    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 comfortable method and device for searching databases are required. Thus, a database access concept including an interface descriptor is proposed. The interface descriptor may be a XML-file which describes interface categories and database access strategies. The database interface machine may comprise a standard category display method and a standard database access method. The database interface machine can use the definitions contained in the interface descriptor to set up a categorized interface to the database and to perform complete database searches.

    摘要： A method for handling defects on a recording medium which deteriorate an adaptive bit recovery process is proposed. The method for handling defects on a recording medium during bit recovery from the recording medium, whereby a data stream read from the recording medium is processed by an adaptive bit recovery means, includes the steps of: storing fallback values for the adaptive bit recovery means a fallback register during processing of the data stream and updating the adaptive bit recovery means with the stored fallback values for recovering from an incorrect adaptation or for restarting after processing of a defect.

    摘要： A method and an input-output device are proposed for rendering content. Further, a servicing device is proposed for delivering pre-rendered content.For rendering, a portion of processing or memorizing resources of said input-output device is allocated such that remaining resources of said input-output device are sufficient for maintaining the input-output capability of the device. Then, it is determined that an amount of resources required for rendering exceeds the allocated resources and a corresponding degree of pre-rendering is determined, too. On the serving device, pre-rendering of the content according to the determined degree is performed and the pre-rendered content is delivered from the serving device to the input-output device.Since server-side rendering is limited to a required degree, bandwidth constraints can be met more easily. Furthermore, rendering occurs more distributed and can be adjusted dynamically, thus, response time can be reduced.

    摘要： The present invention relates to a redundancy protected mass storage system with increased performance, and more specifically to a mass storage system with multiple storage units. According to the invention, the resources that are essentially provided for compensating the damage of one or more storage units are also used to enhance the system performance. For this purpose during reading or writing the storage system just waits for the responses of a minimum number of required storage units to start reading or writing, respectively.
