    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.

    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: In the field of data storage on limited rewritability storage media, handling frequently changing databases may lead to unequal wear of storage segments. The invention discloses a method for modifying a database file, which ensures maximally distributed segment wear in that any writing of data records uses a next available segment after the last written segment; and a reading method. A data carrier according to the method, containing a database file with records having version numbers is also disclosed.

    摘要: The present invention relates to a method for mapping a hierarchical data format to a relational database management system. It is an object of the invention to provide a method for mapping a hierarchical data format comprising descriptors to a relational database management system capable of handling diverse types of hierarchical descriptors in a fast manner for inserting descriptors, reading parts of descriptors, reading whole descriptors and performing fast text queries. According to the invention, the descriptors are separated into portions of a common format, which are stored in a relation in the relational database.

    摘要: Compression parameter sets are stored in files separate from the main AV or transmitted separately and prior to any subsequent transmission of AV data. The scope of parameter set identifiers is limited to not more than a Program Chain. Either existing files are extended by including the compression parameter sets directly, or separate files containing the compression parameter sets are created. In order to support easy authoring of compound content, it is proposed to amend each compression parameter set or groups of such parameter sets with scope period information, which can be based on time stamps, on file names, or on sector numbers on the disc. It is additionally proposed to employ an indirect referencing mechanism, where parameter set identifiers are referring to secondary tables, and where the entries of secondary tables are defined to be themselves identifiers referring in turn to entries of a common parameter set table provided once.

    摘要: A method and an apparatus for recovering a component of a distortion field of an image of a set of multi-view images are described. Also described are a method and an apparatus for determining a disparity field of an image of a set of multi-view images, which makes use of such method.In a first step pixel correspondences between the image and another image of the set of multi-view images are determined. A disparity field is then determined from at least a subset of the determined pixel correspondences. The disparity field is smoothed and the component of the distortion field is estimated from the smoothed disparity field. When determining a second disparity field the estimated component of the distortion field is taken into account when determining pixel correspondences between the image and another image of the set of multi-view images.

    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.
