数字电视编码器测试系统

Design and Implementation of Digital TV Encoder Testing System

针对当前数字电视编码器测试系统短缺的情况 ,提出了一种兼具通用性和灵活性的数字电视编码器测试系统的方案。该测试系统基于工控机的 PCI总线开发 ,最高传送测试码流速率达 2 7Mbyte/s。该测试系统在高清晰度电视编码器的调试中发挥了重要的作用 ,并可用于其他类型的数字电视编解码器的测试。

Aiming at the deficiency of the digital TV encoder testing system, a hardware design and the implementaion of the testing system are presented. This system is developed based on PCI bus, to tranfer and receive data, and the fastest transferring data rate is 27 M Byte/s. The testing system can be used to test many kinds of digital TV encoders.
