    摘要: The resistance against recording defects of a write-once optical disk is enhanced allowing realtime recording and playback of data streams with a single speed disk drive. A data stream is recorded in data blocks on the optical disk. An error correction block for one or more data blocks is generated and written on the same optical disk during recording. A spare data area is kept blank on the storage medium and used for storing a defect data block reconstructed by using the error correction block.

    摘要: For the creation and self-organization of peer-groups the JXTA protocol may be used, which includes messages such as peer or peer-group advertisements and services such as the discovery service. Conventional peer-groups of this type are static and need restart after any modification, e.g. a new service. A method for dynamically managing hardware and/or software elements, e.g. services, utilized and/or offered by such peer-groups comprises detecting a change within a peer-group, creating a new peer-group identifier, publishing within the peer-group a first peer-group advertisement message that includes the current and the new peer-group identifier and pointers to current services including the detected modification, accepting the new peer-group identifier by the other peer-group members, and publishing a second peer-group advertisement message in the superordinate peer-group, wherein both advertisement messages may be identical. Thus, peer-groups may operate continuously while peers modify, add or delete services.

    摘要: According to the invention sub-picture data are organized in sub-picture units, the sub-picture units comprising pixel data in a pixel data area as well as display control data and/or address information data, wherein a sub-picture unit of a second sub-picture stream is inserted into the pixel data area of a sub-picture unit of a first sub-picture stream. This permits several sub-picture streams for systems, which are defined to allow only a single sub-picture stream. Especially for DVD-VR conflicts with the already existing DVD-VR specification are avoided. Therefore, enhanced DVD-VR devices using the invention are able to record and playback additional sub-picture streams and conventional DVD-VR devices are able to record and playback the same signal without any compatibility problems, although restricted to only a single sub-picture stream.

    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: The invention relates to a method of editing a data stream, the data stream having a first unique identifier of an identifier space and having assigned metadata, the metadata comprising meta information and a metadata link, the metadata link comprising the first unique identifier and at least one data packet identifier. When performing an editing operation on the data stream, a second unique identifier of the identifier space is assigned to the data stream and the first unique identifier for a resolver task is stored, using a decision metric for updating the meta link.

    摘要: A method enables and controls automatic propagation of metadata items to a recording media or to devices for reading from or writing to recording media. The metadata items are provided with a propagation property, which defines to which recording media or to which devices the metadata items shall propagate, and on which recording media or in which devices the metadata items shall be stored. At least when a recording medium is inserted into or removed from a device, or when the device is powered up or down, the metadata items are automatically propagated and stored in accordance with the propagation property.

    摘要: TVs and other consumer electronics devices like VCRs and DVD players use on-screen display of messages. For display together with MPEG encoded video signals the picture content of an OSD text or graphic is stored in a non-volatile memory in a specific format: the OSD text or graphic content is divided into macroblock units and the OSD macroblock data are stored in MPEG encoded form in the memory. The OSD macroblocks to be displayed are then handled as a slice.
