摘要
针对传统DVS昂贵的成本等问题,提出了一种基于TVP5158和TMS320DM368处理器平台的多路DVS设计方案。通过对此平台进行硬件和软件设计,利用TVP5158从前端摄像头采集视频数据,再用ISIF模块从ITU656码流中分解出有效数据,使用DMA方式对4通道复合数据流进行分离,通过RESIZER将数据由422格式转换为420格式,最后使用HDVICP模块进行H264编码后完成网络传输。
This paper introduces a DVS system based on DM368 and TVP5158.TVP5158 is used to convert analog video to digital signal at first,then the valid video data is checked by ISIF module and the composite 4 channel digital videos are split- ted by DMA,after this,the RESIZER module is used to convert 422 video format to 420sp video format,at last,the raw video is encoded into H.264 stream by HDVICP module and sended by net.
