It is desired to link photo data and video data taken by a digital camcorder. Therefore, there is provided a device and method for linking multimedia data, wherein linking information is formed on the basis of first and/or second multimedia data. The linking information is stored on a recording medium together with the first multimedia data. The second multimedia data may be stored together with respective linking information to the first multimedia data on a second recording medium. Thus, a camera-man while recording is able to set up logo or index pictures for a video film.

The handling of large amounts of data on storing media shall be simplified. Therefore, a method for maintaining a storage media by generating, editing or reading log data related to the content and usage of a data item stored or to be stored on a storage medium is provided. Data items are deleted or recommendations for deletion are provided on the basis of the log data from the storage medium. Thus, the user is relieved from the unpleasant and time-consuming task of deleting data items from recording media.

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.

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.

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.

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.

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.

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.
