  • Patent number: 7949225
    Abstract: 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 b16 to b23 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.

  • Patent number: 7889620
    Abstract: A light source emits light with a first wavelength and light with a second wavelength longer than the first wavelength toward an optical disk from adjacent positions. An optical receiver detects light reflected from the optical disk. An astigmatism-generating element generates light used for focus control in a condition where a focusing position on one of two perpendicular cross sections including an optical axis of the light reflected from the optical disk is located ahead of the optical receiver and a focusing position on the other cross section is located behind the optical receiver are included. The astigmatism-generating element is a Fresnel mirror configured to include a plurality of reflecting mirrors. A level difference between the reflecting mirrors adjacent to each other is distributed in a range from a depth of substantially (natural number/2) times the first wavelength to (natural number/2) times the second wavelength.
