    摘要: A method for automatic detection of data types for data type dependent processing has two orthogonal classification systems defined, and determines for incoming data items a data type according to the first classification system and another data type according to the second classification system. The first classification system comprises the data types Essence (E), Metadata (M) and Container (C). The second classification system comprises the data types Physical Data (PD) and Abstract Data (AD). A default data type may be defined for data items not being uniquely classifiable. Advantageously, the inventive method can be used when different classes of data items require different methods for processing, e.g. content searching.

    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 “unselected”, “selected” or “activated”. According to the invention, the representation of a menu button may vary, depending on its state. An image or an image sequence, e.g. cartoon, may be associated to a buttons state, providing user animation. 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. A data structure is disclosed which allows storage of such menu data e.g. on a Blu-ray disc.

    摘要: Subtitling can be based on either pixel data or on character data. Character data allow very efficient encoding, but from character strings alone, subtitling can not be converted into a graphical representation to be overlaid over video. The intended character set, font and e.g. font size, must either be coded explicitly within the subtitling bitstream or an implicit assumption must be made about them. In pixel-based subtitling, subtitling frames are conveyed directly in the form of graphical representations by describing them as (typically rectangular) regions of pixel values on the AV screen, at the cost of considerably increased bandwidth for the subtitling data. According to the invention, a font memory is used that allows an efficient realization of pixel-based subtitle lettering, because the glyphs need only be transmitted once and thereafter are referenced by relatively compact character references during the AV event. Thereby the invention combines the advantages of pure pixel-based and pure-character-based subtitling schemes, while mostly avoiding their respective shortcomings.

    摘要: The gist of the invention is 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. The invention includes abilities for improved authoring possibilities for the content production to animate subtitles. For subtitles that are separate from AV material, the 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: 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: 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: 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.
