CMMB will consider CDMB future integration or use of AVS standard-CDMB, mobile TV, AVS-communications industry
May in Tianjin Binhai International Convention and Exhibition Centre successfully held the annual session of industry events again this year not only to achieve a breakthrough in size, but also continued to attract foreign Mobile Communicate Industrial chain leader in all aspects of the broad participation. As one of the hotspots in this exhibition, China Association for Standardization Multimedia Communicate Broadcasting Standardization Technical Committee formally released CD MB Mobile TV Technical standards, which also declared a competition for national mobile TV standard camp added a heavyweight members.
CDMB standard is "TD-S CDMA + DAB + AVS "Digital Multimedia Broadcasting (TV) mobile phone system standard combination of programs for short. CDMB core technology based on DAB channel transmission technology and based on AVS source coding techniques, including DAB technology is the Radio and Television Department formally issued by the terrestrial digital audio broadcasting system technical specifications recommended industry standards, AVS, compared with the national standardization Management Council's national standards. It is reported that, CDMB standard is a fully independent country Intellectual property rights Mobile TV system solutions, and CDMB standard mobile TV industry chain includes all aspects involved in each year, as little more than 20 billion dollars to pay foreign patent fee, which for a long time subject to foreign royalties industry chain link enterprise is undoubtedly a good news.
However, we should see mobile TV as the important business of the 3G era, is faced with the 2008 Beijing Olympics Will be the golden opportunity to dispute the standard already shows "dogfight" situation. United States Qualcomm Research and development of MediaFLO, Nokia And so, backed by DVB-H And is quite popular in South Korea T-DMB, is an international three major mobile TV standards, but also the domestic industry standards promulgated by SARFT CMMB, Legend Technology The DMB-TH, Beijing's new shoreline of T-MMB and Huawei The CMB standards. Currently, CDMB Ministry of Information Industry approved standard has been officially released by the Ministry after submission of the State Standardization Committee, participate in the national mobile TV standard program of collection, I believe this will enable mobile TV standard of the national standard of competition has grown more heated.
Data show that in 2010 China's mobile TV subscribers is expected to reach 97.5 million, the market size will increase to 2.4 billion more. As the domestic 3G era is approaching, yet to be developed mobile TV market has become the focus of many manufacturers competing, especially in broadcasting and telecommunications in the two camps are clearly unwilling to give up control in this field. In the interests of the driven and intense competition, the telecommunications system is considered the standard of competition GB CDMB whether they can get the unanimous support of handset manufacturers are still variable. Currently, Lenovo, ZTE, China Mobile Hong and other companies have started launching CMMB terminal prototype, CDMB camp has begun to emerge a harbinger of differentiation.
Industry experts believe that the State Administration of Radio pioneered the CMMB standard, does not mean broadcasting system completely on its own to promote the development of the mobile TV market, as both from a technical perspective or from a market perspective is from not open telecommunications systems support. The triple play has driven broadcasting and telecommunications Cooperation And integration as an inevitable choice. According to the report of Analysys International, has a band broadcasting, content and policy advantages, and telecommunications to finance and Network Advantage, whether CMMB or CDMB, future radio and television operators, telecom operators and terminal manufacturers the distribution of interests between the need for a high degree of regulation from policy to be coordinated to ensure that the mobile TV supply chain, rapid and sound development. According to reports, CDMB standards development will take full account of the second phase of CMMB's integration with the widely ASTRI, CMMB has also been considered as the next step the issue by AVS. Clearly, cooperation and win-win model is gradually being recognized trade.
