Abstract
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.
