    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: An architecture for a multimedia peer-to-peer home network allows the simple definition of peer groups, or zones, where each peer is capable of automatically identifying whether other peers are members of the same group, or of another group, by using group labels. Each peer may freely cooperate with the other peers of the same group, or with peers of previously specified other groups. e.g. exchange information or share resources. The architecture aims to map an atmosphere of trust existing between users to a technical system. namely their respective home networks. Using this architecture, it is e.g. possible that users who trust each other may give each other access to their own home network, or parts of it.

    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: 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: 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: 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.

    摘要: A logical quality-of-service management method for peer-to-peer networks uses a special group service for QoS management within peer-groups. This group service determines and assigns a budget per time unit for each peer. Such time unit may be in the range of milliseconds or few seconds. It may also determine a group budget for the peer-group. While a peer uses bandwidth, i.e. while it sends or receives data, its budget is decreased. When a peer has exhausted its budget, it has to lower its priority for transferring or receiving data. Each peer is responsible for keeping its own budget. If a peer does not keep the conditions, other peers may have the right to deny the data transfer from that peer. The QoS service function is advertised in peer-group advertisement messages.

Therefore, a method is presented in which a metadata-template is filled with selected essence and MD-links obtained from a list of links to essence and/or a list of current metadata.
