A method for transmitting/receiving multimedia contents via a radiocommunication network includes a first step of a first server transmitting an identifier specific to a multimedia content over a dedicated point-to-point transmission channel to all terminals registered with the first server as interested in the content, a second step of the first server transmitting to a second server adapted to provide a broadcast content transmission service a request to broadcast a message including the content in its entirety and its identifier, and a third step of the second server broadcasting the message over a broadcast channel.

Method and system for transmitting/receiving multimedia contents via a radiocommunication network

This invention concerns a terrestrial repeater (RF) dedicated to a hybrid communication network comprising a satellite for transmitting to terminals (and at least to the repeater) signals (SPI) in the form of a first modulated carrier with data to be transmitted, encoded by suing initial sequences of at least two pseudo-random codes, and spectrally spread with spreading codes each associated with a sequence. The repeater comprises: i) first processing means (MRP, MTB) for dispreading and demodulating the received signals so as to retrieve the encoded data which they represent for decoding them, and ii) second processing means (MTPi, APi) for re-encoding the retrieved data with one first part of the codes of the corresponding sequence to constitute first encoded data, and with at least a second part of the codes of the corresponding sequence, at least complementary to the first part, to constitute at least second encoded data, and to generate to the terminals, first signals (SP&#x2033;), in the form of the first modulated carrier with the first encoded data and spectrally spread, at lest second signals (SP) in the form of at least and second modulated carrier with the second encoded data and spectrally spread.
