    摘要： A method and apparatus for updating motion vector memories used for prediction of motion vectors in a video compression coding/decoding method and system. For a frame composed of N macroblocks in the horizontal direction, only (2N+1) motion vector memories are used to store all motion vectors necessary to motion prediction, and only three memories per macroblock are used to update motion vectors, thereby reducing the size of a circuitry, the amount of computation and the amount of power consumed.

    摘要： A method for coding a digital interlaced moving video. Picture-unit overhead information is first transmitted and it is then determined whether a video packet to be coded is a first packet of a given picture. A video packet header including overhead information for an interlaced decoding operation is transmitted if the video packet is not the first packet of the given picture. If the video packet is the first packet of the given picture or after the video packet header is transmitted, it is determined whether the given picture is an intra picture. If the given picture is the intra picture, the video packet is coded and transmitted in an interlaced intra picture manner. The video packet is coded and transmitted in an interlaced inter picture manner if the given picture is not the intra picture. If the video packet is not a last packet of the given picture, a digital interlaced coding operation is repeatedly performed. The digital interlaced coding operation is ended if the video packet is the last packet of the given picture. Even when the coded, interlaced moving video is transmitted through a channel where a transmission error may often occur, such as a mobile communication channel, a decoder can perform an error concealment operation of high performance to reconstruct a moving picture of high quality.

    摘要： A method and an apparatus for predictively coding shape information of a video signal. An error between the current shape information and the previous shape information is obtained through the comparison therebetween. If the obtained error is greater than or equal to a predetermined reference value, the current shape information is coded. However, in the case where the obtained error is smaller than the predetermined reference value, the current shape information is reconstructed using the previous shape information. Therefore, a time-axis redundancy of the shape information is removed to prevent the transmission of unnecessary information, resulting in an increase in compression coding efficiency.

    摘要： A method for coding a digital moving video including gray scale shape information. Picture-unit overhead information is first transmitted and it is then determined whether a video packet to be coded is a first packet of a given picture. A video packet header including overhead information for the decoding of the gray scale shape information is transmitted if the video packet is not the first packet of the given picture. Then, it is determined whether the given picture is an intra picture. If the given picture is the intra picture, the video packet is coded and transmitted in an intra picture mode. If the given picture is not the intra picture, the video packet is coded and transmitted in an inter picture mode. If the video packet is not a last packet of the given picture, a digital moving video coding operation is performed repeatedly. The digital moving video coding operation is ended if the video packet is the last packet of the given picture. Even when the coded video packet is transmitted through a channel where a transmission error may often occur, such as a mobile communication channel, a decoder can perform an error concealment operation of high performance to reconstruct a moving picture of high quality.
