  • Patent number: 7756398
    Abstract: A buffer initially preloads a text subtitle stream recorded on a recording medium. The preloaded text subtitle stream includes a dialog style segment and a plurality of dialog presentation segments. The dialog style segment defines a group of region styles and palette information. Each dialog presentation segment contains at least one region of dialog text, where each region of dialog text is linked to a selected one of the group of region styles defined in the dialog style segment. A text subtitle decoder reads a palette update flag included in each dialog presentation segment and presents each dialog presentation segment according to an indication of the palette update flag. The palette update flag indicates whether to use the palette information defined in the dialog style segment or to use new palette information when presenting each dialog presentation segment.

  • Patent number: 7725010
    Abstract: An apparatus for reproducing data recorded on a recording medium includes a pick-up unit, a local storage, and a decoder. The pick-up unit reads main data recorded on the recording medium, and the local storage stores sub data associated with the main data. The sub data may include interactive graphic streams or text subtitle streams. The decoder decodes the main data and the sub data using a PlayList which includes a main path and a sub path. The main path contains a PlayItem for play-back of the main data, and the sub path contains at least one SubPlayItem associated with the PlayItem for play-back of the sub data in association with the play-back of the main data. The PlayList file further includes sub path type information which indicates whether the SubPlayItem included in the sub path is synchronized with the PlayItem.

  • Patent number: 7693399
    Abstract: The present invention relates to method and apparatus of providing data stream together with program specific information (PSI) requisite for data stream selecting, separating, and decoding of a digital TV set. The present invention, when transmitting PSI to a digital TV set, measures time length of the PSI, creates time information preceding a transport time of the first TP belonging to data stream by the measured time length, converts PSI to at least one TP the created time information is added to, and transmits the converted PSI TPs before data stream TPs. Owing to the PSI provided along with a digital data stream, the digital data stream from a recording medium can be selected, separated, and decoded at a digital TV set without data loss. Furthermore, even though PSI is additionally provided, continuity among time information written successive TPs of PSI and data stream is always ensured.
