September 21, AVS Working Group on the relevant responsible person revealed that the major concern of domestic audio-video standard is not only likely to become carriers of IPTV standards, and, as an international standard has no obstacles in principle is expected next year.
ITU has been certified
That date, AVS Working Group held its 18th plenary meeting, at least 200 participants, almost all the members attended AVS Union.
At the meeting, AVS Working Group of the Secretary-General Huang AVS revealed in the latest developments in standards. He said that recently, AVS has received the International Telecommunication Union (ITU) certification, AVS will very likely become the international standard.
According to reports, June 9, meeting in Huangshan, AVS has set up two special working groups, a special working group is FG-IPTV Working Group in particular, the task is to participate in ITU-T's IPTV standard-setting, so AVS to enter ITU standard for IPTV.
July 12, ITU held in Geneva in the first meeting of IPTV,HeYun led by China, proposed by the AVS standard as one of IPTV in ITU. The rules of ITU-house experts, or the overall use of the standard others, AVS is the latter case.
Huang said, ITU reviewed more than two months after September 12 has been made to official documents, agreed to become their AVS and a.4 of a.5 Cooperation Organization, which means that AVS standards may have become directly adopted as the official ITU standard, that is a candidate standard.
MEPG4 out
"AVS has become international standards promulgated by ITU, no substantive obstacles," AVS Working Group, the original director of the Chinese Academy of Sciences calculated, it is digital media director of the Institute of Peking University Gaowen think so.
He said that as a candidate standard after this step, the remaining with the ITU is the process of IPTV in China by the MII to organize under the ITU; and one year after final approval is now the last between stages.
Previously, IPTV standards, there are two major foreign standards and domestic standards of AVS.
Huang sure that the future is very likely the same list with the AVS is Microsoft's VC1 and the industry's concern that the H264, and in terms of technical performance, MEPG4 because of technical performance is likely to be inappropriate will not be selected.
This is an unexpected choice. At present, China Radio, Film and Television audio and video technology is used MEPG2, as an upgraded version of MEPG2 original MEPG4 a loud voice, Radio Communication Systems are interested in adopting MEPG4, but not material may not be the surprise international standards.
"Some people say that the old support of the State Administration of Radio MEPG4, I have not been confirmed. SARFT in fact support the national standards, and now there are two national standards is, first, MEPG2; another is the recent promulgation of the AVS, news is that those who do not know where to come. MEPG2 defects and is obvious and can not deal with many new applications. ", Huang said the case also.
Commercialization of next year
Huang said that "the State Administration of Radio hope is to achieve the industrialization of AVS as soon as possible."
He also said the timetable for the industry: the end of this year in December; in June next year, with market conditions; listed in 2008. Have been awarded a special ground satellite frequency and conditions. This time the progress of the industrialization of TD-SCDMA faster than that.
On the importance of this process, AVS Working Group members of the core units, joint source cited, Chief Operating Officer, Zhang Weimin, a sad example: in one of the world's two major exhibition of the Netherlands Radio International Radio, Film and Television IPC Expo, the exhibition period a number of set-top box manufacturers in China have been forced move-out because there is no MEPG2 pay royalties after the Chinese set-top box manufacturers have begun to change its attitude, made a strong appeal to the promotion of standards.
Netcom in November will be set up outside the test network
Huang also revealed that the current process of industrialization of the concrete.
The Science and Technology Department of MII IPTV has presided over the trial in two phases, one phase of the laboratory has basically been done, and done in the MII, CATR, Internet interoperability testing has been no problem. And interoperability is the first important because carriers if there is no exchange between, there is no significance.
The second stage is in November, is to do Netcom network will be experimental, in a network of coastal cities. Huang also confirmed that Netcom's AVS-based IPTV standards enthusiasm, he said, AVS has recently established a special working group is the AVS video HeYun head of the Joint Working Group, including deputy head of China Netcom, Huawei's Bear get-together, TCL's Qin.
Progress on the product, he said that the basis of the current two-chip, such as Grand View has done a very professional, and head-end encoder manufacturers to source, on radio and television to start very early, and mature products has been launched.
AVS is not actually used for IPTV, in other areas, AVS has the actual business cases, 16 to cities and counties in Sichuan terrestrial transmission standard, the successful tenderer unit is a member unit of the League of Changhong. "AVS true is that industrialization projects of 703 projects in Sichuan Province, is digital television is concerned, I hope to create a model to fight it."
