The invention relates to a method for allocating at least one identifier known as routing identifier to at least one bridge () of a network (), the said bridge comprising at least two interconnection equipment () a first () of which is connected to at least one first part () of the said network, characterized in that each one of the interconnection equipment of the said bridge being in a 'state' determined by reference to the allocation of an identifier to this interconnection equipment, the said method includes the following steps: determination () of at least one 'state' which corresponds to the &#x201c;state&#x201d; of the said at least one second interconnection equipment of the said bridge, deciding () as to the allocation of an identifier to the at least one first interconnection equipment of the said bridge as a function of the said at least one determined &#x201c;state&#x201d;.

Method and device for allocating at least one routing identifier to at least one bridge in a network

Processing signals from a remote control device within a home audiovisual network comprising a plurality of nodes for interconnecting a plurality of terminals, wherein, within the network, at least two types of remote-control signals are used, including first type remote-control signals specific to the nodes and sent by at least one first remote control device associated with the nodes, and second type remote-control signals specific to the terminals and sent by at least one second remote control device associated with at least one of said terminals. Each node of the network, called a local node, when receiving a first remote-control signal, performs analysis of the type of the received first remote-control signal, if the type of the received first remote-control signal is determined to be one of the first type remote-control signals, processing the signal and performing at least one function in response to the received first remote-control signal, if the type of the received first remote-control signal is determined to be one of the second type remote-control signals, transparently sending said received second type remote-control signal to a target node if the target node, to which a target terminal is connected, has been determined beforehand, said target terminal being connected with said target node, through at least one predetermined link between the target node and the target terminal, and if no target node has been determined beforehand, ignoring said received second type remote-control signal.

The invention relates to a method for allocating at least one identifier known as routing identifier to at least one bridge of a network, the bridge comprising at least two interconnection equipment a first of which is connected to at least one first part of the said network, characterized in that each one of the interconnection equipment of the said bridge being in a 'state' determined by reference to the allocation of an identifier to this interconnection equipment, the method includes the steps of determination of at least one 'state' which corresponds to the &#x201c;state&#x201d; of the at least one second interconnection equipment of the bridge, and deciding as to the allocation of an identifier to the at least one first interconnection equipment of the bridge as a function of the at least one determined &#x201c;state&#x201d;.

Method and device for assigning at least one routing identifier to at least one bridge in a network

A method of communicating digital information of different data formats via a plurality of communication channels shared between several communication means includes a reception operation, a reformat operation, and a transmission operation. In the reception operation, digital information having a first format and transmitted via a first communication channel from communication means that uses the first format is received. In the reformat operation, the received digital information having the first format is reformatted to digital information having a second format different from the first format, if resources to use a second channel for transmission of digital information having the second format are available. In the transmission operation, the digital information having the second format is transmitted via the second channel and is received by communication means that uses the second format.

Data processing apparatus with communication feature, and communication method in a data processing apparatus

A device for communication, between at least two asynchronous computer buses, having at least one intermediate storage unit adapted to be accessed in read and/or write mode at least two different frequencies. Each computer bus includes an adapter for interfacing between the computer bus and a memory. Each adapter has an adapter memory and two bidirectional ports, one of the bidirectional ports being connected to the computer bus and the other bidirectional port being connected to the storage unit. Each intermediate storage unit can be accessed in write and/or read mode by each of the computer buses and the interface adapter which is associated with the computer bus.
