REPRODUCTION DEVICE, PROGRAM, AND REPRODUCTION METHOD

摘要

A BD-ROM playback apparatus for selecting and playing back one among text subtitle streams together with a moving picture. PSR 48 - 61 store Decode Capability flags whose set values indicate, for each language, whether or not a decode capability is present. Procedure executing unit 20 judges whether each text subtitle stream can be displayed, by referring to each set value of flags. Stream selection unit 17 selects a text subtitle stream judged as being able to be decoded. Here, the decode capability for a language being present indicates presence of rendering capability for converting character codes of the language into bitmaps, and support capability for supporting properties of the language. The b 16 to b 23 in PSR 30 includes a permission flag indicating whether stream selection unit 17 is permitted to select an unsupported language for which rendering capability is present but not support capability.
