#t-mmb

According to the news of Technology Office of General Bureau of Radio, Film and Television, the video national standard of the mobile phone will be confirmed finally at the end of 2007. The insider thinks, is controlling mobile phone video operation license plate and broadcasting and TV of the frequency band to be impossible and returning the contention of the selling machine TV national standard.

Sector standard CMMB which national Chinese General Bureau of Radio, Film and TV puts out, Beijing is new for shoreline T-MMB, Tsing-Hua University it last DMB-TH, China of news for CMB and communication broadcast committees standardized last " the TD-SCDMA + DAB + AVS " Association scheme,it is at China hand machine last " seven country make eight times " television standard At the time of the tangled warfare, the Chinese news, video compression standard AVS that were issued last year have already become and grabed a canonial new weight of TV of hand machine of China. Communication the intersection of broadcast and standardized floor, director of committee, bank up Germany with earth, show to " the first finance and economics daily report " a few days ago, China will encounter the trap of patent if China develops TV adopting or compatible South Korean T-DMB standard the mobile phone. And totally adopt the mobile phone TV technical standard independent of DAB/ DMB, its course of industrialization may be very long. He thinks, there is " DAB + AVS " Association scheme last a large number of patent fee and industry the contradiction problems of maturing status. CMB mobile phone television standard which Information Industry Department submits to national standard committee that DMB-TH, China of the news are that new shoreline T-MMB of Beijing, Tsing-Hua University insult. Beijing new the intersection of bank and collinear the intersection of technology and vice the intersection of director and Bin Wang show compatible South Korea T-DMB standard really the patent problem stores in, adopting AVS can really avoid the question of the patent fee. Chinese General Bureau of Radio, Film and TV broadcasts an anonymous technologist's then title of research institute, the standard discussed as to the mobile phone TV is nonsensical. Draw AVS over to one's side It is reported, T-DMB canonial patent fee is mainly divided into three parts, first, MPEG tissue collects H.264 (encoding video standard) to the operator according to broadcast time Patent fee; Second, MPEG organization collects H.264 patent fee to each receiver; Third, Samsung, LG charge T-DMB patent fee to the terminal producer of mobile phone TV, second and sum of item 3 among them are probably 7 dollars for each one. "If 500 million terminal stations with DMB cell-phone TV function of China's production and sales from the following 5 years to 10, need to pay patent fee of 3,500 million dollars, exclude the patent expenses that the TV operator of the mobile phone needs paying. " The floor is banked up Germany with earth and said. The online chief engineer's my darling in Guangzhou needs under command to show loyally, in case of equal code stream in the wide company of Guangdong, the results of AVS and H.264 are similar, it is 2/ 3 of H.264 that it decodes difficulty, and AVS collects the patent fee of 1 yuan only to the terminal manufacturer. Wang Bin represents, T-MMB can be with compatible T-DMB, but if China decides T-MMB is a national standard, do not use the compatible South Korean standard naturally. And T-MMB can adopt AVS, the so-called patent problem does not exist. AVS standard iron army Huang, general secretary of work group, reveal AVS accede to CMMB system as the information source standard formally already too, got involved in TD-SCDMA third generation mobile systems movable termination television standard work group at the same time, in order to obtain in future sound, video form to other sound, canonial advantage of the video. China's video compression standard AVS becomes the fragrant bun, grabs a canonial new weight of TV of hand machine of China as every large mobile phone TV scheme at one time. The operator puts into DMB However, it is process and maturing status question of different standard scheme industrialization to already pilot Beijing, Shanghai and what the operator of Guangzhou cared about of South Korean T-DMB at present. An anonymous operator's high level reveals, China's hand machine television standard is still in a scene of tangled warfare now, but each scheme has a progress problem of industrialization. Among them has basically totally given up mature DAB signal channel technology in CMMB standard, DMB-TH standard, still choose new signal channel technology, could succeed in in a short time, the problem exists greatly. This high level thinks, it is unable to issue finally that the tangled warfare may cause the mobile phone television standard of China, because China promises to world and realizes the TV application of the mobile phone on Beijing 2008 Olympic Games, so will let T-DMB pass finally probably. "In this way our input would not vanish. " This high level reveals, Beijing, Shanghai and operator of Guangzhou begin to popularize the application of mobile television by DMB terminal machine directly, claim this is a mobile television based on digital multimedia technology of DAB. Save China DAB "China should think how to recapture the initiatives of TV standard formulation of the mobile phone and industrialization from South Korea. " The floor banks up Germany with earth to represent, if China supports " DAB + AVS " Mobile phone television standard scheme, not merely can protect in fact DAB industry of billions of yuan of value of China, and can also create a unprecedented one, involve the market chance of the scale of ten billion yuan for AVS, and can realize within short-term that involve the industrialized process of TV of hand machine of China of the scale of hundred billion yuan. In fact, except " DAB + AVS " Association scheme support outside DAB,Beijing shoreline is to based on DAB too in T-MMB. Wang Bin shows, the advantage of DAB lies in being very ripe. The experiences of DAB products and operation of about ten years that T-MMB system can be integrated, and rely on DAB technical maturity products craft and industry chain, so this is a practical scheme. The floor banks up Germany with earth to point out, only adopts the technology of the mature DAB wireless transmission channel, could guarantee to move high-quality mobile phone broadcasting television signal receive under the state at a high speed.

It is reported WorldDMB the intersection of industry and the intersection of alliance and organization propose national power push away T-MMB become the major standard global cooperate, already, in addition many telecommunications of countries such as Sweden, Finland, Argentina,etc. run the company and already reach cooperating intention with the new shoreline Company of Beijing.

Beijing 2008 Olympic Games is closing on day by day, expects the mobile phone TV technology of having independent property right in China becomes glaring Hi-tech Olympics star.

Spread T-MMB evaluate the intersection of national standard and expert group select for the intersection of mobile phone and TV / move behind the the intersection of multimedia and national standard a few days ago, television standard CDMB camp main representative, federation of China Mobile carry out general secretary's building and bank up the Germany Professor with earth and issue the view and is thought all alone machine another, evaluate the group has passed, only means experts have reported to the leadship after accomplish it; He shows, CDMB important lying in fighting for the national standard, will survive to have little trouble in the future at the same time. Two principles The mobile phone TV mainly has three standards: TMMB, the scheme which Ministry of Information Industry recommends; CMMB, the sector standard which the broadcasting and TV department releases; CDMB, China Association for Standardization (abbreviate as and win a bid of the association) Standard released. Before this, T-MMB is evaluated the group selects for the mobile phone TV / moves the national standard of multimedia by the national standard expert, each side begins to show one's own attitude. On April 5, national Chinese General Bureau of Radio, Film and TV Technology Office chief Wang XiaoJie shows clearly, the national standard selects the course mismatch and standardizes the procedure, Chinese General Bureau of Radio, Film and TV will not use TMMB standard. Will it be night April 6, CMMB the intersection of camp and representative, the intersection of China Mobile and federation carry out the intersection of general secretary and floor, bank up Germany with earth with " give much trouble tripartite fight, the television standard commercialization of the mobile phone is delayed for three years " To carry on the generality summary. Say he, " it evaluate by expert on group at present though through,last the scheme to last opinions every committees national standard, from issue, have the intersection of segment and distance for national standard finally, evaluate group pass, only mean experts have reported to the leadship after accomplish it " . He claims in an article that gives Sina science and technology to specially send, the development of the mobile phone TV industry, the national related departments had once had important instructions. One is that mobile phone TV of China must adopt the mobile phone television standard with independent intellectual property right, this is a basic principle; The second is TV business of the mobile phone or the media, it is not the value-added telecom services, so State Broadcasting Film & TV Head Bureau (abbreviate in the department as the broadcasting and TV) The development of the TV business of the mobile phone has great leading roles. The floor banks up Germany with earth to think, these two principles are to make canonial important guidelines of TV of the hand machine of China. Independent intellectual property right purpose is to protect consumer's interests and the interests of the State, pay little patent fee to foreign countries as much as possible, know the initiative of industry's development. Operate the analysis of difficulty As to various technology, the floor banks up Germany with earth to report, CDMB cell-phone television standard to go on, integrate in the innovate based on Chinese General Bureau of Radio, Film and TV DAB sector standard and compiled code national standard AVS of Chinese audio frequency and video National champion machine television standard. CDMB standard channel and technical requirement of the information source are all the only one, namely DAB and AVS. Among them for realizing the most influential movable termination component of the competitiveness of industrialization and market, can realize and produce in 2008 in enormous quantities, the international technical indicator that totally reaches the mobile phone TV products will be required. The floor banks up Germany with earth to think in the article, DAPSK signal channel technology is that TMMB canonial shining point, independent intellectual property right are contributed and just lain in this at the same time, this technical indicator is said from raising the channel efficiency, capacity only, there is its rationality, however, in China, the broadcasting and TV have already confirmed STIMI and DAB signal channel technology as two major standards of the broadcasting and TV trade, on this basis, if TMMB adopts DAPSK signal channel technology, means needing the broadcasting and TV to release the sector standard of the third broadcasting and TV again, " the broadcasting and TV have already had two signal channels, get the third again, it is almost impossible " . Meanwhile, he thinks, the world of the wide department's institute integrated CMMB standard has the modulation schemes of three kinds of autonomous innovation, in order to adapt to the digital television signal receive under different wireless environments, the information source part can be that H.264 or AVS.CMMB has already set up the experimental transmitting station in even more cities of six major cities of China, will plan to cover the whole of China in the future. Until CMMB commercial to yet need time in system especially terminal industrialization at present, so, CMMB will adopt mature AVS directly maximal in order to reduce the possibility of the terminal cost in the future. CDMB does not focus on fighting for the national standard " CDMB important lying in fighting for the national standard, will survive to have little trouble in the future " ,The floor banks up Germany with earth to say like this. He analyzes at the same time, " the scheme of CDMB was agreed with by broadcasting and TV, CDMB is that inherited DAB canonially, and DAB is one of the wide electric sector standards " . He shows, in fact, the broadcasting and TV do not oppose and support to adopt CDMB (DAB +AVS) at the same time Innovative scheme of this kind of association. Because DAB is not merely become and mainly transmits the digital audio sector standard by the regulation in the department of broadcasting and TV, and DAB stipulates in order to launch the data traffic of the multimedia and account for the digital television business of 30% of the frequency resources, DAB is sanctioned being regarded as the transmissive legal channel technology of television signal of the mobile phone in China on behalf of the country by the broadcasting and TV trade department.
