Abstract: A device is disclosed for compressing data contained in input frames to be compressed constituted of stream frames defining portions of TRAU and signaling frames that have to be transmitted within a communication network and each of which is constituted of at least a header containing control data representative at least of the type of stream frame and where applicable payload data, certain types containing critical and/or non-critical data. The device analyzes each TRAU or signaling frame header contained in successively received input frames in order to determine its type and generates periodically compressed frames to be transmitted that are divided into first and second sections of variable size. The first section contains critical data compressed synchronously and the second section contains non-critical data compressed asynchronously.

Abstract: The invention relates to a multiplexing device comprising a data compressor. The compressed data block leaving said compressor occupies a particular bandwidth.

Abstract: A method of broadcasting multimedia information items, a receiver of multimedia information items broadcast by that method, and a user interface for consulting the information items. The invention relates to a method of broadcasting multimedia information items in a network comprising a transmitter and at least one receiver of information, the method including determining a class to which each information item belongs, broadcasting ahead of time a descriptor relating to each information item, at each receiver, qualifying the potential interest of each information item on the basis of the descriptors received and as a function of a user profile defined in the receiver, broadcasting the information items associated with the descriptors previously broadcast, and, in each receiver, storing locally each information item as a function of the qualification based on the descriptors. The invention also relates to a receiver and a user interface for consulting broadcast information items.

Abstract: A point-to-multipoint or multipoint-to-multipoint communications network includes remote traffic stations connected to a management center (CG) by radio links sharing resources. The management center (CG) includes a management module for determining a primary distribution of the resources, including assignment margins, between the radio links that it manages and previously set up between the traffic stations, as a function of first information data representing rates of occupancy per traffic type of the resources previously assigned to the radio links. Each traffic station can then determine a secondary distribution between its traffic types of the resources assigned to its radio link as a result of the primary distribution, taking account of its own rates of occupancy per traffic type.

Abstract: In a secure method of deciding on a communication channel in a data decompression device, the compressor detects channels that vary from one frame to another, which are referred to as “active” channels. It transmits active and passive channels in a data block which also contains a state code locating the active data in the starting frame in order to be able to reconstitute it in the decompressor. A reference pattern is transmitted incorporating the passive channels and a majority vote statistical analysis is applied to the states of the passive channels to decide on the state (0 or 1) of each bit constituting the pattern repeated by each passive channel. One particular application of the method is to a satellite telecommunication system.

Abstract: The invention concerns a device for data broadcasting in an access network consisting of several interconnected nodes for transporting fluxes of information elements between content providers and reception terminals. The invention is characterised in that said device is implanted at least at one node of the network, and it comprises a circuit managing the profile of the node (8) configured by an operator of the network or of the node (4) on the basis of objective or even subjective criteria and a mechanism filtering (6) broadcast information elements which controls a switch (5) so as to filter said information elements.

Abstract: A point-to-multipoint or multipoint-to-multipoint communications network comprises remote traffic stations connected to a management center (CG) by radio links sharing resources. The management center (CG) comprises management means (13) for determining a primary distribution of the resources, including assignment margins, between the radio links that it manages and previously set up between the traffic stations, as a function of first information data representing rates of occupancy per traffic type of the resources previously assigned to the radio links. Each traffic station can then determine a secondary distribution between its traffic types of the resources assigned to its radio link as a result of the primary distribution, taking account of its own rates of occupancy per traffic type.

The invention also relates to a data decompressor, a data block containing a data group compressed in accordance with the invention, and a bandwidth resource management method. Particular application in a satellite telecommunication system.
