<p>PROBLEM TO BE SOLVED: To provide a device for coding video such that a special buffer for determining whether or not the entire picture is to be skipped becomes unnecessary and the sequence of video is not reversed even if the entire picture is skipped. SOLUTION: A comparative determination means 125 compares a predicted amount of accumulation in the receiving buffer of this decoding device with a threshold set on each of picture types, on every single picture data before the picture data is decoded. The comparative determination means 125 determines that a coding processing of image data is to be skipped, making DCT means to stop the coding processing, when the predicted amount of accumulation in the receiving buffer is under the threshold. Further, the comparative determination means 125 produces the outputs of all skip pictures such that all remaining macro-blocks except the top and bottom of a slice layer in a skip picture storing memory 126 consist of the skipped macro-blocks.</p> |
