【Abstract】 This paper firstly analyzes the present status of the digitalized and Network based video surveillance systems and discusses the key technologies of embedded video surveillance server system. Then two categories of scheme for video surveillance server system, which are based on software MPEG4 encoding on DSP platform and hardware MPEG4 encoding on ASIC platform respectively, are introduced. Several typical systems in each category are presented in detail and the features of them are compared.更多还原
