| Abstract: | In order to satisfy video communication and smart video surveillance,MPEG-4 encoding technology was researched and a scheme of MPEG-4 video simple profile encoder IP was implemented based on FPGA.According to use classification and comparison methods,the MPEG-4 encoding technology was discussed in different kinds of applications specified in their implementations.Conclusions were dropped in the characteristics of different applications.In order to accelerate the efficiency encoded further,MPEG-4 video encoder was designed and implemented on FPGA.According to testing,the result was hoped. |
