Media device power management techniques

摘要

Techniques and architecture are disclosed for managing power use during operation of an electronic device capable of processing and/or playback of audio and/or video (AV) content. In some instances, the disclosed techniques/architecture can be used, for example: (1) to stop decoding and/or rendering of AV content upon detecting that a user wishes to stop or is otherwise unable to consume (e.g., hear/listen to or otherwise utilize) such AV content; and/or (2) to continue/re-enable decoding and/or rendering of AV content upon detecting that a user wishes or is otherwise able to continue/resume consumption thereof. In some cases, use of the disclosed techniques/architecture may reduce central processing unit (CPU) cycles, audio digital signal processing (DSP), rendering hardware usage, etc., and/or otherwise make more efficient use of battery charge, and thus may realize an improvement in battery life, for example, for a mobile/battery-operated device capable of AV processing and/or playback.

主权项

1. A system, comprising:
a sensor configured to detect a stimulus relevant to an AV consumption indicator and to output a first signal including data about the stimulus; an analysis module configured to determine if a user of a media player is actually consuming AV content based on the first signal, and in response to signaling of multiple AV consumption indicators, to impose an order on those AV consumption indicators, the order determining at least one of whether one of the AV consumption indicators is to be analyzed in preference over another of the AV consumption indicators and whether one of the AV consumption indicators is of greater significance than another of the AV consumption indicators; and a control module configured to output a control signal to the media player, the control signal for stopping or starting playback of the AV content based on output from the analysis module.
