Research On Mobile TV Terminal Based On TD-SCDMA

With the continuous development of mobile multimedia services, mobile TV business has been extensive attention. After analyzed TD-SCDMA which is the standard of 3G mobile communications, and CMMB which is the mobile multimedia broadcasting standard, I propose a point that mobile TV service based on TD-SCDMA terminal, the same mean that TD-SCDMA and CMMB are combined. What's more, the mobile TV is implemented on Android platform.CMMB includes primarily that OFDM technology, LDPC coding technology, interweaving technology and single frequency network. TD-CMMB system's hardware architecture includes communication module, application module, CMMB modules and multimedia modules. Introducing the RF circuit and CMMB circuit of the terminal system, and analyzing their work principle and technology standard. In terminal system, the RF circuit is the important part of the communication module, and the CMMB circuit is the important part of the CMMB module.Android mobile smart system, which is issued by Google, is standing out around lots of mobile system. and is popular by many mobile manufacturers. In the paper, I introduce the software architecture, application program, building environment, and the Human-Computer Interaction, which is the primary operation of the mobile TV on Android platform.
