Media Detection Resets Screensaver Timeout
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users experience interruptions while watching videos on computer devices or mobile phones due to screensaver activation, requiring frequent user input to reset timeouts or disabling power-saving settings, which can lead to battery depletion after use.
Innovation Solution
Implementing a media data monitor that detects audio or video data via an interface connection, such as HDMI, to reset the screensaver timeout duration, maintaining the connection and preventing interruptions during media playback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the screensaver timeout is set to a short duration for power savings, then battery life is extended, but video playback is interrupted frequently
Solution Approach 1:
The patent introduces an intermediary mechanism (audio/video detection system) that mediates between the screensaver power-saving function and video playback continuity. The system detects media playback through audio/video signals and automatically adjusts screensaver timeout settings, allowing both power savings and uninterrupted playback without requiring manual user intervention.
2Reliability
If the user manually disables the screensaver or sets a long timeout, then video playback continuity is maintained, but power is not conserved after use
Solution Approach 1:
The system performs self-service by automatically detecting when video playback occurs and adjusting screensaver settings accordingly. When playback ends, the system automatically restores power-saving settings without requiring user intervention. This eliminates the need for manual configuration while ensuring both playback continuity during use and power conservation after use.
Solution Approach 2:
The patent implements a feedback mechanism where the system continuously monitors for audio/video signals and adjusts screensaver timeout settings based on detected playback status. This closed-loop feedback ensures that power-saving settings are dynamically optimized according to actual usage conditions, preventing both interruptions during playback and unnecessary power consumption afterward.
3Reliability
If the user frequently resets the screensaver timeout during video playback, then playback continuity is maintained, but user convenience deteriorates
Solution Approach 1:
The system eliminates the need for manual user intervention by automatically detecting video playback through audio/video signal monitoring and autonomously adjusting screensaver timeout settings. This self-service approach maintains playback continuity while completely removing the burden of frequent manual resets from the user.
Data Source
AI summary
In embodiments of system timeout reset based on media detection, an electronic device includes an interface connection that couples the electronic device to a peripheral. A power manager application is implemented to timeout the interface connection if user interaction with the electronic device is not detected for a timeout duration. A media data monitor is implemented to detect audio data in an audio channel of the interface connection, and initiate a reset of the timeout duration responsive to the audio data being detected. Video can continue to be rendered by the peripheral if the audio data is detected to initiate the reset of the timeout duration.
