    摘要: A method for modifying data read from read-only media during playback time comprises logically merging the on-disc directory tree and an associated off-disc directory tree. A logical directory tree is constructed from the data retrieved from the read-only medium, wherein the structure of the logical directory tree is identical with the structure of the directory tree of the medium. The method allows replacing content on the disc through downloaded content, e.g. replacing an out-dated trailer stored on the disc through a downloaded trailer for a new movie. The method further allows complementing or upgrading content on the disc, e.g. by downloading a new subtitle track from the internet.

    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: A method for optimizing a scheduler for an optical pick-up reduces the pick-up jump frequency and the initial start-up time for reproduction. The pick-up reads data streams from different files on an optical storage medium, e.g. Blu-Ray disc, and buffers the data streams in separate buffers, e.g. for video, audio and subtitles. Buffer sizes are optimized when the video buffer is as small as possible, i.e. large enough to bridge the pick-up access and read times for the other streams, and the buffers for the lower rated streams are extended such that the pick-up access frequency for lower rated streams is an integer multiple of the pick-up access frequency for the highest rated stream, usually the video stream. Initial start-up time is minimized by filling the buffers initially only to a minimum required level.

    摘要: The present invention relates to a method for ensuring data consistency upon mapping of a hierarchical data format to a relational database management system.According to the invention, a method for ensuring data consistency upon storage of a data item in a database, the data item having an identifier and a locator for linking the data item to a destination, whereby the identifier and the locator are stored in the database in addition to the data item, comprises the steps of: checking (11) whether the current combination of identifier and locator has already been stored in the database, and using (12) the stored combination of the data item if this is the case, in case the current combination of identifier and locator has not yet been stored in the database, checking (13, 15) whether either the identifier or the locator has already been stored in the database, replacing (14, 16) the current combination of identifier and locator with a univocal combination if this is the case, and storing (17) the univocal combination together with the data item, and storing (17) the current combination of identifier and locator together with the data item else.

    摘要: Optical disc players are today connectable to the Internet, and may contain local storage capability, e.g. ADD. Additional post-production content can be downloaded and locally stored. It is difficult to include downloaded additional post-production material in menus for keeping a menu always consistent with the actually available data. Ideally, the menu should reflect the available data even if certain content is deleted or replaced with e.g. Another version. A ‘linked-list’ approach for menu pages generates a dynamic menu structure. The menu consists of basic menu pages, which are retrieved from the disc, and additional pages that are downloaded together with the additional content. Page ranges may be reserved for e.g. audio, video or subtitles. The linked-list is implemented by an implicit link from each page to the next higher or lower page number.

    摘要: A particular implementation accesses a disparity value for a particular location in a picture, the disparity value indicating disparity with respect to a particular resolution. The particular implementation modifies the accessed disparity value based on multiple resolutions to produce a modified disparity value. Another implementation accesses a disparity value for a particular location in a picture, the picture having a particular resolution, and the disparity value indicating disparity with respect to another resolution that is different from the particular resolution and that is based on multiple resolutions. A further implementation modifies the accessed disparity value to produce a modified disparity value indicating disparity with respect to the particular resolution.

    摘要: The invention addresses the objective of optimizing performance of a media data carrier interpreting device. This is achieved by a media data carrier interpreting device which comprises means for transforming a machine- interpretable instruction comprised in a media data carrier into a machine-executable code during media content presentation. Said media data carrier comprises a set of machine-interpretable instructions generated according to a method which comprises the steps of generating a first auxiliary set of instructions corresponding to a set of elements wherein the elements are conform with a template and compiling said first auxiliary instruction set. Then, said compiled first auxiliary instruction set is linked with a compiled second auxiliary instruction set corresponding to said template. This method removes the need for runtime parsing and therefore frees processing capacity for runtime transformation of the machine-interpretable instructions into machine-executable code.
