Abstract: The present invention relates to a method of synchronization between communication networks exchanging information by frame of informations, each communication network having clock and the number of clock pulses is monitored by a counter the synchronization is made by reading information representing the counted clock pulses of the clock of the first network at the appearance of a reference event, inserting at least said information or calculated information on the basis of said information into the frame of information as the synchronization information, transferring said frame of information from the first to the second network, reading information representing the number of counted clock pulse of the clock of the second network at the appearance of reference event, reading synchronization information inserted in received frame of information from the first network, calculating a difference between information and synchronizing the second network.

Abstract: The present invention relates to a method of synchronisation between communication networks exchanging information by frame of informations, each communication network having clock and the number of clock pulses is monitored by a counter. The synchronisation is made by reading information representing the counted clock pulses of the clock of the first network at the appearance of a reference event, inserting at least said information or calculated information on the basis of said information into the frame of information as the synchronisation information, transferring said frame of information from the first to the second network, reading information representing the number of counted clock pulse of the clock of the second network at the appearance of reference event, reading synchronisation information inserted in received frame of information from the first network, calculating a difference between information and synchronising the second network.

Abstract: The present invention concerns a method and an apparatus of generating a reference event in a receiving node receiving frames of information, when a frame of information is received, the method and the apparatus sample the frame of information in order to form sampled data, process sampled data in order to detect among said sampled data a specific data, monitor the number of processed sampled data until the detection of a specific data and generate a reference event according to the result of processing and monitoring.

Abstract: Disclosed is a method for communicating audiovisual signals over a communication network interconnecting a plurality of devices, wherein the method comprising the steps of: selecting an audiovisual signal at a first device; transmitting an indication message from the first device to a group of devices over the communication network, said indication message containing a set of parameters associated to the selected audiovisual signal; selecting a second device among the group of devices, said selection being performed at said second device; and establishing a connection for retrieving at the selected second device the audiovisual signal using at least one of the set of parameters.

Abstract: An information packet transmission device for a communication system has a transmission part and a reception part, at least one of the transmission or reception parts having a turbocoder, and an external interleaver upstream of the turbocoder. The turbocoder preferentially has an interleaver, and a deinterleaver of the “x to xe” type. The external interleavers are of the row column or column row type.

Abstract: A method for the processing of control signals within an audiovisual network comprises at least one element (20) liable to send a digital command signal to at least one peripheral (181, 182), called an analog peripheral, designed to receive analog commands. The processing method implements, in a conversion device (241, 242), a conversion (92) of the digital command signal into at least one of the analog commands, said conversion being selectively configured as a function of said peripheral.

Abstract: A method of transmitting binary data by a sender to a receiver over a transmission channel includes a formatting function integrated with a function of external coding of the binary data. The method applies in particular to the case where the sender uses a turbocoder with an interleaver of the “x to xe” type, and where the receiver uses a turbodecoder with an interleaver of the “x to xe” type.

Abstract: In a communication network, a method of reading, by a controlling node, the configuration memory of a terminal connected to the network, the terminal being able to include at least one functional unit having a temporary character and having been configured according to a configuration method according to the invention.

Abstract: The invention concerns a method and device for declaring at least one functionality of a node in a network comprising at least two nodes, each node connected to the network sending over the network, following the occurrence of a predetermined event on the network, a set E of data representing its functionalities and if, amongst the sets E of data sent over the network, none includes at least one data item representing a predetermined functionality, the method generates the predetermined event on the network and sends the set E of data comprising at least one data item representing the predetermined functionality on the network
