The Software Design Of High Definition IP Camera Based On DM368

As society continues to digitizing and networking, as well as people generally increase in safety awareness, video surveillance industry has developed extremely rapidly in recent years. The high-definition IP Camera has many advanced features, such as it is interactive and the resolution of its image is very high, further more, which can carry out intelligence analysis to the image or video, so the high-definition IP Camera arouses a high degree of more and more security vendors and users' attention. It will become a hot in video surveillance industry.High-definition IP Camera can capture audio and video stream and perform optimization to it by video stabilization, video noise filter, lens distortion correction and so on. Then the audio and video stream will be coded and sent to Ethernet. People can view the real-time video easily without any restriction, such as time, place and quantity. high-definition IP Camera implements remote surveillance with high quality and efficiency.High-definition IP Camera system can do real-time transmission to high-definition video efficiently, and it can realize motion detection, face recognition and other smart analysis capabilities. In addition, it allows users to interact with it by the browser, thus users can do flexible configuration to the system for the related parameters of network, image and so on. In the text, we will research the software of the high-definition IP Camera to realize afore-mentioned functions. This research mainly based on DM368 that is the latest digital media system on chip of TI, with the operating system platform of MontaVista Linux. There are following specific work in the study. First, it completes the design of the overall framework of high-definition IP Camera system for the above functions, then implements the detailed design of the audio and video service module, the network transmission module, the system service module. Finally, it carries out the functional and performance test for these modules. The results show that the system can optimize the audio and video stream which have been captured, then codes it and transmits the compressed stream to the network. PC on the network can visit high-definition IP Camera with a browser, and the user can set the system parameters according to their own needs with the web.
