An information recording medium configured to have, in a region in which a main stream is recorded, a region in which at least one of subsidiary video data and subsidiary audio data packed after identification information has been assigned thereto is recorded.
An information reproducing apparatus for reproducing an information recording medium having a region in which at least one of subsidiary video data and subsidiary audio data packed after identification information has been assigned thereto is recorded in a region in which a main stream is recorded, the apparatus comprising:
- a reproducing section configured to read the main stream from the information recording medium and to apply a decode processing operation to at least one of video data and audio data packed after identification information included in the main stream has been assigned thereto;
- and
- a storage section configured to store at least one of the subsidiary video data and subsidiary audio data packed after identification information included in the main stream read from the information recording medium has been assigned thereto during a decode processing operation using the reproducing section.
An information reproducing method for reproducing an information recording medium which has a region in which at least one of subsidiary video data and subsidiary audio data packed after identification information has been assigned thereto is recorded in a region in which a main stream is recorded, the method comprising:
- a reproducing step of applying a decode processing operation to at least one of video data and audio data packed after reading the main stream from the information recording medium and identification information included in the main stream has been assigned thereto;
- and
- a storing step of storing at least one of the subsidiary video data and subsidiary audio data packed after identification information included in the main stream read from the information recording medium has been assigned thereto during a decode processing operation by the reproducing step.
