| 摘 要： | 在以数字多媒体处理器TMS320DM6467T为核心的视频处理平台VPC6467T上,基于可变参数的前向纠错(FEC)技术设计了一种通信系统。本系统的嵌入式视频发送端采用了ARM+DSP的硬件架构及Linux平台,接收端是PC的Windows平台。实验结果表明,所设计的系统实现了远距离通信时基于UDP协议的前向纠错编解码通信功能,可以有效地降低误码率,提高远距离视频传输的质量。

| Abstract: | Based on variable parameter Forward Error Correction technology, a communication system is designed on video processing platform VPC6467T with the core of TMS320DM6467T processor. The embedded video send terminal uses ARM ＋ DSP hardware structure and Linux platform, and the receiver is Windows platform of PC. Experimental results show that the system achieves UDP- based forward error correction communication, which effectively reduces the error rate and improves the quality of video transmission in the case of long distance communication. |
