Playback Adjustment Graph for Digital Media Volume Consistency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users experience abrupt changes in volume levels when transitioning between digital media items, leading to an inconsistent viewing experience due to differing inherent signal levels, causing frustration and the need for manual volume adjustments.
Innovation Solution
A computer-implemented method that analyzes user volume adjustments across multiple media items to form a graph and determine a spanning tree, allowing for automatic playback adjustments to equalize the effective volume level, ensuring a consistent listening or viewing experience by applying calculated adjustment amounts during transitions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If users play back multiple digital media items with different inherent signal levels consecutively, then the user can access diverse content, but the effective volume level changes drastically causing inconsistent viewing experience
Solution Approach 1:
The system performs preliminary analysis of media item signal levels before playback and pre-calculates the adjustment amounts needed. When a user transitions between media items, the system automatically applies the pre-computed volume adjustments, eliminating the need for manual intervention and maintaining consistent effective volume levels across diverse content.
2Ease of operation
If the system automatically adjusts volume levels to maintain consistency, then the viewing experience is enhanced, but the system complexity increases due to graph formation and spanning tree calculations
Solution Approach 1:
The patent introduces an intermediary processing layer that includes a graph formation module and a spanning tree calculation module. This intermediary structure mediates between the diverse media items and the playback system, automatically computing adjustment amounts through graph-theoretic methods. While this adds computational complexity, it enables seamless automatic volume adjustment that enhances user experience without requiring manual intervention.
3Device complexity
If manual volume adjustment is required for each media item transition, then the system remains simple, but user frustration increases and productivity decreases
Solution Approach 1:
The system implements self-service by automatically detecting media item transitions, analyzing signal level differences, and adjusting volume levels without user intervention. The patent creates a self-regulating playback system that monitors its own state and makes necessary adjustments autonomously, thereby eliminating user frustration and improving viewing efficiency while maintaining reasonable system complexity through algorithmic automation.

AI summary
An adjustment module analyzes user adjustments in a playback attribute (e.g., volume) of a media item (e.g., a video) that occur when the user transitions from one media item to another. By analyzing these adjustments, the adjustment module determines an adjustment amount to apply to the playback attribute of a media item to cause the media item to appear equivalent to users with respect to the playback attribute when compared with the media item that was previously played.
