Abstract: An interleaver (ER) is dedicated to interleaving of interleaving units representing a selected number of services grouped into periodic frames within a long period time interleaving radio communication network. The said interleaver (ER) comprises processing means (MT1) responsible for decomposing each frame into a chosen number of group(s) of service of constant respective durations, and then for distributing the interleaving units of each group into so-called spreading time intervals of constant respective durations spaced apart within a time interleaving period according to a period equal to the period of the frames.

Abstract: IP encapsulation equipment encapsulates, into bursts, IP packets representing sets of multimedia data delivered by at least one multimedia content server. The bursts are accompanied beforehand by information data at least partly defining the set of data that is integrated into those IP packets and/or the content of which that set of data forms part, with a view to the broadcasting thereof to receiver equipments via a communication network. The information data added to the received IP packets is analyzed to instruct the encapsulation means to encapsulate at least some of those IP packets in selected positions in the bursts as a function of the corresponding information data. In this manner, all the IP packets including, the data of a set, are encapsulated in a single burst.

Abstract: Within a user device to which a radio communication network infrastructure transmits data carried by a sequence of frames broadcast to the user device, each frame comprising a first section comprising data and a second section comprising redundancy information associated with the data of a predetermined number B of previous frames in the sequence, a number of consecutive lost frames is compared to a threshold dependent on the number B of previous frames with which said redundancy information is associated and encoding parameters that generate said redundancy information, and a request to retransmit at least one of the consecutive lost frames is sent to the radio communication network infrastructure if the number of consecutive lost frames exceeds said threshold.

Abstract: A relay for use in telecommunications equipment, said relay comprising: a receiver (R) adapted to receive an information stream consisting of information cells, some of which can be empty, a mixer (M) adapted to detect the empty cells and replace them with waiting cells, and a transmitter (E) adapted to transmit the cells to a receiver, which relay is characterized in that it further comprises a stream analyzer (A) for determining if an information stream is a real-time information stream or a differed-time information stream and for storing differed-time stream cells in a mass memory (MM), and in that said mixer is adapted to choose said waiting cells from among the cells stored in said mass memory.

Abstract: The invention concerns a method of communication between ground stations via satellites traveling around the Earth and forming part of a constellation overflying at least a major portion of the Earth, each ground station communicating during a particular time with a given satellite of the constellation. Two ground stations communicate via respective given satellites with which the stations are respectively communicating. To minimize the control means on board each satellite, the two satellites communicate via a predetermined communications link. A link of the above kind generally comprises one or more predetermined satellites.
