Abstract

AbstractThe technology of high-definition(HD) video wireless transmission enables users to get rid of the shackles of cable, displaying real-time video information through PC and other intelligent terminal. In this paper, it is focused on analyzing the characteristics and key technology on mesh network as well as the methods of guaranteeing the quality of HD video. Using TMS320DM368 processors as a core processing chip, and video acceleration coprocessors to complete H.264 video coding. Real Time Streaming Protocol packages the compressed video stream, EMAC module composes mesh network with multiple Wi-Fi AP, which achieve the work of wireless transmission for 720P HD video.KeywordsHD videoWireless transmissionMesh network
