National standards for terrestrial digital TV terminal implemented on November 1

Standardization Administration of the official release on the website of the "terrestrial digital TV receiver terminal (device) General Standards" (hereinafter referred to as "national standards"). "National standard" from November 1, 2011 into effect, requiring all of our production and sales of digital televisions must have digital terrestrial TV reception. Among them, China has independently developed video coding standard AVS and audio coding standard DRA November 1, 2012, after mandatory configuration, the current international OP296GS video coding standard MPEG-2 audio codec and Dolby Digital Plus as a standard option. China Electronics Standardization Institute senior engineer Zhang Subing told the "China MAX7219CWG+T Electronics News" reporter, "national standard" requirements, from November 1, 2011 onwards, the manufacturer can choose the specific circumstances of AVS or MPEG-2, DRA, or DU than the number of +, but after one year implementation of national standards, the end product must support AVS and DRA standards. As all must have digital TV terrestrial wireless TV reception capabilities, which means that within a year of China's market to buy all the TV and the user will have the decoding of AVS and DRA, the family has the TV to receive digital terrestrial to purchase television receiver (commonly known as set-top box) will also have the AVS and DRA codecs. It is understood that the national standard by the Ministry of Industry and Information Technology led the development, to guide our televisions, set-top box manufacturing and related industries, development of basic standards. Secretary-General Huang Tiejun AVS standard working group, said terminal through a unified industry standard can stimulate the development of standards AD623ARZ promulgated by the recent effects of the AVS chips and related industries will be explosive growth. Currently, a total of 17 chip companies at home and abroad support AVS decoding chip market: including domestic exhibition Motion Telecom (Beijing) Co., Ltd., Shanghai Longjing Microelectronics, Guoxin, Beijing Celestial, Haier integration, Taiwan mStar and ALi, etc., foreign companies including the U.S. Broadcom (Broadcom) and SigmaDesign, Europe, NXP (NXP) and STMicroelectronics (ST), South AD820ARZ Korea's Chips & Media, Japan's Fujitsu, chip covering HD, SD, phone, etc. a variety of terminals. Front-end products in the AVS, joint source (Beijing) Company, Shanghai Mao's China, the United States Envivo company, Telarity, Germany's EDbox companies developed a series of AVS encoder, which standard-definition and mobile video encoder has supported more than two sets of television programs broadcast in HD encoders already Peking University, Guangzhou, cable television and cable network test broadcast.
