Data recording method, data editing method, data decoding method, and apparatus and recording medium therefor

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.

         16 . A data recording method for recording
 an AV stream containing at least video data,   program information as to the AV stream, and   filesystem management information for managing the AV stream and the program information as respective files, onto a recording medium, wherein   the AV stream is managed as a single file, and   the program information contains first track information corresponding to a first section that is capable of reproducing consecutively in the AV stream,   the method comprising the steps of:   deleting a second section from the first section,   first rewriting for rewriting the filesystem management information so that the points right before and right after the deleted second section are jointed in the AV stream, and   second rewriting for rewriting the program information in such a manner that different tracks information are allotted before and after the point of junction, in order to indicate the point of junction.
