Abstract:

In order to meet the requirements of realtime video communication system, a new plan encoding the video data with H.264 and wireless transmission by streaming media technique was designed. To improve encoding speed, the system adopts S3C6410 own internal hardware coding module MFC (Multi Format Codec). We make a further research of H.264 video packet method and network transmission method based on RTP (Real-time Transport Protocol) protocol, finally by sending data to the receiver through Wi-Fi network H.264 video transmission based on C/S architecture is achieved. The test results show that the system meet the requirements of real-time video communications, the framerate of hard-coding is 30 frame/s with advantages of high proportion of video compression ratio and transmisson stability.
