[industry Observers] China Mobile Tv Technology Development In China - Mobile Tv, Radio And

Today, as the world scientific and technological progress and rapid economic development

, digital, network, information broadcasting and television industry become an inevitable trend. Digital cable, digital terrestrial broadcasting, direct broadcast satellite television, Internet video / audio broadcasting, 3G (3rdGenertion), the rapid rise of digital multimedia broadcasting, radio and television system from analog to digital is a big change in technology. This change means more forms of technology changes, more importantly, it provides for the broadcast media, a wider space for development, indicates that public broadcasting is the party's positions, but also a new, promising important information industry. This will be combined with modern radio communication technology, mobile TV technology development in China try to do analytical thinking.

1, concepts and classification of mobile TV

Mobile TV refers to the use of telecommunications and broadcasting networks, mobile communication terminals for digital content broadcast (including audio, video and data content) of the new mobile multimedia services. Achieved by way of mobile TV services there are two main points: first mobile communications network streaming methods; second digital radio broadcasting and television networks broadcast.

1. Mobile network streaming methods Today, domestic and international mobile operators launching mobile TV business mainly depends on the mobile communication network. Now China Mobile's mobile TV service is based on GPRS (GeneralPacketRadioService) network, China Unicom is to rely on its CDMA1X (CodeDivisionMultipleAccess) network. This mobile TV service is the use of streaming media technology to mobile TV as an introduction to data services. Either GPRS or CDMA1X mobile phone with the operating system needs in the mobile terminal (typically high-end PDA mobile phone and other products) to install the appropriate player software, and the corresponding television program by the mobile communication company or by the corresponding SP ( service providers) to organize and deliver. Currently, better support for the 3G mobile TV service standards, the standard to support voice and packet switched data. Global mainstream 3G standards 3, the European WCDMA proposed Tianjin Radio and Television Film Group of the Yellow River (WidebandCDMA), the United States proposed CDMA2000 and China with independent intellectual property rights of third-generation mobile communication standard TD-SCDMA (TimeDivision-SynchronizationCodeDivisionMultipleAccess). TDSCDMA communication standard in the field of China's first major breakthrough, is the main communications manufacturers the major achievements of independent innovation, in May 2000 was accepted by ITU as 3G international standard. The three criteria are promulgated by China's Ministry of the latest mobile communications industry standards.

2. Way digital radio technology Adopted digital radio technology digital terrestrial broadcasting or digital broadcast satellite of ways. It does not link through the mobile communication network, simply install digital TV handset receiver module (decoder), direct access to digital television signals. At present, the broadcast mobile digital TV standards, there are three main international standards, the European-led DVB-H, South Korea led the T-DMB and Qualcomm's MediaFLO standard lead. SARFT in China with independent intellectual property rights set the industry standard CMMB has also been enacted.

Second, mobile TV standard profile 1. Mobile Streaming mobile TV standard

(1) CDMA2000

CDMA2000 is evolved from the CDMAOne third-generation mobile communications technology. In fact, CDMA2000 standard is an architecture, called CDMA2000family, it contains a series of sub-standard. CDMA2000 is the initiator of the United States and South Korea-based to IS-95CDMA standard manufacturers and operators, CDMA2000 inherited the narrowband CDMA IS-95 features of the system, network operators can be in the narrow-band CDMA network to replace or Some network equipment to increase the transition to 3G.
