信息时代对于视频通讯的需求越来越广,从较低码率的可视电话、视频会议、实时监控到高码率的空中侦察、数字电视等,迫切要求将高效率、高质量的视频压缩算法实用化。MPEG-4于2000年正式成为国际标准并不断地扩展。它不仅支持码率低于64kbps的多媒体通信,还能支持广播级的视频应用。与以前的视频标准相比,MPEG-4可以提供更高的压缩效率、更好的交互性以及更强的抗误码能力。目前,MPEG-4已经成为视频压缩标准的主流。……

设计并实现了一种基于TMS320C64x系列高性能通用DSPs的MPEG-4SimpleProfile编码器。详细介绍了系统的硬件结构和工作流程。为解决高分辨率视频编码的实时性问题，采用预测技术的运动估计计算法以及基于C64xCPU的软件优化技术。实验结果表明编码器对D1分辨率（720×576）视频的编码速率达到25帧/秒以上，且具有较低的码率和较好的图像质量。……
