    摘要: In modern digital video recorders not only the video/audio data stream itself is stored in data packets on the medium but also additional information about the stream. Part of this additional information is navigation information for random access to segments within the recorded material. A playlist is used that includes a sequence of substructure information data carrying start and end time data and addressing mode information for the segments. The substructure information data provide information describing each segment within one recording and where the segment data can be found on the storage medium. Because the playlist level does not include addressing mode information for the segments, segments having any addressing mode can be replayed using a single playlist.

    摘要: Networks may be implemented using peer-to-peer technology. A plurality of peers may form a peer-group, having a unique group label. To relieve the user from administrative tasks, some configuration routines for such networks may be automated. A peer-group may select one of its peers as negotiation peer, having the task to communicate with other peers, e.g. negotiation peers from other peer-groups. When merging or splitting peer-groups, the group label is usually modified. But it may be advantageous to keep the group label. If a new peer-group in a peer-to-peer network is created by merging or splitting of peer-groups, a method for selecting a group label for the new peer-group comprises determining a negotiation peer, exchanging information between the negotiation peers in the case of merging, comparing features of the two peer-groups and assigning the label of one of the peer-groups to the new peer-group.

    摘要: Current peer-to-peer systems are well defined for messaging and collaboration of peers running the same proprietary software and protocols, e.g. Kazaa or EDonkey. The generic framework JXTA for P2P computing provides various peer-group mechanisms and may address different applications, but provides no convenient method for exchanging messages between different peer-groups. The invention discloses a bridging concept and a delegate concept to establish communication between a first and a second peer-group, including the steps of a first peer being either a member of the first peer-group or a secondary peer relating to a primary peer, wherein the primary peer is a member of the first peer-group, sending a message to the second peer-group; a second peer being a member of the second peer-group receiving said message, detecting credentials of first peer and first peer-group, and detecting whether a connection is allowed; and if so, granting the first peer membership with the second peer-group.

    摘要: A distributed storage system able to support real-time recording of streaming data shall be provided. Therefore, on the basis of Material Exchange Format (MXF) formatted files a data stream is packed into at least a first MXF formatted file and a second formatted MXF file. First connection data are inserted into the first MXF formatted file, wherein this first connection data points to the second MXF formatted file. Furthermore, second connection data are inserted into the second MXF formatted file, wherein the second connection data points to the first MXF formatted file. These connection data inserted as metadata into the MXF formatted files enable both seamless real-time stream recording and stream-able data playback.

    摘要: The handling of metadata being provided in different formats shall be simplified. Therefore, it is suggested to provide metadata in a first metadata structure having a first format and providing a second metadata structure having a first format and providing a second metadata structure having a second format, wherein link data are deposited in the second metadata structure. The link data point to metadata in the first metadata structure. Thus, it is possible to trealize synchronous and automatic editing of metadata and its mirror metadata.

    摘要: An architecture for a multimedia peer-to-peer home network allows the automated definition of peer groups, or zones, by using group labels, where each peer is capable of automatically identifying whether other peers are members of the same group, or of another group, and where each peer may freely cooperate with other peers of the same group, e.g. exchange information or share resources like storage capacity. Using this architecture, it is e.g. possible that a user who is accessing a node within a peer group has also access to any other node of the peer group, without being requested for authentication. Another characteristic is that other peer groups can be defined which have access rights to network resources and services. Advantageously, the invention simplifies network creation and operation by not requiring the user to have special networking knowledge.

    摘要: The invention relates to the updating of a local copy of metadata. First change history data of metadata are read from an optical storage medium. Second change history data of the metadata are read from a local storage of an optical storage medium playback and/or recording device. If the first and second change history data are different a change attribute is read a from the optical storage medium and an update operation of the metadata stored in the local storage or an update operation in the optical storage medium is determined depending on the change attribute.

    摘要: When recording packetized real-time streaming data, e.g. multimedia data, it is in general not possible to know in advance the size of the data stream, and thus the required storage area. Therefore the storage device may be full before the data stream is completely stored. The disclosed method for storing and retrieving the remaining part of the data stream on another storage device uses metadata tags (10,11) and data buffers (IB1,IB2) to split a data stream seamlessly into chunks while recording it, and distribute the chunks in real-time to different connected storage devices (D1,D2), so that the chunks can be seamlessly concatenated again in real-time for replaying the stream. The metadata tags (10,11) contain identifiers for the successive storage node (N2) and/or the preceding storage node (N1) and for the last stored application packet.
