AVS independent audio and video standards as national standards have been for many years, but Industry for various reasons has not been well developed. Strong support at the national terrestrial digital

TV

Against the backdrop, AVS seems to find its most suitable soil industrialization.

“The reason why we should develop our own AVS (Audio Video Coding Standard State) and to promote their industrialization, is to allow domestic companies from foreign standards

Monopoly

Of stress. “On the issue of industrialization of AVS, AVS, Team Leader Professor Gao Wen said that there is no independent standard, there is no independent industry, AVS technology industrialization in China

Electronic

The development of information industry has become increasingly important.

AVS as the national standard has been promulgated for three years now in large-scale industrialization of the start-up period. “Everything has a certain process of development.” Several people in the industry questioned the pace of industrialization of AVS is too slow to respond to Professor Gao Wen so. He believes that “the current pace of industrialization of AVS, although not fast, but overall it is still normal, the other’s technical standards, such as MPEG-2 (International Digital Audio Video Coding Standard), and its industrial development also gone through a process of slow to fast. ”

Key used in terrestrial digital TV

AVS standard is a basis for common standards, a wide range of applications, but applications in all areas not go hand in hand, and its commercial use began in the field of telecommunications. June 2007, China Netcom Corporation announced its new Internet TV IPTV (interactive Web TV), the use of domestic AVS audio and video decoders, thus beginning the big screen AVS commercial applications. Followed by China Unicom is the AVS-IPTV commercial operations to a climax, not only established the technical standards of AVS-IPTV system, and also its international telecommunications union (

IT

UT) recommended, making IPTV four international audio and video codec standard.

But the focus of AVS applications are focused on terrestrial digital television. August 2007, Hangzhou Radio and TV terrestrial digital television transmission in the start of national standards, the announced use of AVS as its codec standard. The terrestrial digital TV “double the national standard,” the official operating system to achieve the AVS standard in the field of the first commercial radio and television.

AVS since the development of digital terrestrial television landmark event also includes: in July 2008, the Shanghai Oriental Pearl TV Tower try to begin broadcasting digital television (SDTV) terrestrial broadcast standard using AVS. Subsequently, the Shanghai SVA Group, launched the “double the national standard,” the AVS terrestrial digital TV terminals one machine SVARM8000A, break the AVS standard in terrestrial digital TV in the terminal bottleneck. Shanghai has become an area of AVS in the development of digital terrestrial city, while in Guangzhou, Taiyuan and Qingdao, Shanxi, Hunan and other places, AVS has entered the stage of large-scale business.

AVS in the development of terrestrial digital TV main advantages is its high compression efficiency, compared to MPEG-2 standard can save channel resources more effectively. Professor Gao Wen advantages that this technology will continue to promote the development of AVS in the field, while the AVS Industry Alliance, said Zhang Weimin, the Secretary-General, with the standard of terrestrial digital TV terminals introduced, AVS standard in the field of development will have broader prospects .

Reporter learned that, as China’s digital TV terrestrial transmission standard drafting and one of the core R & D, Shanghai, is mainly responsible for high-definition high-definition digital TV ASIC development and

Sell

, The AVS national standards have been integrated chip mass production, sales of more than one million, accounting for half the market. In addition, including Spreadtrum, Long Jing, China Core, STMicroelectronics, including eight companies have entered the market AVS chips, Long grain self-developed AVS HD chip, and even low cost

DVD

HD disc playback.

Present, AVS main products include chip form, set-top boxes, machine, etc., Sichuan

Changhong

, Shanghai SVA,

Hisense

And other companies are active in dozens of set-top boxes and televisions AVS development, development of these enterprises AVS industrialization swept away obstacles to limit the terminal.
