Abstract
In a picture signal decoding method, preceding of the display operation to the decoding operation can be prevented as to a bidirectional predictive picture. When the user specifies an arbitrary magnification display mode in which a part of a decoded picture is magnified to an arbitrary size and displayed on a display screen, the decoding operation of an input picture signal which corresponds to a bidirectional predictive picture in input picture signals is started from a signal portion corresponding to the input display start position. Thereby, a picture signal decoding apparatus in which decoding operation can always be finished before display operation starts, can be accomplished with a simple construction.
