摘要： The method can be used to provide a solution to the allocation of multicast addresses within a local area network by stream servers, particularly audio/video. This solution does not involve configuration or particular servers. The invention relies on the use of identifiers of the transmitted stream to construct the multicast address. Also, this method enables the transmission client to know the duly constructed multicast address to subscribe to a stream.

摘要： A method for transmitting first packets encapsulated in second packets in a transmission system in which part of the first packets contain a first timing reference for synchronization of a receiver clock and at least part of said second packets contain a second timing reference for reducing transmission jitter of the second packets at the receiver is described. This method is characterized by the steps, at the transmitter, collecting first packets, determining whether a collected first packet contains a first timing reference and triggering transmission of a second packet encapsulating collected first packets including said first packet containing the first timing reference in response to a positive determination.

摘要： The invention concerns a solution for detecting conditions of dearth and overflow of a client input buffer to a real time content distribution. Said detection is performed upstream of clients through a dynamic estimation of the fill factor of the input buffers of said clients. Thus, it is possible to predict the occurrence of dearth or overflow situations and to take actions such as inserting stored video sequences or storing queueing packets.

摘要： The invention consists in a procedure for generating an address value within a terminal linked to a communication network. Initially, the terminal receives a pair of address values sent by a configured terminal. Then, the terminal determines a characteristic value of the network which is contained in the first and the second address values. The terminal then calculates a third address value containing the characteristic value of the network. Finally, the terminal assigns the third address value to the terminal if this value is not already assigned to another terminal. According to a refinement, the terminal sends a request to a terminal having this third request; if there is no response, this third address value does not belong to another terminal, so it can be assigned to the terminal to be configured. The invention also relates to the terminal designed to implement the procedure. The invention also relates to a terminal which receives a message comprising a first and a second address values. It is assigned the second address value if it turns out that the latter is not assigned to any other terminal of the network.

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.
