Abstract
A method, apparatus and computer program for detecting a scene change point in a moving picture which has been coded according to a moving-picture coding process. The moving picture coding process divides the processing picture into a plurality of pictures. Each picture is divided into a plurality of blocks each being compressed by an encoder. The encoder operates according to a selected one of three compression techniques, namely an intra-picture compression technique, a differential-picture compression technique or a skipped-block compression technique. The invention counts the number of blocks of each picture subjected to the compression techniques, records the counts as user data, and analyzes the counts stored in the user data in a decoding operation in order to detect a scene change point of the moving picture.
