Title Transmission Application Design of Video Network Based on DM365
Abstract With video decoding technology and the increasing development of network communications, real-time video transmission has been more attention. When the video show the growing importance of real-time transmission and increasingly in life, it also plays an important role. Firstly, in the study of learning real-time transport protocol (RTP), Real-time Transport Control Protocol (RTCP) and Real Time Streaming Protocol (RTSP) and H.264 video coding standard and other relevant content, and then analyzed in the laboratory focuses on the hardware platform provided by the structure TMS320DM365 and functions, and the preparation of transmission applications design of video network based on TMS320DM365, and finally, the hardware platform to build successful completion of software applications on the basis of the preparation for the laboratory tests on the environment, and the results of the experiment phenomena would make a summary, and the corresponding technology vision for the future.
