Power Management Techniques for Waking-Up Processors in Media Playback Systems

Abstract:

According to at least one aspect, power management techniques are disclosed that may reduce the power consumption of devices, such as those devices in media playback systems, without introducing a noticeable lag between a user issuing a command and the device processing the command. In some embodiments, the device may put to sleep (including turn off) electronic components that are only used for specific commands. In these embodiments, the devices may identify periods where the specific commands are likely to be invoked and, in response to identifying such a period, wake-up the electronic components. As a result, the power consumption of the device may be substantially reduced because various electronic components may be put to sleep instead of remaining idle in an awake state.
