Xiaojie: CMMB Development into the sprint period

Entering 2009, China Mobile Multimedia Broadcasting (CMMB) development has made a substantial breakthrough. By the end of March, there are 17 provincial branch offices to obtain the official operation of CMMB. CMMB Operating Company--China-Canton Satellite Mobile Broadcasting Co., Ltd. said that the company has already completed the construction of CMMB operation support System, is expected to complete the second quarter of this year CMMB billing system, settlement system and the existing network of CA encryption deployment related work.　　"July 1 will have a commercial trial operation of the basic conditions, the year will complete the establishment of all provincial branches, and achieve national commercial operations."　　Recently, this newspaper reporter on China Mobile Digital Multimedia Broadcasting (CMMB) the development of the current situation, the future planning interview the State administration of Science and technology director Xiaojie.　　cmmb--Radio and television supplement and extension Reporter: Director Wang, I am glad you accept this interview, please introduce the story of CMMB and the development of the background? Xiaojie: To sum up, the development of CMMB mainly through three stages: technology development and research stage, standard system establishment and equipment industrialization stage, scale technology test stage. 2002-2006 years is the first stage, SARFT Science and Technology department through the development of mobile Multimedia broadcasting technology System Research, Canton Institute and some scientific research units, some enterprises have been hard to tackle the key technology breakthrough. 2006-2008 years March is the second stage, through the mobilization of the enthusiasm of enterprises, not only accelerated the process of industrialization, technical standards system is gradually improved, October 2006 We promulgated the first industry standards, the current total promulgated 10 technical standards and 10 technical specifications, There are a lot of patents and technologies that companies contribute. Since March 2008 to the third stage, we have established a coverage network in 37 cities nationwide to achieve the goal of serving the Beijing Olympic Games. Through the practice of the Olympic Games, it is proved that CMMB is technologically advanced, the industrial chain is mature, and it is feasible. Since October 2008, we have been carrying out large-scale technical experiments in the national cities.　　At the same time, we are establishing operation support system, and set up operation main body, establish operation mechanism.　　Reporter: You to CMMB for the user base and the services provided by what the idea? Xiaojie: In the past we watch TV can only be fixed to receive, CMMB mainly to meet people anywhere mobile portable reception needs. CMMB service positioning and traditional radio and television services, it is positioned as a small receiving terminal 7 inches below, user-friendly mobile reception, is the existing radio and television services supplemented and extended to fill the service gap. Learn from foreign experience, we through the investigation and analysis of the clear CMMB business positioning: anytime, anywhere watching TV. Because it is to fill people's fragmented time, so the reception behavior is often not active demand, a destination to see a program, but randomly, passively to receive, will pay more attention to some fast programs and news. CMMB not only provides radio and television programs, but also provides comprehensive information services, including weatherInformation, traffic information, stock market, electronic newspaper magazine, push on demand and games.　　Business planning and positioning should be based on the technical rules of CMMB and people's reception behavior to carry out a comprehensive consideration. CMMB-2 will realize interactive function Reporter: CMMB cost how to build the network?　　is national promotion expensive? Xiaojie: CMMB use broadcast way to achieve coverage, a launch point can cover dozens of kilometers, the cost is low, and will not appear congestion. CMMB Network can use the existing radio and television transmitter and tower, increase the transmitter and antenna, low investment, and can be put into use immediately.　　This is a cellular network with wireless communications, a launch point can only cover one or two km different. Reporter: Current user's viewing habits, viewing mode is changing to the interactive on-demand, it should be said that can not interact is the lack of CMMB.　　What do you think of this problem, is there a plan to deal with it? Xiaojie: You speak very well. CMMB is now the first generation of products, since 2008 we began the second generation of product technology research and development, its biggest feature is to achieve interactive function, I believe it will soon be to the market.　　We tentatively call it CMMB-2.　　Reporter: Interactive network and a single broadcast-type network, CMMB-2 products will significantly increase the cost of the network and operating costs? Xiaojie: No. Interaction can be achieved simply by adding a device to the transmitter, and the cost of the device is low. With the rapid development of technology, new technologies and schemes are emerging, new technologies have greatly reduced the cost of network and operation.　　In particular, we have mobilized the enthusiasm of the enterprise participation, a lot of technology, patents are the successful development of enterprises.　　Reporter: You mentioned above 2008 years CMMB in 37 cities to establish the cost of covering the network is how much?　　Xiaojie: We are very careful, only 150 million yuan.　　Reporter: In cmmb realize Interactive, charging way on the diversification, this aspect have what plan? Xiaojie: CMMB payment system, can be paid through UnionPay, also can use electronic wallet way, buy recharge cards can also. In the technical framework, we provide a platform for various value-added services. A number of operational standards have been developed and are involved in various operations.　　Including the sports lottery services, online games, stocks, funds and other services are being approached. CMMB let national enterprises dug to the first bucket of gold Reporter: CMMB industry chain is what?　　What role do governments and businesses play in each of them? Xiaojie: CMMB development can not be separated from the Government and enterprise support.　　The government should understand the market to set up a reasonable plan, to set up an effective mechanism, but also to coordinate the pace of market development, the first enterprises to perceive the market, the best understanding of the market, but also the best understanding of what kind of product technology to adapt to the market. CMMB industry chain is divided into two: one is the technical equipment industry chain, one is the business industry chain. In accordance with the development of technology and equipment industry chain, from research and development to the introduction of standards, to equipment industrialization, and then to market applications, this process generally takes 10 years. CMMB Rapid development has two reasons: first, the opening, the mobilization of various links related enterprises together for industrial development, we have to save time in parallel. Radio and television is the application sector, not relying on patents and technology to profit, just for technical applications, as soon as possible to develop the industry. Second, the industry-led, industry-competent departments responsible for planning, coordination, to create an environment for industrial development. Technical innovation can not rely on executive orders, rely on enterprises, enterprise innovation ability to mobilize, than any one of the executive branch of the impetus is stronger. CMMB development broke in the past in the electronic manufacturing, foreign products first promotion, national industry after the game rules, let the national enterprises to dig the first bucket of CMMB gold.　　Because of the rapid formation of CMMB industry chain of scale, so that CMMB equipment products inexpensive, and ultimately to consumers benefit. The business industry chain is from the upstream content provider, program integrator as the originator, through the network operator transmission, coverage to downstream of receiving and service.　　According to different service positioning and business structure, to meet the needs of users, the chain of all sectors in accordance with contributions to gain.　　Reporter: Please introduce the three net fusion has any new progress. Xiaojie: According to the National development planning and Kwok [2008]1, the realization of the three-network integration should be based on the broadband Communication network, digital television network, the next generation of Internet. This is a required technical condition. However, China's current three nets do not have this condition, communication network is not a broadband communication network, television network is analog has not fully turned into digital, the internet has not gone to the next generation of the Internet, so the three-net integration is a gradual process, is a development direction, is not currently said fusion can be integrated immediately, Not the merging of people's imagination. But with the development of technology, especially the development of digitalization, it is possible to provide three kinds of services on one network.　　In fact, triple-net integration is only a description of three kinds of business in the future, not a system or a physical concept. Compared with the three nets, the broadband network has the widest bandwidth, the most advantageous transmission of radio and television programs, the digital voice service, Internet business is easy. But in turn, it is not easy to provide another two-net business on other networks, and more investment is needed. We should vigorously promote the digitization of radio and television, accelerate the construction of next Generation Radio Network (NGB), at a higher level, higher level to promote the integration of the three networks. The realization of triple-net fusion, each NET can provide full-featured business, more functions, lower prices, the national will benefit the most.　　Its core function is to realize fast data transmission.
