Audio Playback Pause Mechanism for Power Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In user equipment, the normal mode of audio data processing consumes high power, and there is a need to reduce power consumption, especially in mute playing scenarios.
Innovation Solution
An audio data processing method that involves receiving decoded audio signal frames, determining the average power of these frames, and triggering a deactive playing state if the average power is below a preset threshold, pausing the audio playing program to conserve power, with additional checks based on ratios of frames and continuous conditions to improve accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If normal mode processing is used for audio playback, then audio processing capability is maintained, but power consumption increases
Solution Approach 1:
The patent implements dynamic switching between normal mode and deactive mode based on real-time detection of audio signal characteristics. The system transitions from a static processing mode to a dynamic one that adapts to content requirements, enabling low-power operation during mute scenarios while maintaining full capability when needed.
Solution Approach 2:
The system changes the processing parameter state by introducing a deactive mode where the audio processing program pauses execution. This parameter change (from active to paused state) reduces power consumption while the detection mechanism ensures the change is appropriate for the current audio content.
2Loss of energy
If audio playback is paused to reduce power consumption, then power consumption decreases, but audio playback continuity is affected
Solution Approach 1:
The patent employs feedback through continuous monitoring of audio signal power levels. The system detects when audio content is mute or low-power by analyzing signal characteristics, and only pauses playback when the detected signal confirms mute conditions, ensuring playback continuity is maintained when audio content requires it.
Solution Approach 2:
The system performs preliminary detection of audio signal characteristics before pausing playback. By analyzing audio frame power levels and detecting mute conditions in advance, the system ensures that playback is only paused when appropriate, preventing unintended interruptions.
3Loss of energy
If deactive mode is used for mute detection, then power consumption is reduced, but detection accuracy may decrease
Solution Approach 1:
The patent implements periodic detection of audio signal power levels at defined intervals (e.g., every audio frame). This periodic sampling maintains detection accuracy by continuously monitoring signal characteristics while allowing the system to operate in a low-power state between detection cycles.
Solution Approach 2:
The system performs partial processing by pausing the audio processing program rather than completely shutting it down. This partial action (pausing vs. stopping) maintains the ability to quickly resume processing and ensures accurate detection by keeping the detection infrastructure active while reducing overall power consumption.

AI summary
An audio data processing method comprises receiving at least one audio signal frame from an audio playing program, obtaining a first average power of the at least on audio signal frame, determining whether the first average power of the at least one audio signal frame is less than a first threshold and whether the audio playing program is in a background running mode, and in response to determining that the first average power of the at least one audio signal frame is less than the first threshold and the audio playing program is in the background running mode, triggering the audio playing program to pause playing.
