Digital TV standard leveraging trillion market fusion with options

National Standards Committee recently released news, has "digital television terrestrial transmission system frame structure, channel encoding and modulation" as the national standard, so far, the terrestrial digital television broadcasting standard time and again after 12 years after the last introduced, will also start a comprehensive digital power in China trillion scale market.

Fusion criteria with selection

The national standard does not publish standard rules, according to SARFT had disclosed the news, the ground of the Tsinghua University DMB T standard fusion standard, Shanghai Jiaotong University ADTB T standard and TiMi standard of Academy of broadcasting science.

SARFT deputy chief engineer Du Baichuan has made it clear that the ground standard is the integration of standards, which does not exist to win the standard. Earlier, in the ground standard program competition, Shanghai Jiaotong University, the standard program and the standard program of Tsinghua University is the most important opponent, was also rumored to eventually win the competition in Tsinghua University standards.

Because there is no national standard published standard rules, outsiders can not know the standard setters is how to combine the three different frequency standards together. Insiders said that the Tsinghua University standard is a multi carrier, Shanghai Jiaotong University is the standard single carrier, belong to two completely different technology system, it is not possible to fuse together, the so-called integration is to load the receiver and modulator two standard on a chip, and then by the operators and users to choose which standard system.

Tsinghua University professor of Tsinghua University, said the standard participants Wang Xingjun interview, the ground standard is based on the Tsinghua standards as the main error correction technology combines the single carrier, Jiaotong University wide EPRI, standard fusion technical parameter of frame and frequency were unified regulations. However, modulation can be used for single carrier and multi carrier selection.

Wang Xingjun explained that in the European DVB T standards also exist several different modulation methods, the user can choose different modulation modes according to different content, our country standard in this aspect and its somewhat similar.

This explanation has not much difference with the previous rumors of market choice, ground standards allow the local radio and television operators to choose a single carrier or multi carrier rights.

Ground standards will be free to use

Concerned about the technical standards itself is a very boring thing, Guotai Junan Securities analyst Tan Xiaoyu media believes that the standard is to know who will be the biggest beneficiaries of the standard?

Shenzhen leaguer digital TV cable company general manager Ma Feihong believes that since the integration standard is based on the standards of Tsinghua University Tsinghua system as the main body, nature is the biggest beneficiaries, "Tsinghua standard system it is easy to test is now being upgraded to the national standard system."

Shenzhen force digital is the Tsinghua University digital TV standard of the industrial operation platform, has been carried out in more than and 20 cities in the country to carry mobile digital terrestrial television broadcasting test. When the standard is not determined, the local ground mobile TV operators worried that if the national standard is not the standard of Tsinghua, will face the risk of early investment vanish like soap bubbles.

Because SARFT has repeatedly revealed that the ground standards will be mandatory standards, not the national standard test system to be converted into a national standard system, the conversion time for 1 years after the promulgation of the standard.

Shanghai HD president assistant Wang Yao told reporters, Shanghai HD has from the chip to the system in Chengdu has made ready industrialization, Shanghai HD has technical advantages sufficiently occupied the future fixed reception of digital terrestrial television market.

Wang Xingjun believes that it is impossible to judge who will be the biggest beneficiaries of the standard, the final result needs to be tested by the market, who can win the market who is the biggest beneficiary.

It is worth mentioning that, who is the dominant position in the integration of standards and will not bring substantial benefits, such as patent fees. According to insiders, the relevant departments have been on the ground level of technical patent fees formed a provision, that is the standard for domestic companies to implement free. Digital TV market size

Digital TV terrestrial standard has been an important symbol of the process of digital television, in recent years, the domestic public opinion has been slow to start the digital TV market due to the delay in the introduction of standards.

According to the data, from the beginning of 1994, the National Standardization Committee will determine the development of HDTV standards strategy, and to develop a plan. Over the past 12 years, ground standards have experienced twists and turns. Analysts believe that with the digital terrestrial television standards, satellite digital TV, digital cable TV in China have been identified in the digital television transmission standard, is expected to have market trillion scale will be started. According to the relevant planning, China will be in 2008, Beijing, Shanghai and other large and medium-sized cities to launch digital television, by 2015, China's digital TV conversion is fully completed, and turn off analog TV programs.

From the beginning of 2004, SARFT began a large-scale and comprehensive promotion of the city's digital cable conversion, and the implementation of the city's overall conversion model in Qingdao, 33 provinces and cities nationwide promotion. At present, Qingdao, Shenzhen, Hangzhou and other cities have completed analog TV to digital TV conversion, is expected by the end of this year, China's digital TV users will reach about 10 million. Compared with the conversion of digital cable TV, terrestrial digital TV subject to the standard has not been released. Digital cable TV, satellite digital TV soon decided to adopt the European digital TV standard DVB-C and DVB
