ABSTRACT:
A terminal13for selectively receiving broadcast data in a transport stream7over a first network, the broadcast data including a series of bursts of associated data packets (B1), comprises a controller16and a receiver19. The controller16is configured to extract information identifying a group of data packets from the data packets within a first burst, e.g. Packet Identifier (PID) PID1, PID2, calculate a burst length and burst interval for the series on the basis of the times at which data packets are received by the receiver and to calculate one or more instances of time tsat which one or more subsequent bursts in the series will be received based on the calculated burst length ts3and/or burst interval t1. The receiver19is operated to selectively receiving the transport stream7, e.g. by switching the receiver19between its on and off states, the receiver19being switched on at time isfor a period equal to the burst length in order to receive subsequent data bursts in the series. The terminal13may be further configured to enable mobile telephone communication via a second network.
