摘　　要：针对远程视频监控中视频清晰度不高、实时性不佳的问题.结合高度集成的数字媒体处理器达芬奇的应用,设计了以TMS320DM6467T处理器为硬件核心,Windows系统为软件核心的HDMI高清视频的采编器.采用1080p高清数字摄像头以及SII9125解码驱动芯片完成高清视频的采集;运用H.264视频编码技术实现了视频的高度压缩;并将压缩后的视频实时传输到监控中心,同时存入硬盘文件系统.系统测试结果表明,视频实时性高,存储后的数据可以获得大于100倍的压缩比.For remote video surveillance video is not high definition, real-time problem of poor. Combined with highly integrated applications DaVinci digital media processors designed to TMS320DM6467T processor core hardware, Windows system software, the core of the HDMI high-definition video editing device. Using a digital camera and 1080p HD decoding SII9125 driver chip to complete high-definition video capture; using H. 264 video encoding technology enables highly compressed video; real-time transmission of video and compressed to the monitoring center, while stored in the hard disk file system. System test results show that： high real-time video, data storage can be obtained after more than 100 times the compression ratio.
