Media Stream Selective Decode Based on Window Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional media platforms continue to decode and display media streams regardless of user attention, leading to unnecessary resource utilization and power consumption, even when the user is not actively engaging with the content.
Innovation Solution
An apparatus and method that determine the visibility state of an application window associated with a media stream, selectively decoding video content based on whether the window is visible or blocked, using sensors and metrics to prevent unnecessary decode operations when the content is not being viewed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the media platform continues to decode and display media streams regardless of user attention, then the playback performance is maintained and content is always ready for display, but unnecessary resource utilization and power consumption occur
Solution Approach 1:
The system dynamically adjusts the decoding operation based on window visibility state. When the application window is visible, full decoding proceeds to maintain playback performance. When the window is blocked or minimized, decoding is paused or reduced, reducing power consumption while maintaining the ability to resume playback quickly when needed.
Solution Approach 2:
The system changes the operational parameters of the decoder based on visibility conditions. The decoder transitions between different states: full operation when visible, paused or reduced operation when blocked. This parameter change allows the system to balance between maintaining playback readiness and conserving energy resources.
2Speed
If the media platform decodes all content of a media stream irrespective of user attention, then the content is always ready for immediate display, but unnecessary utilization of processors and other power intensive resources occurs
Solution Approach 1:
Instead of performing complete decoding operations when not needed, the system performs partial actions - maintaining minimal processing to keep content buffers populated when the window is visible, and pausing or significantly reducing decoding when the window is blocked. This partial action approach maintains sufficient content readiness while avoiding excessive processor utilization.
Solution Approach 2:
The system periodically checks the visibility state of the application window and adjusts decoding operations accordingly. This periodic monitoring and adjustment allows the system to maintain content readiness during visible periods while conserving processor resources during blocked periods, creating a rhythm of active and inactive decoding phases.
3Loss of time
If the media platform maintains continuous decoding operations, then playback can resume immediately when the user returns to the content, but resource waste occurs when the user is not actively engaging with the content
Solution Approach 1:
The system performs preliminary actions by maintaining content buffers and keeping the decoding pipeline partially active when the window is visible but the user may not be actively watching. This preliminary preparation ensures that when the user returns to the content, playback can resume quickly without significant delay, while avoiding the need for continuous full-speed decoding that would waste energy during periods of inactivity.

AI summary
Systems and methods may determine a visibility state of an application window associated with a media stream, and selectively decode a media stream based on a visibility state. One or more decode operations with respect to media content, such as video content, may be prevented if a visibility state indicates that at least a portion of an application window includes a blocked state. One or more decode operations with respect to media content, such as video content, may be permitted if a visibility state indicates that at least a portion of an application window includes a visible state. The systems and methods result in benefits to resource utilization, such as processor utilization, power consumption, and so on.
