A method of monitoring a broadcast signal ( 28 ) comprises receiving a broadcast signal ( 28 ), the broadcast signal including a timebase ( 23 ), monitoring the broadcast signal ( 28 ) for an identification signal ( 24 ), and pausing the timebase ( 23 ) if the identification signal ( 24 ) is not present. The method further comprises restarting the timebase ( 23 ), once the identification signal ( 24 ) is present. |
