    摘要: The resistance against recording defects of a write-once optical disk is enhanced allowing realtime recording and playback of data streams with a single speed disk drive. A data stream is recorded in data blocks on the optical disk. An error correction block for one or more data blocks is generated and written on the same optical disk during recording. A spare data area is kept blank on the storage medium and used for storing a defect data block reconstructed by using the error correction block.

    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: A method for generating an interactive electronic menu on a display, the menu comprising menu items, wherein a menu item may be in a deselected, selected or activated state, and the menu being coded into a menu data segment, comprises that at least a first and a second menu item are connected by a parent-child relationship, wherein the second menu item being a child of the first menu item can only be selected when the first menu item is selected, and further comprises that the first and the second menu item are coded into the same data segment. The method is preferably usable for menus relating to content of digital storage media, such as optical discs, in particular read-only Blu-ray discs.

    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: 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. 1920×1280 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.
