China's hand machine television standards draw AVS over to one's side
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.
