Avs Audio And Video Standards Performed By Identification Of Striking Drama
About IPTV Standard protracted debate, and finally to the stage from the behind the scenes. December 13, by the China Communications Standards Association standards for IPTV in Beijing to begin the review process, including the three major domestic AVS, including audio and video codec standards will compete for IPTV Industry standards Dominance. 14, chaired by the Secretary from the Ministry of Science and Technology “based on digital audio and video Coding Standard (AVS) for digital video Broadcasting Encoded broadcast and receiving system “adopted in Beijing Expert Technical appraisal. This means that from a technical level, China has completed a digital video broadcasting system related to Frame.
Standard battle hint opportunities Thus, AVS to increase with MPEG 4 H.264 Two major international standards Competition Weight. I believe that domestic standards with international standards on the infighting, the industry, and even ordinary people should be able to understand. With the process of social development, human society experienced by the industrialized, post-industrial to Information The transition, while the company also gone from the production, Sell To the service of transformation, the current, it is proposed the “first-class standards of business sale” slogan. This argument may not be exact, after all, businesses can not fully living standard, the standard implicit Royalty After all, there is a limit to use, but from the TD-S CDMA And WCDMA, SCDMA, EVD And Blu-ray, HD DVD Competition, to the AVS close combat with the international standards, we can feel the standards behind the huge business opportunities.
Said that only high-definition Digital TV An area, its market capacity has reached 300 billion yuan, not to mention, this is only for standard applications such as the three major areas of AVS?? Digital TV, Network TV And one of the box. Accordingly, it is easy to imagine the intentions of the parties where the deadly struggle.
Years, China’s industries in the industrialization of the road trip all the more farther, but turned the history of industrial development and domestic industry-standard easy to find, hard to see. Because of this, domestic companies pay an annual amount of money to the multinational giant, the patent fees. AVS Working Group, said the Secretary-General Huang Tiejun, the next decade to provide enterprises with AVS decoder chip can save 1 billion U.S. dollars for the company’s real money. In fact, the yellow is just an overview of the Secretary-General of the forecast, the data very conservative. Prior to the application based on MPEG2 standard, a STB Or a built-in MPEG2 TV charges 2.5 dollars. When the MPEG4 and H.264 standard commercial, the only software and hardware to receive royalties, but also receive on-demand programming, it is clear, for each household, they should bear the cost base is much larger than 2.5 U.S. dollars on , also have to pay each month on a considerable amount of on-demand costs.
So that domestic standards with international standards AVS extreme PK, not only to several competing standards, which also mixed with the national interest, national sentiment and business interests. Because of this, many manufacturers have adopted the attitude, not only do not want to take risks, people really do not want to fall, be condemned by everyone, after all, the success of AVS standard, multi-country radio and television, and even influence the development of the telecommunications industry far.
AVS standard the advantage Present, AVS is not the main reason for the bullish market is one of its late start, so technology maturity and low level of industrialization, industry has not even complete. Because of this, the current field has taken the lead in the digital high-definition CCTV operations, it is operational by the decade-old MPEG2, China Telecom, China Netcom And Alcatel on the H.264 admire broadcasting system, Huawei And so tend to MPEG4. However, the industrialization of the problem, AVS Industry Alliance has a very profound understanding of the parties, and in all aspects of government support and efforts, this bottleneck should be very easy to be broken, when, AVS, relying on its low cost advantage, after all, lead high-end audio and video codec market. It can be said, because of AVS and H.264 MPEG4 walk in the back, so there is no historical burdens, and so there is no upgrade cost burden, its start at the beginning, we focus on high-end, forming a large Advantage of Backwardness.
1, compatible with multiple versions of the standard
It is because of a late start, the relevant departments and Organization In the development of AVS standard, full consideration of its market performance, and thus in the development process compatible with the MPEG family of standards, which compared with the MPEG4 and H.264 standards for a wider range of applications. Make a more discouraging for example, even if AVS standard does not become the dominant standard audio and video market, but the compatibility of the MPEG family of standards, will make its MPEG4 standard can be added, in the market place. From this level, as long as the AVS does not lag behind in technological standards, which become the dominant standard is more likely.
2, more advanced technology Published technical information on the current view, made AVS and MPEG, H.264 and better technical performance of the three which have not yet conclusive. However, in some areas, such as compression rate, according to Fan Jianping, deputy director of CAS Institute of Computing, said maintaining the same resolution in the case, AVS data compression rate is higher than international standards. As you know, for network television, the current bandwidth is needed to solve a problem, and therefore the bandwidth compression ratio and problem solving are closely related to the making AVS technically has the definite advantage.
3, patent fees are very low
For AVS is, there is a more crucial advantage is that compared to international standards, patents, lower cost. This article mentioned above, even if the MPEG2 Single Machine charging up to 2.5 dollars and MPEG4, and H.264 charges in this regard certainly be more so. In addition, these international standards have to charge the cost on demand programming. Obviously, AVS standard charge only one yuan for patent fees, with strong market competitiveness.
4, open source to promote the industrialization process
IT World Network has been the author published an article called “open source world to do Phoenix-core dance pioneer,” the article, the paper focuses on the AVS and the phoenix arising from the core advantages of open source. 15, Ministry of Information Industry Software and IC Promotion Center (SCIP) and the CAS Institute of Computing, IC Design Center in Ningbo in the Division on a formal contract Fung core revenue, marking the “Phoenix Core 1,” IP core the whole society of open source service launched. Zhang Weimin, Secretary-General of AVS Industry Alliance, says that the core of open source means phoenix in the industrialization of AVS standard road has taken an important step. The call of the open-source, AVS work
