A data receiving device ( 2 a) is arranged to run a media guide application through which a user may access a service provided over broadcast network ( 3 ). Should reception of the service be interrupted, for example, by an incoming telephone call over telecommunications network ( 4 ), the data receiving device ( 2 a) operates in a first resource saving mode where data is received by receiver ( 11 ) but neither processed nor output. The received data may be stored for later output or simply discarded. The service can then be resumed, with minimal delay, by restarting processing and outputting of received data, as it is not necessary to reactivate or resynchronise the receiver ( 11 ). After operating in said first resource saving mode for a predetermined time period, the receiver ( 11 ) may be deactivated in order to further save power. Applications used in receiving, processing and/or outputting the received data, may be closed down following the expiry of one or more further predetermined time periods. |
