Abstract
A BD-ROM playback apparatus plays back a text subtitle stream during a playback of moving pictures. A reserved area of a PSR stores therein, as a supplementary language, an identifier of a language in which the playback apparatus is not capable of decoding a text subtitle stream, due to inconvenience caused during display of the text subtitle.The set-up unit 32 inquires of a user whether the user wishes to increase the number of languages in which subtitles are displayable even if inconvenience may be caused during the display. In the case where the user performs an affirmative operation in response to the inquiry, the stream selection unit 17 selects a text subtitle stream corresponding to the supplementary language from the plurality of text subtitle streams.
