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 generating an on-screen menu comprising menu buttons and other menu items, e.g. help text, comprises one or more groups of menu buttons or menu items are defined, wherein a group comprises one or more menu buttons or menu items and has associated a defined area on the screen. A state is assigned to a button, the state being “enabled” or “disabled”, wherein only an enabled button or item may be displayed, and wherein within a group not more than one button or item may be enabled. The state of a button can be changed by commands associated with other buttons.

摘要： Optical discs may support “Out Of Multiplex” formats, meaning that different presentation components, like video, audio and subtitles, are stored on different files on the disc, e.g. Blu-ray discs. The different data streams are read by a single pick-up, requiring frequent pick-up jumps and extensive data buffering. The method for operating a scheduler for an optical pick-up reduces the number of pick-up jumps while optimizing the required buffer space. The scheduler is based on a static schema, meaning that the buffer for the data stream with the highest data rate is of minimal size, and therefore refilled in short periods while the buffers for the lower rated streams are dimensioned such that they can be refilled in multiples of the short period. Deviations from the static schema may be allowed, e.g. due to multi-angle video technique. Afterwards the scheduler returns to the original schedule.

摘要： Several data streams contain video, audio and/or other data. Some of the data streams are pre-recorded in a multiplex on a storage medium while other data streams are located out of the data stream multiplex on the storage medium. The data streams are synchronized using a navigation file (List_of_PlayItems), which comprises descriptors (PlayItems, SubPlayItems) pointing to parts of said data streams, wherein said descriptors define the arrangement in time for said data streams by means of data sub stream paths.

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.
