  • Publication number: 20120017247
    Abstract: The invention provides a content broadcasting system comprising a communications satellite and a satellite control arrangement for controlling the communications satellite to transmit a satellite broadcast signal. The satellite control arrangement is arranged to control the satellite to transmit the satellite broadcast signal to a first geographical area during a first time interval and to transmit the satellite broadcast signal to a second geographical area during a second time interval. The broadcast signal is not transmitted to the first geographical area during at least the second time interval and the broadcast signal is not transmitted to the second geographical area during at least the first time interval. This enables broadcast content to be provided to a large geographical area, while increasing the radio frequency spectrum efficiency of the system and minimising the continuous power consumption of the satellite required for the broadcast.
