摘要： A method is provided in order to determine connection topology of a home network. The main idea of the present invention is to send out a topology determination message on each link of the network, wherein the topology determination message is constituted of two consecutive packets, first one being a broadcast packet with a predetermined payload that identifies it as a topology determination packet, and second one being a unicast packet with the same content and a non-existent destination MAC address. If a node receives both the broadcast and unicast packet from a sending node, the sending node is determined to be on the same physical link with said receiving node and the MAC address of the sending node is added into a local link nodes list of said receiving node, otherwise if said receiving node receives only the broadcast packet from the sending node, the send node is determined not to be on the same physical link with said receiving node.

摘要： The inventive method for reserving at least one node of a communication network like the Ethernet bus in the form of a predetermined fraction of the Ethernet bus bandwidth consists in circulating a token between the network nodes in such a way that they are enabled to successively transfer an Ethernet packet to a bus according to a given sequence which defines a chronological order for the token passage between nodes and in which a predetermined fraction of the bandwidth reserved for a network node corresponds in sequence to a certain number of passage occurrences of the token through the considered node. Said invention can be used for domestic communication networks like the Ethernet bus.

摘要： In a method of managing a request for remote access to a multimedia content, a corresponding datum stream is inserted at the instant or in a delayed manner with the set of the data streams being transmitted on a distribution network as a function of a capacity threshold of this network. Each data stream is of the variable-throughput type, with a data throughput profile corresponding, whose width corresponds to a time of transmission of the stream. The management of the request comprises a verification that the capacity of the network is not exceeded on the width of the profile, as a function of a given instant of insertion, of the throughput of the data stream or streams in progress on the said distribution network, obtained on the basis of the throughput profiles of these streams, and of the throughput profile of the requested stream.

摘要： Methods 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 provides, 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 the first packet containing the first timing reference in response to a positive determination.

摘要： The present invention relates to a method for receiving audiovisual programs sent by a server to at least two reception devices. Initially, a first user requests a document from the server that establishes a unicast stream to download said document. Then, a second user requests to receive the same document, even truncated by a part. The server studies the proposal and possibly, for a lower price, agrees to the download. The server then switches the broadcast of the document from a unicast stream to a multicast stream, the first and second devices receiving said document via the same multicast stream.The invention also relates to a device for receiving audiovisual content and a server for implementing the method.
