The Design Of Wireless Video Surveillance Based On Davinci Platform

Nowadays world science and technology are developing rapidly and the video-surveillancemarket is growing faster and faster, video surveillance based on the internet protocol networktransport is coming to broad use in the near future.In view of this kind of situation, in order to promote the development of ip camera market, weintroduced a video surveillancesystem based on TI TMS320DM365chip.In this paper the main work to be completed are: embedded system hardware reframe,embedded system software design, network video stream protocol design, and system debuggingand testing.The embedded system hardware design is based on TMS320DM365include the clock circuit,memory circuit, ethernet circuit, USB circuit, communication circuit, and the power circuit, etc.The embedded system software design is aiming to realize the wireless video surveillance andthe host’s acceptance, then achieves the flow control of the wireless video.Networking transmitting protocol can accomplish reliable transmissionmechanism and videoflow control mechanism, which guarantees the one-way control between user and the video hostfront-end.Video encoding and data rate can realize the standard video resolution of H.264encoding andpackagelize data rate accord to user datagram protocol and then pass through the wireless video viathe WIFI.The video reveivance software on the PC platform can realize the in-going network video flowfrom the pc port eighty and unpackagelize the encoded data rate from the network packages and italso accomplish the realtime video display on the platform.At the end of this paper, it summarizes the finished work of the subject and the existingshortage. At the same time, it looks forward to the future development of the video communicationtechnology and analyzes the future work and improvement to perfect this subject.
