Design Of Embedded Network Camera Based On RTP/RTCP

Nowadays, with the rapid development of multimedia technology and computer network and communication technology, it has presented a new trend in embedded video field that is downsizing, digital and networking. Aiming to this trend, a MPEG4 embedded network camera based on ARM processor and uClinux is introduced in this paper.In this paper, an embedded core board is realized first, which adopts Samsung's S3C2510A as embedded processor and uClinux as operating system which takes charge in controlling of system. The video and audio gathering circuit which adopts WIS's GO7007SB as core encodes high effectively and stably. A digital and networking video monitoring system is composed of abundant network function and extremely low power of ARM940T prosessor, conveniency of uClinux and high compressing of MPEG-4, and combination of applying of P2P and RTP protocol.The practice proves that this system is very high performace, low cost, powerful and stable.The development and application of video monitoring system and embedeed system are introduced firstly in this paper. A design scheme is presented by nailing down this paper's orientation and significance. Then two network protocols are introduced—RTP/RTCP protocol and P2P protocol. Based on this, we detail the implement of hardware and software separately. About software, we concentrate on the system software and application programming. Finally, we expatiate on the design and implement of video network transmiting based on RTP/RTCP and P2P and system testing. At last, this paper is summarized and the future work is presented.The main work of this paper could be summarized as follow:Hardware design of embedded network cameraThe implement of configuring and managing programmingControlling rotation of pan-tilt-zoomVideo network transmitting based on RTP/RTCP and flow controlThe implement of real-time communicating by the combination of applying of P2P and RTP protocol...
