Method and apparatus for selective data reception
First Claim
1. An apparatus, comprising:
- a receiver configured to receive broadcast data in a data stream, wherein the broadcast data includes a series of bursts of associated data packets; and
a controller;
wherein the controller is configured to;
extract information identifying a group of data packets from the data packets within a first burst;
calculate a burst length and burst interval for the series on the basis of the instances of time at which data packets are received by the receiver;
determine a further instance of time at which a subsequent burst corresponding to the extracted information in the series is expected to be received based on at least one of said burst length and burst interval; and
operate the receiver to receive the subsequent burst corresponding to the extracted information by selectively receiving the data stream.

Abstract
A terminal 13 for selectively receiving broadcast data in a transport stream 7 over a first network, the broadcast data including a series of bursts of associated data packets (B1), comprises a controller 16 and a receiver 19. The controller 16 is 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 ts at which one or more subsequent bursts in the series will be received based on the calculated burst length ts3 and/or burst interval t1. The receiver 19 is operated to selectively receiving the transport stream 7, e.g. by switching the receiver 19 between its on and off states, the receiver 19 being switched on at time is for a period equal to the burst length in order to receive subsequent data bursts in the series. The terminal 13 may be further configured to enable mobile telephone communication via a second network.
