Terrestrial digital TV standard in August will be immortal will impose

Signs, terrestrial digital TV standard is expected to be introduced in August this year, and are less likely to continue to delay.

No timetable for the delay introduced terrestrial digital TV standard time never had a firm timetable in the SARFT official mouth is always one by the end of the year will be introduced. The objective of the June 30th and are also introduced, soundless and stirless in waiting. Subsequently, the State Administration of Radio Science and Technology Committee said a senior adviser to Zhang Zhijian before the terrestrial digital TV standard is expected to be at the end of August formally promulgated. While the standard project organization development and Reform Commission official said that the standard is expected to be issued at the end of July.

Two authoritative departments, who is closer to the facts of the argument. Learned from the deputy chief engineer of the State Administration of radio reporter Du Baichuan before the digital terrestrial television standards will be introduced in the near future, and that this standard will not delay too long. At the same time, he also denied that the end of July issued a statement, but more likely in August.

According to Zhang Zhijian revealed that the relevant technical equipment is currently being tested, and has completed a round of testing, is expected to conduct a round of testing. According to the SARFT radio and Television Institute of Standards Committee, said the process of testing this technology takes about 1 months.

According to the standard procedures, for a month of time is required before the standard formally promulgated the public oriented publicity, although the text "standard of digital television terrestrial digital television terrestrial transmission system frame structure, channel encoding and modulation technology requirements" have been from the beginning of April to seek the views of industry experts. If the above time to measure, that is, the test time plus publicity time, the ground standards promulgated in August will be more determined.

Test will not change the standard

Digital TV ground standard is a three party integration program, the upcoming DMB-T standard of Tsinghua University, Shanghai Jiaotong University, the ADTB-T standard and the Radio Science Research Institute TiMi three standards for the integration of the program.

This is also the main reason for the standard has not been promulgated. Single carrier and multi carrier standard of Shanghai Jiaotong University, Tsinghua standards have technical expertise, who can not get standard units using their own standards, game between the two main criteria of the standard that the delay is difficult to introduce. The ultimate solution is to make a single carrier system and a multi carrier system at the same time in a chip, and then through the software control by the user to choose which system to use.

Insiders said that since the "fusion" fight the enemy separately, which means do not appear five or six years of technical change, technical testing is to test the Shanghai Jiaotong University and Tsinghua University can make equipment according to the fusion scheme.

There will be no change in technical parameters, but will not change the standard, this test is only to allow enterprises to make qualified equipment based on the standard products." The person said.

It is reported that, according to the Tsinghua University, the integration of standard program manufacturing equipment has been tested before the end of June, which is the standard of the latest power source issued in late June 30th. Is now being tested in Shanghai Jiaotong University, according to the fusion program made equipment.

Ground standards will be enforced

Digital TV transmission standards include three standards: ground transmission standards, cable transmission standards and satellite transmission standards. Digital TV cable transmission standards and satellite transmission standards have been identified using the European standard DVB-C and DVB-S. Only the ground transmission standard is the use of domestic standards, in the context of advocating technological innovation, its significance is particularly important.

People involved in the ground standard said, Shanghai Jiaotong University and Tsinghua University is the standard of independent innovation based on the original standard in Europe and Japan and South Korea on the standard, the standard selection of fusion with independent intellectual property rights of three kinds of standard parts, therefore, has the independent intellectual property rights.

Selected with independent intellectual property rights of the national standard can not only avoid paying royalties to foreign enterprises, but also can promote the development of the domestic manufacturing industry, the cultivation of digital TV equipment providers have their own technology, establish and improve the digital TV industry chain.

At present, Tsinghua standards and standards have their own leading enterprises. Shenzhen leaguer digital television limited by Tsinghua University standard in the country about 20 city to carry out ground mobile TV project, Shanghai HD Digital Technology Industrial Co Ltd is the University standard, the promotion of digital television operation in Shanghai Chongming Island.

It is reported that the deputy director of the State Administration of radio, Zhang Haitao said in an internal meeting that digital terrestrial television standards will be a mandatory national standard, transmission, non national standard equipment will be removed from the acceptance of the market. At present, in Beijing, Shanghai, Hangzhou and other places on the ground mobile TV terrestrial transmission standards in europe. Analysts expect the State Administration of radio, film and television will set a timetable to change the situation in most major cities using European transmission standards.
