The invention concerns a radio communication terminal, comprising first means for transmitting/receiving RF signals to communicate in a cellular radio communication network, said first means being in standby mode when no communication is set up in the cellular network with another terminal or with the network itself. The invention is characterized in that the terminal comprises second means for receiving at least one carrier dedicated to collective data of multimedia contents, said second means being activated only when the first means are n standby mode. The invention also concerns a method for broadcasting and receiving collective data, as well as a system for broadcasting multimedia contents.

Radio communication terminal broadcasting et reception method and broadcasting system

System and method for use in a hybrid multispot satellite broadcasting system comprising at least one satellite (S; S; S) for multibeam broadcasting of beams in respective frequency bandwidths (F; F; F), the system further comprising a plurality of terrestrial repeater (R; R; R) for receiving, processing and re-transmitting said beams in a frequency bandwidth which is different from that of the bandwidth of the beam received. Each terrestrial repeater (R; R; R) re-uses for terrestrial re-transmission a combination of bandwidths corresponding to different beams broadcast from said satellite to different beams.

System and method for efficient frequency use in a hybrid multi-spot satellite broadcasting system

An optimized method for the transmission of multimedia contents between a multimedia content transmitter and a multimedia content receiver in a mobile radio network transmitting a multimedia content description vector from the transmitter to the receiver, calculating a pertinence score of the content from the description vector and as a function of a user profile associated with a user of the receiver, and recovering, at the explicit request of the receiver, a block or blocks of the content not received by the receiver, with a priority depending on the pertinence score associated with the content to which the missing block(s) belong(s).
