Abstract: A method of navigation in at least one graphic user interface coming from a device included in a communications network comprising a plurality of devices, comprises the following steps implemented in a controller connected to a display device: the detection of a first navigation command signal coming from a remote-control unit and associated with a function; the verification of the display, on the display device, of at least one graphic user interface of the controller in which navigation functions are applicable; in the event of positive verification: the application by the controller of the function associated with the first navigation command signal; in the event of negative verification: the determining of the source device for which a connection with the display device is set up; and the transfer to the source device of at least one piece of information enabling the source device to apply the associated function to the first navigation command signal.

Abstract: A method for the management of the recording of an audio/video stream within a communications network comprises a step for setting up a first recording connection between a source device and a recording device connected to said communications network. The step for setting up the first recording connection is followed by a step for setting up a second viewing connection between the recording device and a display device also connected to the network, so that a user can observe an audio/video image corresponding to the audio/video stream, on said display device, while the stream is being recorded by the recording device.

Abstract: A multimedia interface device for the transfer of information in a communications network comprises: at least two connection means to which, respectively, at least two sending devices can get connected by means respectively of two communications links compliant respectively with two protocols; means of connection to a single remote switching device by means of a single cable, the switching device comprising at least switching means between at least two ports; means to mix the information sent out by sending devices into only one stream of information in the form of segments being able to contain part of the information; and means to transfer the stream of information in the form of segments on at least one pair of cable to the switching device to which it is connected according to a third protocol.

Abstract: A method for setting up a connection of data streams between a source terminal and a destination terminal connected to a communications network comprises the following steps: a partial connection of streams is set up between the source terminal and the destination terminal, through an intermediary device that is connected to the network, said connection being partial in that the intermediary device does not let through the stream to the destination terminal so long as a first predetermined event has not occurred; on the occurrence of said first predetermined event, the intermediary device lets through the stream to the destination terminal, so that a full connection of streams is set up between the source terminal and the destination terminal. This first method can be applied especially in a second method for the selection of a stream from amongst a plurality of data streams and for setting up a connection for a selected stream.

Abstract: A system for the transmission of audiovisual signals between at least one source node and at least one destination node comprises: at least one central switch to which at least one source node is connected and at least two home audiovisual networks, each comprising a plurality of nodes each capable of playing the role of a destination node to which said audiovisual signals are transmitted from said at least one source node. Each home audiovisual network is connected to said at least one central switch by means of said at least one of its nodes. Said at least one central switch comprises interconnection management means. These means themselves comprise means for the selective authorisation of a first type of transmission of audiovisual signals through said at least one central switch from said at least one source node to at least one of the destination nodes of one of the home audiovisual networks.

Abstract: Method for setting up an isochronous data stream connection between at least one entry terminal or talker and at least one addressee terminal or listener connected by at least one bridge of a digital bus networ.

Abstract: In a method for the transmission of audiovisual signals between at least one source node and at least one destination node of a home audiovisual network, said source node or nodes insert a piece of information, into said audiovisual signals, to control the copying and/or broadcasting of said audiovisual signals by said destination node or nodes.
