    摘要： The invention is related to a device for presenting, an image frame by help of a set of displaying commands wherein a displaying command comprises a displaying area and a displaying content.The device comprises means for adapting a first and/or a second displaying command set such that an adapted displaying command sets comprises displaying areas which do not intersect with any displaying area of the same set. Furthermore, the displaying areas of an adapted set cover a display area the image frames are displayed on. The device further determines displaying commands of the adapted second set not comprised in the adapted first set. Then, the determined displaying commands are executed.Adaptation makes comparison of displaying commands suitable for excluding areas from displaying/blitting/clearing.

    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： 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.

    摘要： An apparatus for reading from an optical recording medium, and more specifically to an apparatus suitable for reading from an optical recording medium having a high data density is proposed.The apparatus has: a light source for generating a first light beam; means for generating a second light beam, which has a different wavelength than the first light beam; one or more focusing means for focusing the first light beam and the second light beam onto the optical recording medium to form a first light spot and a second light spot, wherein the second light spot is larger than the first light spot and physically and/or virtually encompasses the first light spot; one or more detectors for detecting a first light beam and a second light beam reflected by the optical recording medium; and means for generating a data signal from the difference between the detected first and second reflected light beams.
