Global mobile phone TV technology and business analysis

With the promotion day by day of the global 3G commercial process, the TV business of the mobile phone has received the extensive concern of the industry. In recent years, some movement operators in the world have introduced the TV business of the mobile phone in succession, what they mostly adopted is the technology of flow media based on cellular network. January of 2005, South Korean SKT satellite Digital Multimedia Broadcasting (S-DMB) After the business is put out, the TV business of mobile phone based on digital broadcasting television network begins the fast development. Technology way on the basis of the cellular network Technology of flow media The mobile phone TV business offered through the mobile network at present mostly adopt the technological way of the flow media. It adopts and moves technology of flow media, regards mobile phone TV content as a kind of data traffic and pushes away to users. The way to realize on different technological rule cellular networks is about the same too, in the cell phone termina (generally top-grade products such as a PDA cell-phone,etc.) equipped with operating system Have and install the corresponding playout software. The corresponding telecast is moved the operator or controlled and broadcast through corresponding SP too. From 2004, the movement operators from all parts of the world introduced the TV business of mobile phone based on cellular network one after another, they utilize GPRS or cdma2000lx network to offer the mobile phone TV business in a way of the flow media. By the look of business content, the video business of mobile phone based on 1xEV-DO network of SKT Company can relay the telecast directly, but other operators mainly offer non- real time video business such as the mobile phone short film, MTV. All in all, because of the restriction in factors such as the bandwidth of the mobile network,etc., the TV business of mobile phone based on flow media develops expectancy less than people. The cellular network broadcasts technology Because tradition move flow media realize way store a great deal of restriction in, begin, study how about realize broadcast of multimedia on mobile network in the world. 3GPP and 3GPP2 have proposed the multimedia radio multicasting service (MBMS) based on 3G network respectively And broadcast the multicasting service (BCMCS) Solution. These two kinds of schemes are improved on the basis of existing mobile communication network, provide the broadcast channel of descenting for user, the frequency used remains the frequency band of the mobile communiation system, in order to realize mobile phone TV provision terms through moving the data network. MBMS technology MBMS technology is based on the Off-The-Shelf WCDMA network, is totally move broadcast / multicasting transmission channel that the operator runs and controls by WCDMA after offering one set. MBMS can make use of existing both-way channel of cellular network to realize mutually. Besides the broadcastting service, MBMS can also offer more abundant multicasting business; Repair the mechanism through being point-to-point, realize the high download business of reliability. Can also realize flexible charging through the IC at the same time. MBMS not only can bear the weight of the TV business of the mobile phone, can also offer many kinds of PUSH business to user, for example move the advertisement, announcement information,etc.. The standard formulation of 3GPP relevant MBMS has already been basically finished, has begun to have MBMS apparatus and terminal products tested on the market at present. But because some major manufacturers such as Nokia, Motorola have been chosen the DVB-H cell-phone TV technical standard, having reduced to MBMS canonial input, the introduction time of MBMS commercial apparatus will be delayed, estimate that can not really put out until after 2007. BCMCS technology BCMCS technology is the technology based on that cdma2000 network offers the broadcastting service of the audio frequency and video. This technology can offer multicasting (one provide the identical content for more than) according to users' demand And unicast (one provides the individualized content for one) Mixed service. The development of BCMCS is to go from unicast to the multicasting of gold (GoldMuhicast) first ,Then go from multicasting gradual progress of gold to the multicasting of platinum (PlatinumMulticast) Course. In 3GPP2 at present, the gold multicasting standard based on EV-DORelease0 has already been made, in the course of making on the basis of the empty vocal imitation skill norm of platinum multicasting of EV-DOReleaseA. Technology way on the basis of the ground broadcasting television network The mobile phone TV on the basis of the broadcasting television network is technical and essential, but pass and make use of digital broadcast network of ground to realize the mobile phone TV business in the digital broadcasting way, and users, through integrating the module receiving the digital broadcast signal of ground on the cell phone termina directly, can realize it is received that the multimedia is machine format through clicking to the multi-point broadcast network. This kind of technology has not merely provided the rating of radio quality for user to experience, and there are advantages on construction cost of network and operation cost, so has caused telecommunication operator and the radio owner's extensive concern. The mobile phone TV technology based on digital broadcast & televisison web of ground produced from the digital broadcasting television technology of traditional ground, the frequency used is generally a frequency band of broadcasting television. The correlation technique company is on the technological foundation of the digital broadcasting television of original ground, research and develop the hand machine television broadcasting to the mobile phone characteristic, master technology includes DVB-H, T-DMB, ISDB-T of Japan and FLO of U.S.A. of South Korea of Europe,etc. at present. DVB-H technology DVB-H full name is DigitalVideoBroadcastingHandheld ld, it is a Digital Television Standard organization (DVB) of Europe For digital broadcast network through ground to portable /hand-held terminal offer multimedia transmission standard that the businesses make. This standard is a Digital Television Standard (DVB-T) of Europe Expansion application. DVB-H system can rely on DVB-T transfer system at present, through increase certain additional function and improve technology, make mobile phone portable equipment can receive the intersection of radio and television signal steadily. Because such characteristics as its technical standard is opened of DVB-H technology, have received the most extensive welcome in the world. Carrying on relevant research and experiment work actively in the operation commercial cities of a lot of countries and regions. ISDB-T technology ISDB-T is a industrial and commercial association (ARIB) of Japanese radio Digital television technique developed at the end of 1990s. In 1997, the industrial and commercial association of Japanese radio specially established the expert group of digital broadcasting (DiBEG) ,Responsible for advancing research and canonicalization of ISDB-T to work. In December of 2003, Japan broadcast way " ISDB-T " in its microwave digital television Under being standard,it make by " broadcast " The norm, specially offer the business to the cellphone subscriber. The downstream bandwidth to the mobile phone video ISDB-T of the needle is 630kbit/s at present. April 1, 2006, two of Japan has moved the operator NTTDoCoMo and KDDI Companies and has been both introduced and called the single-range ISDB-T commercial mobile phone TV business of OneSEG big, have established new cooperation mode with the broadcasting television operator, content provider. T-DMB technology T-DMB technology of South Korea is the digital broadcasting television technology of developing on the basis of DAB technology of Europe, can offer broadcasting television service to the mobile phone, special purpose terminal, vehicle carried terminal station. T-DMB of South Korea had already offered the commercial service at Seoul and circumference in July of 2005, the China service was put out at the end of 2006 after adjusting local frequency resources. The intersection of T-DMB and business of South Korea select 6 the intersection of broadcast and operator offer at present ' See the list) . There are a video, 3 pieces of audio frequency, a data channel in each operator; The first three families with network broadcast the operator to take original programs such as TV play, news,etc. as the core; The last three do not have operator of the broadcast network to hunt for a job individualized programs such as the information, news,etc., as the main fact. The broadcasting the way of the program delivers signal transmission that comes over to the broadcasting center the terminal station through the launching tower of radio, the shade area with bad signal passes on through GapFiller. Broadcasting the launching tower is have separately by KBC, MBC, SBS three companies, the transmitted signal that the operator without radio network facility rents the launching tower. Though South Korea has been making great efforts to popularize T-DMB technology abroad, the staple market of T-DMB is still in South Korea at present. FLO technology FLO technology is a new kind of multicast technology that American Qualcomm specially researches and develops in order to offer the TV business of the mobile phone. Principle, T-DMB and DVB-H,etc. that it realize broadcast technology similar, direct cell phone termina against specially because of it but design, and needn't consider and the original digital television network facility is compatible like technology such as DVB-H, so seem more rational technically. Though it put forward as how long,there are relevant for research and development progress, very fast of apparatus on FLO system. The high pass has already signed the cooperative agreement with U.S.A. Verizon Company, has offered the TV business of the mobile phone with the brand of Verizon. The spreading scheme in U.S.A. of high pass is to build a China network, then rent use to the operator and offer corresponding support by Qualcomm. The characteristic of FLO systematic maximum of Qualcomm is that design system utilizes the thinking of the television system of radio to come again, does not have because of technology of any Off-The-Shelf broadcasting television, so the input cost of initial stage is very high in a moment to other DVB-H. Make use of technology of the satellite network to realize the way Utilizing the satellite system to offer the technology of the business of a TV of the mobile phone is mainly the satellite Digital Multimedia Broadcasting (S-DMB)s of Japan and Korea S. Technology. This technical guidelines are to combine satellite TVs with mobile communication network, through loading the satellite television reception module on the cell phone termina, thus make users receive the video signal of satellites directly. Because the range that the satellite covers is greater, and the support to mobility is better, so generally think S-DMB will be a kind of more promising business. The above ground most places can receive the satellite signal directly, receive the shielded area in some signals, for instance subway and tunnel, in,etc. the BLDG, direct received signal have any problem, need to use GapFiller transponder, expand its coverage. In January of 2005, South Korean S-DMB network began to try commercially, offered the commercial business formally after trying for commercial 6 months. TUMedia Company is responsible for concrete operation, introduces 11 videos and channel of 25 pieces of audio frequency within the range of China at first under SKT. To user, if watching DMB, must buy the new mobile phone that can receive the satellite signal while moving the broadcast program. By March of 2006, S-DMB number of users already been close to 500,000. Author: Yu ZhiCheng Source: Post and telecommunications newspapers of people http://market..net/179/a185172.html
