CA 2314201

A method for reducing the power consumption of a radio receiver, and in particular a digital audio broadcast receiver, is described, in which the RF tuner of the receiver is powered up during portions of the received signal which contain information relating to the location of data within the signal. The tuner is then also powered up at various other times in response to this information, in order to allow the reception and demodulation only of selected data. In this way, it is possible to power down the tuner during some portions of the signal, thereby reducing power consumption.
