ABSTRACT:
A train of coded input picture data carrying moving picture information includes at least one picture data which need to refer to another picture data and at least one coded picture data containing an error. Such a train of input picture data is decoded with the influence of the error minimized and outputted in predetermined order by using a method including the steps of (a) upon detection of an error in a first input picture data in the train of input picture data, skipping the first input picture data and succeeding input picture data without decoding them until a second input picture data which need to refer to no reference to another picture data for decoding appears, and outputting consecutively a third picture data inputted before the first input picture data and already decoded, (b) decoding the second input picture data and outputting the decoded picture data after the third decoded picture data outputted consecutively, and (c) skipping picture data succeeding said second input picture data without decoding them until a fourth input picture data which need to refer to no reference to another picture data for decoding or a fourth input picture data which need to refer to the second decoded picture data for decoding appears, and outputting consecutively a picture data obtained by decoding the second input picture data.
