H. 264/AVC advanced video coding with the feature of high compression ratio and complicated algorithm has applied widely at present,it broughts huge challenge to the design and verification of video decoder system. Based on the H. 264/AVC video decoder archi-tecture,in view of the complexity of decoder system,a verification system is presented,also introduce a multiform and multilevel verifica-tion policy which can be implemented during the each stage of decoder design. According to the feature of RTL virtual platform,FPGA prototype platform and post-sim platform,respectively program different test pattern,forming test plan based on the decoder finally. The test plan proposed can be referenced by H. 264/AVC decoder which is similarity to the DUT mentioned.
