REPRODUCTION DEVICE, PROGRAM, AND REPRODUCTION METHOD

摘要

PROBLEM TO BE SOLVED: To provide a reproduction device which harmonizes a user's wish to enjoy subtitles displayed in many languages with a maker's realistic demand to keep a guaranteed quality of a product even when displaying text subtitles. SOLUTION: PSR 48-61 contain a plurality of Decode Capability flags. Each of the flags indicates by its set value the presence/absence of decode capability of the text subtitle for each language. A Procedure execution unit 20 refers to the set value of each flag in the PSR 48-61 and determines whether each of the text subtitle streams can be displayed. A stream selection unit 17 selects the text subtitle stream which has been determined to be displayed. The b16 to b23 of a PSR 30 contains a permission flag, which indicates whether to permit the stream selection part 17 to select an unsupport language which is a language having rendering capability but having no support capability.
