Embodiment Construction
[0033] The video decoding data storage method of the present invention is applied in the video coding and decoding technology of the H.265 standard. By setting a special reference frame queue table, each unit in the table corresponds to the data in the decoding buffer zone one by one, thereby reducing the dynamic The amount of data read from the random access memory improves the efficiency of video decoding and also reduces the area of the integrated circuit. The calculation method of the motion vector data is to realize the calculation of the motion vector data based on the data stored in the above video decoding data storage method, so as to return the calculated motion vector data.
[0034] Embodiment of video decoding data storage method:
[0035] In the HEVC standard, after each frame of data is decoded and displayed in the display order, some frames will not be used as reference frames and will be discarded, but many frames will be used as reference frames for other fr...
