Patent ID: 8306405

Claim:
A decoding method for decoding an AV stream by using a management information, wherein, the AV stream is managed as one file containing AV data, a file system management information for managing the AV stream and the management information as respective files, has already been recorded onto a recording medium, and the management information contains a first entry information being defined to correspond to a first section that can be reproduced consecutively in the one file, the decoding method, comprising: decoding, in a decoder, an AV stream by using management information, the file system management information first rewritten so that a second section is deleted from a first section in the one file that already has been recorded onto a recording medium in order to join points right before and right after the deleted second section in the one file and then the management information rewritten so that a first entry and a second entry is allotted before and after the point of junction, respectively in order to indicate a point of junction in the AV stream; and halting decoding of the AV stream at the point of junction indicated by the management information, wherein the management information manages a sequence of a consecutive AV data in the AV stream as a basic unit for managing the one file.
