| 摘 要： | 为了解决标准清晰度监控系统中存在的一些问题,设计了一个基于TMS320DM365的高清视频压缩系统。采用ITU-T的H.264(DM365内嵌硬件压缩器)视频压缩算法,高清模拟视频信号通过专用视频解码芯片TVP7002转换成数字视频信号,在DM365中进行数据压缩,内嵌ARM把数据打包后传到internet,通过PC机软件解码,进行视频播放。实践证明,本编码方案很好的完成了数据压缩及传输,符合设计要求。

| Abstract: | To solve the existing problems of SD Surveillance system,this article develops a DM365 based system for video compression.The video compression algorithm adopt the ITU-T H.264(embed hdvicp).The video source is decoded to digital video data in the video decoder chip TVP7002,Then the digital video data are processed with HDVICP in DM365.The composed data are transmitted to the internet by the ethernert interface of the ARM,the stream is decoded by the software for displaying in the PC.The test results show that:the aviable and applicable scheme of H.264 video encoding implements the video compression and network transmission,attain the design demands. |
