Inter-frame coding apparatus for video signal
专利汇可以提供Inter-frame coding apparatus for video signal专利检索，专利查询，专利分析的服务。并且An input video signal on line (1) is fed to a motion compensation inter-frame coder (5) which includes a motion detector and produces a motion vector on line (6b) and a prediction error on line (6a). A refresh timing circuit (2) causes purely spatial refreshing, e.g. by previous value difference coding, in a band of lines, which band shifts progressively through the frame. In order to avoid replication of errors by the refresh operation, an inhibit signal on line (4) causes the motion compensation to be prevented in the band of lines which has just been refreshed. The various signals are coded by a coder (9) for transmission to receiving decoders (11, 15). In a modification, the motion vector used in the coder (5) is not passed to the coder (9) for transmission. At the receiving end it is locally created in the decoder (15). Inhibition of motion detection is effected in the coder (5) by setting the motion vector to zero.，下面是Inter-frame coding apparatus for video signal专利的具体信息内容。
