  • Method of storing decoded video data, method of computing motion vector data and computer device
    Patent number: 10819995
    Abstract: The present invention provides a method of storing decoded video data, a method of computing a motion vector and computer device. The method of storing decoded video data comprises: setting a reference frame queue table in a static random access memory and storing basic information of a plurality of reference frames in the reference frame queue table, wherein each unit of the reference frame queue table stores corresponding index information of one reference frame in a decoding buffer; storing a plurality of groups of frame buffering information corresponding to the index information in the decoding buffer, wherein each group of frame buffering information includes frame display order data and motion vector storage address information; and storing motion vector data of each reference frame in a dynamic random access memory.

  • Variable frame rate encoding method and device based on a still area or a motion area
    Patent number: 10742989
    Abstract: A variable frame rate encoding method applied to a video encoder, and the method, by obtaining a current coded macro block: determining whether the current coded macro block is located in a still area and if the current coded macro block is located in the still area, encoding the current coded macro block by using a first preset coding mode, and if the current coded macro block is located in a motion area, then encoding the current coded macro block by using a second preset coding mode.
