    摘要： Subtitling aims at the presentation of text information and graphical data, encoded as pixel bitmaps. The size of subtitle bitmaps may exceed video frame dimensions, so that only portions are displayed at a time. The bitmaps are a separate layer lying above the video, e.g. for synchronized video subtitles, animations and navigation menus, and therefore contain many transparent pixels. An advanced adaptation for bitmap encoding for HDTV, e.g. 1920.times.1280 pixels per frame as defined for the Blu-ray Disc Prerecorded format, providing optimized compression results for such subtitling bitmaps, is achieved by a four-stage run length encoding. Shorter or longer sequences of pixels of a preferred color, e.g. transparent, are encoded using the second or third shortest code words, while single pixels of different color are encoded using the shortest code words, and sequences of pixels of equal color use the third or fourth shortest code words.

    摘要： A method for optimizing a scheduler for an optical pick-up reduces switch times required for seamless video angle switching. The pick-up reads data streams from different files on an optical storage medium, e.g. Blu-Ray disc. Seamless video angle switching requires reading and buffering a new video data stream from another file, delaying the switch to be visible. Labels that mark entry points for seamless angle switching are attached to the video stream, and are stored together with the video data in a buffer. When an angle switch is requested, and thus a switch to a new video data stream, the scheduler determines the time before data from the new data stream can be buffered, detects the next label, and stores the new data beyond the label, thus flushing non-relevant parts of the previous buffer contents.

    摘要： Embodiments of the invention include a subtitling format encompassing elements of enhanced syntax and semantic to provide improved animation capabilities. The disclosed elements improve subtitle performance without stressing the available subtitle bitrate. This will become essential for authoring content of high-end HDTV subtitles in pre-recorded format, which can be broadcast or stored on high capacity optical media, e.g. the Blue-ray Disc. Embodiments of the invention include abilities for improved authoring possibilities for the content production to animate subtitles. For subtitles that are separate from AV material, a method includes using one or more superimposed subtitle layers, and displaying only a selected part of the transferred subtitles at a time. Further, colors of a selected part of the displayed subtitles may be modified, e.g. highlighted.
