Abstract:
A playback apparatus includes an obtaining unit obtaining playback management information including a main playback path of a main stream set, a first sub playback path of a first sub-stream set, and a second sub playback path of a second sub-stream set. The first and second sub playback paths are allowed for a predetermined category. A selection-receiver receives a selection of streams as a first combination or a second combination. A reading unit reads the corresponding stream sets according to whether the first or second combination is selected. A playback unit plays back the main stream set and the first or second sub-stream set. The number of files that are readable at one time is predetermined. The sub playback paths are determined so that the number of the files that are readable at one time does not exceed the predetermined number.
