摘要： A method is intended for disseminating content data in a peer-to-peer mode between peers connected to at least one communication network. This method comprises the steps of: i) making peers exchange neighboring information between them to build a bipartite peer overlay comprising a first group, comprising peers having a complete content to be disseminated, and a second group, comprising peers having not this content or only a part of it and having links therebetween, ii) disseminating the data defining the content (and preferably encoded with erasure correcting codes) from peers of the first group to first peers of the second group according to the bipartite peer overlay, iii) disseminating the data received by the first peers to other peers of the second group according to the bipartite peer overlay, and iv) updating the bipartite peer overlay when a peer of the second group has fully completed the content.

摘要： In a method and an apparatus for navigating through subtitles of an Audio Video data stream an address information of one or more played back data units is stored together with the subtitle information of said played back data units during play back of said data units. One or more of said stored subtitle information can be displayed. Following the selection of one of said displayed subtitle information the stored address information of the data unit corresponding to the selected subtitle information is retrieved and the corresponding data unit is accessed using said retrieved address information. Playing back the accessed data unit conveniently allows to watch and listen to a scene including subtitles again, e.g. by a few clicks on the remote control.

摘要： The present invention relates to a module and a process for inter-user communication across a bidirectional network. The module comprises a unit for triggering recording, in a storage space of a server, of information received by the server from users via the bidirectional network, and a unit for controlling a broadcasting of data stored in the storage space to the users, via a broadcasting network. It also comprises a unit for monitoring connection of the users to the server via the bidirectional network. Moreover, the unit for triggering recording and/or the unit for controlling broadcasting is designed to operate as a function of the users connected to the server which are identified by the monitoring unit. Advantageously, the bidirectional network is temporary and the broadcasting network is a permanent unidirectional network. Applications to P2P technology, in particular for television.
