Abstract
Techniques for controlling one or more audio amplifiers in or associated with a device coupled on a local area network are disclosed. The device receives at least one selected source from other devices also coupled on the network According to one aspect of the techniques, an automatic shutdown control module is provided in the device to power down the audio amplifiers when there is no audio data flow coming to the device or power up the audio amplifiers when there is audio data flow coming to the device. In one embodiment, the procedure to power down or power up the amplifiers is in accordance with a hysteresis, wherein the hysteresis, being lagging of an effect behind its cause, protects the amplifiers and makes the powering-down or powering-up procedure unnoticeable to a user.

29. A playback device comprising:
-
one or more processors; a network interface; and tangible, non-transitory, computer-readable memory comprising instructions that, when executed by the one or more processors, cause the playback device to; operate in a first power mode in which the playback device consumes a first amount of power; while operating in the first power mode, receive one or more packets addressed to the playback device via the network interface, and determine that the one or more received packets comprises a specified type of data packet; and after determining that the one or more received packets comprises the specified type of data packet, transition from operating in the first power mode to operating in a second power mode in which the playback device consumes a second amount of power, wherein the first amount of power is less than the second amount of power. - View Dependent Claims (30, 31, 32, 33, 34, 35, 36, 37, 38, 39)
