Abstract

When a segment of a compressively coded stream of moving-picture data is rendered unusable by an error, usable decoded data are discarded in a range adjacent to the unusable segment, to avoid picture defects that might result from the use of incorrectly decoded data. The discarding range may extend from one end or from both ends of the unusable segment. When the data are coded in two or more different modes, two or more corresponding ranges of different lengths may be set.
