Abstract: A broadcast decoder operable in a low power mode and a high power mode, comprising circuitry configured to: receive physical layer data in the low power mode; detect a parameter in the physical layer data, and in the event of a positive detection of the parameter, the circuitry is further configured to: determine delay data; switch the broadcast decoder to operate in the high power mode at a specified time after detection of the parameter, the time being defined by the delay data; and trigger an alert.

Abstract: A receiving device for receiving data is described. The described receiver comprises a first receiver configured to receive data in a first frequency band; a second receiver configured to receive second data in a second frequency band, the second frequency band being a subset of the first frequency band; and a data selector configured to select the frequency of operation of the second receiver from within the second frequency band in accordance with information representing the physical geographical location of the receiving device.
