摘要： Removable media such as optical discs may carry valuable audio-visual data representing movies or the like, which are sold by content providers or studios. To prevent pirate copies, data on these media are often encrypted for copy protection. This copy protection may use a disc specific electronic decryption key, which is stored on the disc itself. Supplementary data such as games, subtitle or audio streams that are regarded as being closely related to disc contents, but are not stored on the disc itself, are encrypted so that decryption is only possible with a decryption key retrieved from the disc, or in particular the same decryption key that is used for the disc contents. The method is particularly effective for copy protection or cross usage exclusion of supplementary data when the decryption key is prevented from being accessible to the user.

摘要： Multimedia content of exchangeable storage media, such as optical discs, may be extended by bonus content that is downloaded via Internet connection and stored on a local storage device. An improved method for integration of different menu items relating to on-disc content and downloaded content provides flexibility and a simple, low cost solution. The method for integration of downloaded bonus content into a menu comprises defining one or more placeholders within a menu, determining a storage location or naming convention for bonus content, declaring for each placeholder an attribute providing a unique association to a specific type of bonus content, providing a button image, detecting presence of bonus content data, replacing the associated placeholder by the associated button image and enabling an associated action to be taken when said button is selected.

摘要： Playback devices, e.g. DVD players, for removable mass storage media used for the distribution of multimedia content contain a lot of firmware to control its functions. Typically, such firmware may be updated several times during the lifetime of the device. For playback devices that are already at a consumer's site and cannot be updated online, it is possible to update the firmware without using separate media, such as update-CDs, by storing firmware update data on removable storage media such as DVDs or Blu-ray discs that contain primarily audio-visual contents. Thus, it is possible to utilize unused storage space on e.g. optical discs, and to distribute and install firmware updates easily without requiring separate media or technical knowledge of the user.

摘要： MPEG video uses motion compensated prediction for coding pictures. A GOP includes at least one intra-coded picture to start decoding with and a number of inter-coded pictures and normally also includes bi-directionally predicted pictures. However, the GOP structure is not constructed for playing GOPs in backward direction in a trickplay mode across GOP boarders. The invention facilitates, for different GOP structures, a smooth backward video mode thereby reducing the required number of frame buffers and achieving near real-time speed presentation. In some embodiments some I and/or P pictures are decoded more than once. The invention also allows backwards decoding of MPEG-4-AVC GOPs including B-stored pictures.

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： Optical storage media often contain data structures for a menu suitable for selection of a title, a chapter, a parameter or others. Such menus usually comprise a number of buttons to be displayed, with each button having a state. Possible states of buttons are e.g. “unselected”, “selected” or “activated”. According to the invention, the menu may contain buttons that can be selected through the keys on the remote control, but that don't have any images or text associated. This allows creating “invisible buttons” that automatically execute commands upon selection. Further, a sound or sound sequence, e.g. melody or click, may be associated to a buttons state, and may be played back when the button enters this state. Such menu data may be stored e.g. on a Blu-ray disc.

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.
