Abstract
A system records an AV stream composed of a plurality of record units (RUs) containing independently reproducible video units (VUs) of at least video or audio and program information (Movie atom) managing the AV stream, onto a recording medium. The program information contains a piece of information (Edit list atom) that manages a point of junction between the record units or between AV streams. In decoding the AV stream, decoding is halted or decoders are switched at the point of junction, based on the management information on the points of junction, for example.
