Video encoder is an important part of video network surveillance system, and its design goals include combining real time coding, high performance, low cost and flexible control with small size. To meet all these requirements, DSPs with video ports provide an ideal solution. In this paper, we've designed and implemented a Blackfin DSP-based, high performance, low cost, low power consumption, real time network video encoder. The hardware system, software flow, algorithm optimization, Ethernet transmission and performance test are discussed in detail. This network video encoder has been successfully used in our MPEG-4, H.263 network video surveillance system
