Abstract

A system and method are disclosed for decreasing the amount of power consumed by a wireless signal receiver in a wireless device. Received data is communicated from the receiver to a play-out buffer in communication with a media play-out device. The level of data in the play-out buffer increases when received data is written to the buffer, and the level of data decreases when data is read from the buffer. If the level of data is above a first watermark level, the receiver is transitioned to a sleep mode while data is read from the buffer. When the level of data in the buffer falls below a second watermark level, the receiver is transitioned back to an active mode to receive data. The device communicates status messages (whether the receiver is asleep or active) to the transmitting device so that the transmitting device stops transmitting data when the receiver is in sleep mode, and transmits data when the receiver is in the active mode.
