| Abstract: | In this paper,a top-level decoding architecture compatible to various video coding standards is proposed.The design is targeted at a low-cost hardware video decoder implementation.The top-level reusable mechanism is analysed based on the four areas,including the top-level video decoding architecture,syntax element parsing,reference frame management and stream buffer management.At last the specific design and implementation is verified by c model. |
