| Abstract: | To meet the request of high definition and processing of video in security monitoring, this article develops an IP camera based on dm368 and embedded Linux. Hardware design is put in details, consisting of codec, memory, transmitting and power supplying modules. The sampled video stream compressed and encoded by the protocol of h.264 can be transferred in the network follow the protocols of RTP and RTCP. The stream is decoded and displayed by the software in the host computer. Tips of timing and EMC design for PCB layout are mentioned for reference |
