摘要
从硬件和软件上论述了如何在手机平台MTK系统上实现CMMB功能的方法,详细论述了硬件模块结构和软件的实现,以手机常见平台MT6225为通信模块搭配强大的多媒体芯片TCC7690,解调芯片IF201,将音频信号通过D/A转换器件WM8371传送到发声设备,图像直接由多媒体芯片传给液晶显示模块(LCD)显示。软件需要手机基带(BB)和多媒体芯片部分代码共同配合实现解码以及人机界面的处理。
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.
