The National Standard For Digital Television Terrestrial Broadcasting Will Be Introduced In August Next Year.

Yesterday (August 30th), the National Standard Committee issued the "DTV terrestrial broadcasting transmission system frame structure, channel coding and modulation" standard on its official website. The National Standard Committee said that the standard supports high definition television, standard definition television and multimedia data broadcasting, and other services to meet the needs of large scale fixed coverage and mobile reception. This standard was officially approved in August 18, 2006 as a mandatory national standard and implemented in August 1, 2007. After the promulgation of this standard, China will face the transformation from analog signals to digital signals. Two years ago, the domestic color TV enterprises have already devoted themselves to the research and development of digital TV. SKYWORTH, Konka, Changhong and other enterprises have launched the digital integrated machine. Shen Jian, a spokesman for SKYWORTH group, told reporters yesterday that SKYWORTH's sales promotion in one machine in Nanchang is steadily advancing. Ye Tao, general manager of Konka multimedia marketing division, told reporters that at the beginning of this year, Konka's 30 thousand computers and cards separated digital TV one machine exported to the US market, becoming the first batch of similar products that landed in the United States in China. According to expert analysis, the domestic market sells 35 million sets of color TV sets annually. By developing a digital TV all-in-one, converting incremental users directly into digital TV users, it will take about 10 years to complete the transition from analog to digital. Mao Zhengrong, an analyst at Everbright Securities, believes that the standard will not only affect the industrial chain links such as equipment chip manufacturing and operation, but also will have a significant impact on the development track of terrestrial digital TV, mobile TV, building TV and even the mobile TV industry. In the industrial chain affected by the digital TV terrestrial transmission standard, many key enterprises, such as G Tongfang, A music and G Nanyang, have been soaring this week. (Wang Xuejin) background information: five years of game theory, the introduction of the digital TV terrestrial transmission standard started from the national digital television special working conference in 2001, aiming at the collection of the digital television terrestrial transmission scheme initiated by China. It has gone through 5 years of research, testing and discussion. If the National Science and Technology Commission started the HDTV project in 1994, it will take 12 years. Since 1999, the national development and Reform Commission has taken the lead with the Ministry of science and technology, the Ministry of information and production, the General Administration of radio, film and television, and the General Administration of quality supervision and quarantine. Five ministries and commissions have jointly established a digital television leading group. This leading group has identified two tasks, namely, the establishment of a national standard with independent intellectual property rights, and the localization of core technologies and components. With the introduction of the digital television terrestrial transmission standard and the production of independent intellectual property chips, the two tasks have been completed. However, because of the single carrier scheme ADTB-T led by Shanghai Jiaotong University and the multicarrier DMB-T led by Tsinghua University, there has been fierce competition in standards. Since 2003, the development and Reform Commission has led the establishment of a joint working group of the Academy of engineering. It has studied and tested this standard, and has been the leader of Wu Hequan, vice president of the Chinese Academy of engineering. Up to now, the two standards of "fusion plan" have been brewing. In this process, the radio and TV Standards Committee, which has been responsible for broadcasting standards, has organized many tests and discussions. Since 2006, the broadcasting and TV Standards Committee has conducted two publicity on the intranet, and has openly solicited opinions. From June to now, after many improvements and corresponding examination and approval procedures, the 5 year DTV Terrestrial Transmission Standard was finally promulgated. After the promulgation of the standard, the first task is to transform the existing terrestrial analog television broadcasting into digital television broadcasting. On the one hand, analog TV is broadcasting, on the other hand, digitalization is also being broadcast. Finally, the overall transformation from analog to digital broadcasting will be realized step by step. In addition, the mobile digital TV broadcasting service will be carried out in conditional urban areas. The standard of digital TV terrestrial transmission is only the channel transmission standard. At the same time, it will also speed up the formulation of other digital TV standards, such as source and interface, so as to facilitate the development of terrestrial wireless TV service. After the standard is released, the whole industry chain will start, and the whole scale will be trillion yuan in the next few years. At present, there are about 1 billion 400 million TV sets in the world, of which more than 400 million are in China. Apart from 112 million cable TV outdoors, all of them are potential users of digital TV terrestrial transmission standard, and the users of mobile TV and mobile phone are even larger. At present, many key enterprises in the industrial chain affected by digital TV terrestrial transmission standards, such as G shares in A shares (600100. SH), 600651.SH music, and G Nanyang (600661.SH) have been soaring this week.
