS will benefit from lower royalties of comparative advantage and MPEG-2 compete. Currently, MPEG-2 standard each decoding equipment charges $ 2.5, AVS each only 1 Yuan, and on the join its system of content producers and operators are no longer subject to additional fees. Industry noted that the use of "AVS compatible + high performance + low patent fee" strategy, have great chances of winning.
