The video decoding method of calculation and motion vector data storage method of data

The present invention provides a video decoding method and a method of storing data calculating motion vectors, the video decoding method comprises setting a reference data storage tables in the frame queues static random access memory, to store the basic information of the plurality of reference frames in the reference frame queue table, each reference frame memory unit has a queue table index information corresponding to the reference frame within the decoder buffer; a plurality of sets of information in the frame buffer corresponding to the buffer stores the decoded index information, each set of frame buffer includes a frame display order information data, the motion vector storage address information; motion vector data is stored for each reference frame, the motion vector storage address information of storing the encoded motion vector data tree units corresponding block in the reference frame address information in the dynamic random access memory DRAM . The method of the present invention should be possible to improve the efficiency of video decoding, and save the hardware cost, and save the video decoder is occupied bandwidth resources.
