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.
Claims17
A data recording method for recording a second unit composed of a plurality of first units containing first data having at least video and first program information that contains positional information as to the first units, onto a recording medium,
- characterized in that the first data is encoded data based on a MPEG standard, the second unit is managed by a single file, and the first program information contains information showing a point of junction between the first units in the file.
(Cancel)
A data editing method for producing a second unit by connecting first and third units each containing first data having at least video,
- characterized in that the first data is encoded data based on a MPEG standard, the second unit is managed by a single file, and first program information contains positional information as to the first and third units, and the first program information contains information showing a point of junction between the first unit and the third unit in the file.

(Cancel)
A data decoding method for decoding a second unit composed of a plurality of first units containing first data having at least video, in accordance with first program information that contains positional information as to the first units,
- characterized in that the first data is encoded data based on a MPEG standard, the second unit is managed by a single file, the first program information contains information showing a point of junction between the first units in the file, and decoding of the first units is halted at the point of junction.
A data decoding method for decoding a second unit composed of a plurality of first units containing first data having at least video, in accordance with first program information that contains positional information as to the first units, characterized in that the first data is encoded data based on a MPEG standard, the second unit is managed by a single file, the first program information contains information showing a point of junction between the first units in the file, and decoders are changed over before and after the point of junction.
(Cancel)
