Data Transmission and Processing of DTTV USB Testing Receiver in China

本文介绍了利用USB2.0和CY7C68013芯片开发USB接口通信系统的基本过程,介绍了使用DirectShow开发多媒体播放系统的基本流程,并且介绍了如何将上述两种技术结合起来,开发国家地面数字电视广播USB测试接收机的数据传输和处理系统。

Analysis and processing of bit stream have great meaning in signal coverage testing during construction of DTTV network. With high speed and universality of the USB2.0 interface, data stream created by receiving terminal is transmitted to a computer to be analyzed and post-processed. And that is helpful to development of a DTTV testing system. This article introduces how to combine USB2.0 and DirectShow to develop data transmission and processing system of DTTV USB testing receiver.
