    摘要: A distributed storage system able to support real-time recording of streaming data shall be provided. Therefore, on the basis of MXF files a data stream is packed into at least a first MXF file (1) and a second MXF file (2). First connection data 1-N) are inserted into the first MXF file (1), wherein this first connection data (1-N) points to the second MXF file (2) Furthermore, second connection data (2-L) are inserted into the second MXF file (2), wherein the second connection data (2-L) points to the first MXF file (1). These connection data inserted as meta-data into the MXF files enable both seamless real-time stream recording and stream-able data playback.

    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: Networks, particularly home networks, may be implemented using peer-to-peer technology. To relieve the user from administrative tasks, some configuration routines for such networks may be automated. Therefore a peer-group selects one of its peers as negotiation peer, having the task to communicate with single other peers or negotiation peers from other peer-groups. When adding or removing single peers, or merging or splitting peer-groups, the group label is usually modified. But it may be advantageous to keep the group label, especially if that label is known to other peer-groups. If a new peer-group in a peer-to-peer network is created by merging or splitting other 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 based on the comparison assigning the label of one of the peer-groups to the new peer-group.

    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.
