Elimination of foreign standard AVS monopoly

According to the "First Financial Daily" report, on November 1, 2012, all terrestrial digital television receivers (including set-top boxes and all-in-ones) that are listed on the mainland of China must have built-in AVS decoding function. Otherwise, they will not meet the national standards and will not be able to sell. .

This is due to an industrialization move. On the 4th, the National Development and Reform Commission, the Ministry of Industry and other ministries jointly held a terrestrial digital television receiver and receiver standard press conference. This is after the release of the six national standards such as the general specifications of terrestrial digital television receivers and receivers (commonly referred to as set-top boxes) and receiver and receiver measurement methods.

The AVS national standard will be enforced for 10 years. Next year, China's digital audio and video coding and decoding national standard AVS has finally reached the moment of universal popularity.

Zhong Dengxiang, deputy general manager of Shanghai Guomao Digital Technology Co., Ltd., one of the leading research and development units of AVS National Standards, told the newspaper the day before yesterday: "On November 1 this year, these standards will be formally implemented."

Zhong Dengxiang said that in the first year of the implementation of the above standards, the terrestrial digital television terminals involved in the products such as the integrated machine and the set-top box will be free to choose the AVS national standard or H according to the specific circumstances. 264, MPEG-2 and other international standards.

However, one year after the introduction of the standard, that is, from November 1, 2012, AVS will have to be built-in as a standard. Zhong Dengxiang emphasized that this means that AVS national standards will be enforced by then.

Moreover, since all digital TVs must have terrestrial wireless TV reception capabilities, in the next year or so, all televisions sold in China and purchased by users will have built-in AVS function, and families that already own TVs will receive digital terrestrial TVs. The set-top box that the signal bought must also be available.

This also means that after one year, more than 400 million Chinese households will be able to play video in the same format. In the past years, due to the inconsistent standards for televisions and set-top boxes, not only has the terrestrial digital television industry chain been limited in its development, but it has also weakened the influence of the content industry.

Huang Tiejun, secretary general of the AVS Standards Working Group, said that the AVS standard is mainly used in digital television (terrestrial, cable, satellite, mobile phone), IPTV/triple play, high-density optical disc, network video, surveillance, content production/storage, etc. The most promising application in the future.

He believes that the unified terminal standard is expected to stimulate the growth of the entire industry, and the short-term effect is especially the development of the AVS chip and AVS terminal industry. He suggested that the state should deploy a new generation of audiovisual terminal standards as soon as possible on this basis.

Enforcement: Breaking the foreign standard monopoly Zhong Dengxiang said that behind every national standard, there is a history of bitterness in the industry, and so is the AVS national standard. Its birth was related to the development of the DVD industry that year. Ten years ago, a large number of Chinese companies entered the DVD market. However, in 2002, the International Standard Organization suddenly held high the patent stick. The patent licensing fee was as high as US$ 19.5, which accounted for 39% of the total production cost. Although it decreased afterwards, it still accounted for 32%. %.

This caused a large number of local companies to close down and hurt the entire industry. So the relevant departments are determined to develop their own standards. In 2002, the AVS Standard Working Group was established and the 2006 Standard was formally promulgated.

The advantages of AVS are mainly concentrated in the field of terrestrial digital television development. The advantages are high compression efficiency and saving channel resources. Zhong Dengxiang said that the compression ratio of AVS GB is MPEG

Double MPEG-2, H. The 264 compression ratio is comparable to AVS, but the implementation complexity is 30% to 70% higher.

But MPEG-2 and H. Prior to 264, it was in a monopoly position and the industrialization of AVS was initially very passive. For example, in the early days it had hoped for the IPTV market, but as of now it is far from universal. After more experience, the industry even thought it would "naturally die." At the end of 2007, the CMMB Shenzhen Summit of Radio and TV clearly stated that the CMMB specified codec standard was H. 264 and DRA. In the spring of 2008, it was once reported that the AVS or the mandatory national standard for terrestrial TV was dropped.

However, since 2009, related departments have begun to strengthen support for AVS. In June of that year, the Ministry of Industry and Information Technology approved the adoption of two national standards for receivers and set-top boxes. After a year of implementation, the Ministry of Industry and Information Technology (MIIT) forced internal AVS.

Series opportunities continue to emerge. In October last year, the State Administration of Radio, Film and Television (ARF)'s "Digital Radio Broadcasting Project" AVS transcoder was formally tendered. Afterwards, 5 cities such as Taiyuan opened AVS digital terrestrial television applications. In February of this year, Hunan opened a large-scale application of AVS provincial level. As of now, the AVS standard has started emergency testing in second and third-tier cities.

Zhong Dengxiang said that China has set 2015 as the last year for the overall realization of the “modulus revolution”, and AVS is expected to usher in the golden development period.

"The AVS is also a popular tool, which is the price." Zhong Dengxiang said, H. The fees for foreign standard patents such as 264 are above RMB 20 and there are hidden mines in the patent pool. The AVS charge is low, only 1 yuan is charged for each terminal.

Gao Wen, head of the AVS Working Group and director of the National Engineering Laboratory of digital video coding and decoding technology, told the newspaper that MPEG-2 receives about 10 billion yuan from China each year, and H264 charges 50 billion yuan more.
