The broadcasting and TV CMMB scheme are squeezed Absent from the mobile phone TV national standard

Though General Bureau of Radio, Film and Television has announced the mobile phone television standard CMMB (hereafter referred to as unilaterally " The scheme of broadcasting and TV " )It is a recommendatory standard, but not given up fighting for national canonial efforts with Technology Office leading T-MMB of Ministry of Information Industry.

Recently, the reporter learns, in the mobile phone TV national standard scheme that the national standardized committee collects, three schemes such as CMB that T-MMB, DMB-TH and China of Tsing-Hua University that only receive Ministry of Information Industry are, and the broadcasting and TV CMMB scheme announced first were not submitted.

Meanwhile, on behalf of Information Industry Department T-MMB canonial new shoreline of Beijing, represent Ling Xun and China in Tsing-Hua University of Tsing-Hua University standard DMB-TH are, have already proposed " TD-SCDMA +DAB +AVS " to the standardized committee of the radio of communicating Association scheme. In this scheme, the broadcasting and TV have already been squeezed on one side.

It is reported, T-MMB of TD-SCDMA and Information Industry Department comes down in a continuous line. The new shoreline director of technology department Wang Bin of Beijing claims, 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, this is a practical scheme.

Communication the intersection of broadcast and standardized relevant person, director of committee, show to reporter, " DAB+AVS" Association scheme last a large number of patent fee and industry the contradiction problems of maturing status. Bin Wang represent too, T-MMB but Israel compatible South Korea T-DMB, but if China decides T-MMB does not use the compatible South Korean standard naturally for the national standard. T-MMB can adopt AVS too at the same time, the so-called patent problem does not exist.

The Huang 's of AVS standard general secretary of work group says, AVS joins CMMB system formally as the information source standard, having got involved in TD-SCDMA movable termination television standard work group at the same time, " we will play important bringing function together in the middle of this " .

If broadcasting and TV standard is exclude from mobile phone TV national standard, mean the intersection of failing and Olympic good opportunity. For this reason, AVS has proposed a half-way house - -Include CMMB technology in merging the scheme.

The professional personage thinks, this pair of CMMB can yet be regarded as a good scheme. Because DAB technology has the maturity operation experiences of over 10 years, the starting of broadcasting and TV CMMB has still just begun, produce from chip to terminal station and has not really started, the broadcasting and TV must merge T-MMB while wanting to develop the mobile phone TV.

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.

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.

China's hand machine TV technologies are expected to assault the international standard

Have " the fifth media " Mobile phone that claim TV global without being considered as for information industry new commanding point. Chinese Government promises to offer mobile phone TV service during Olympic Games in Beijing of 2008, thus make it become focus that pays close attention to China

A few days ago, China hand machine the intersection of TV and the intersection of technology research and development and the intersection of Beijing and new the intersection of shoreline and Company of principal organ one of disclose Mobile of T-MMB their to media for the first time, technological overall picture and industrialization process such as special purpose chip, transmitting set. It is introduced, collinear T-MMB technology can realize on the maglev train at 500 kilometres per hour that watches the telecast smoothly with the mobile phone on the new bank, many kinds of technical indicators have reached the international leading level, it is expected to become the international standard.

"Compare with international major mobile phone TV technology at present, T-MMB with China's independent intellectual property right has leading nature on key technical indicators such as excursive, anti-interference, power consumption, spectral utilization factor, covering the radius,etc., realize for the first time, transmit in the whole world and large standard signals of receiving end compatible, " The new shoreline technology vice director Li XuMing says.

It is in T-MMB from in move, UNICOM, defending being coherent, telecommunication academy and shoreline Companies new introduce from Chinese mobile phone television system which technician research and develop independently jointly. It is high in efficiency that this system transmits, can transmit there times more mobile phone telecasts than present world level under the equal bandwidth condition. T-MMB system can reduce cloth network cost and terminal cost greatly, thus is favorable to industrialization, and make the cellphone subscriber benefited. In addition, the international major mobile phone television standard that T-MMB systems can be a plurality of compatible, it is expected to explore world market, become the international standard. It is reported, the multidigit academician of the Chinese Academy of Sciences and Chinese Academy of Engineering has already recommended T-MMB to central strength.

At present, T-MMB industrialization makes good progress. As far back as August of 2006, T-MMB has already been tested through the high-power of external field that Technology Office of the broadcasting and TV organized. Through the cooperation of numerous famous enterprises outside and China, until the beginning of 2007, the technical indicators of all capital equipment such as the multiplexer of T-MMB, transmitting set, receiver, transponder have already all passed tight severe laboratory limit test, the capital equipment that T-MMB involves in the mobile phone TV industry chain all reach the industrialization level.

The reporter has seen in the new shoreline company he numbers for the TV special purpose chip of the NF9001 cell-phone. This chip has already finished the project sample wafer, batch productino commercial chip will have produced and have put out in November. This section being only the intersection of 5x5 and millimetre, stamp half even little chip, plant the starting with machine than nail, can realize that watch the function of the telecast through the mobile phone. It is reported, there is famous mobile phone manufacturer's seeking and new shoreline cooperation outside many Chinas at present.

Insider show, fewer than one year already from the intersection of Beijing and Olympic Games, China hand machine TV set industry will you please provide service and already become the problem that can't be avoided when the time comes. As far as reporter know, it is the most key turning off too that the video national standard selection of the mobile phone has already been entered finally at present: Survey. Including CMMB of the wide department's institute, DMB-TH of Tsing-Hua University, it is new bank it is collinear for T-MMB, China for CMB and the CDMBs of China Association for Standardization if you can't put forward to national standard committee, contend for already by the applications of national standard to an inner five.

"As to this time with compete on the same stage while being canonial while being other, new shoreline finish entire preparation already. And T-MMB outstanding technical feature makes it assault international canonial ability even more, " Li XuMing says. Have, it becomes global standard prospects to be whether one that national standard evaluated this mainly consult the factor too.

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.

The academician jointly recommends T-MMB to become the mobile phone TV national standard

Recently, the mobile phone television standard receives the media and high concern of industry, this not merely involves whether China could seize commanding points of the information technology frontier, and because the mobile phone TV is linked to Beijing 2008 Olympic Games. The reporter knows, many academicians of the Chinese Academy of Sciences and Chinese Academy of Engineering have already jointly written to the national related departments, strength recommends T-MMB with all independent intellectual property rights and becomes the mobile phone TV national standard, and hope to seize the opportunitying makes this standard become the global major standard. The reporter still knows, China Mobile, CHINAUNICOM, China have defended open, the telecommunication academy and new shoreline Company of Beijing already in the first ten days of January of 2007, jointly declare the mobile phone TV / move the national standard scheme of multimedia to the national standards committee, the body of this scheme is T-MMB cell-phone TV technology.

The competition in the field of information technology of television standard of the mobile phone is very fierce, the science and technology in this field of China has researched and developed and made multiple great breakthroughs. Have all independent the intersection of T-MMB and technology of intellectual property right until expert think and move broadcast technology of multimedia outside the a lot of China. T-MMB can overall compatible international the intersection of multimedia and the intersection of broadcast and standard DMB and a big mobile phone of the intersection of television standard and DAB-IP and the intersection of T-DMB and standards in the world not merely, and the characteristic is obviously superior to the above-mentioned two standards, for instance, T-MMB has adopted the utilization factor technology of high-frequency spectrum, the television channel that can broadcast under the same bandwidth condition is twice that of DAB-IP and T-DMB technical standard. Many foreign companies such as global DAB organization and Microsoft think, once T-MMB becomes the international standard, the mobile phone TV will become and realize the second largest roamed in the whole world following communication of mobile phone wirelessly to propagate the service item.

The academicians point out in jointly believing, T-MMB makes the technology from China have an opportunity to become the major standard in the world in the key industry for the first time. To the intellectual property right question of T-MMB, the file of State Intellectual Property Bureau that the new shoreline Company of Beijing provides shows, T-MMB has all independent intellectual property rights, do not need to pay expenses of any patent to foreign countries. This is that academicians try hard to recommend T-MMB as one of the national canonial important reasons of TV of the mobile phone too. In addition, adopt T-MMB technology, can fully utilize Off-The-Shelf frequency point resource and network facility, cost comparison is low, easy to realize industrialization rapidly. Already commercialization of key equipment such as T-MMB transmitting set, multiplexer, receiving the chip, and the high-power of external field already arranged through Technology Office of General Bureau of Radio, Film and Television in August of 2006 tests. According to new shoreline Company of Beijing, many mobile phones manufacturers have an optimistic view of this enormous market very much outside China, the mobile phone prototype machine adopting T-MMB technical chip and producing has already been finished near. Europe and the intersection of South America and many of the intersection of wireless communication and Company interested in T-MMB technology very much too, have already signed the memorandum of understanding with 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.

The floor banks up Germany with earth: The mobile phone television standard is that the routinization is only technology

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.
