【摘要】：针对大量视频数据信息传输中延时、卡顿的问题,设计了一种以TMS320DM6467处理器为硬件核心,Windows操作系统为软件核心的视频压缩与传输系统。系统采用CCD摄像头以及解码器TVP5150完成视频的采集。运用H.264视频编码技术实现了视频的实时压缩,利用RTP协议将采集、压缩编码完成后的视频数据通过局域网发送至上位机,对VLC配置后可接收传输的视频流。在保证视频清晰度的条件下,系统测试结果显示:视频实时性高,网络传输视频的速度满足视频监控的需求,可以获得大于150的压缩比。
[Abstract]:A video compression and transmission system based on TMS320DM6467 processor is designed to solve the problem of delay and delay in the transmission of video data. The system uses CCD camera and decoder TVP5150 to complete video acquisition. The real-time compression of video is realized by using H.264 video coding technology. The collected and encoded video data are transmitted to the host computer via LAN using RTP protocol. The video stream can be received and transmitted after the configuration of VLC. Under the condition of ensuring video clarity, the system test results show that the video real-time is high, the speed of video transmission can meet the need of video monitoring, and the compression ratio of more than 150 can be obtained.
