中国移动多媒体广播(CMMB)测试接收机的设计与实现

China mobile multimedia broadcasting test receiver design and implementation

为了加快CMMB的推广和应用,全面评估CMMB网络的性能,尤其是测试CMMB的移动接收效果和城市覆盖效果,文中提出了一种基于CY7C68013A芯片的CMMB网络测试接收机的设计方案。本方案采用CY7C68013A芯片为控制核心,利用CY7C68013A芯片的GPIO口模拟的I2C、SPI总线通信接口和USB接口与PC机通信等技术,实现了CMMB信号参数存储、读取与CMMB码流播放同步进行的功能。

In order to speed up the promotion and application of CMMB,Comprehensive evaluation CMMB network performance,Especially test of the reception and CMMB mobile city cover effect,This paper Proposed one kind based on the CY7C68013A chip CMMB network test receiver design This project adopts CYTC68013A chip as the core control,make use of GPIO of CY7C68013A chip analog I2C,SPI bus communication interface and USB interface and PC communication technology, Implementation of the CMMB signal parameter memory,read and CMMB play stream synchronization function.
