| Abstract: | The method to realize CMMB function on the basis of MTK system is described. The structure of hardware module and the realization of software are elaborated. Taking the common platform MT6255 as a communication module to combine the multimedia chip TCC7690 with demodulator chip IF201, the audio signal is transmitted through an audio codec WM8371 to a speaker, and the bitmap data is sent to a liquid display module（LCD）to display. The software needs the cooperation of the mobile BB and the division code of multimedia chip to realize the processing of the coding, decoding and man-machine interface. |
