Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Image distribution providers face challenges in identifying which bit rate contributes to decreased experience quality, making it difficult to design and redesign systems to improve user experience.
Innovation Solution
An information processing apparatus that includes an experience quality estimation unit, a contribution degree calculation unit, and a contribution degree output unit. This apparatus estimates experience quality values by replacing index values in viewing history data with alternative values corresponding to different bit rates, calculates the contribution degree of each bit rate to the experience quality, and outputs this information.

Engineering Contradiction Analysis
1Measurement precision
If a complicated experience quality estimation model with multiple index values is used, then the experience quality estimation becomes comprehensive, but it becomes impossible to identify which specific bit rate causes deterioration in experience quality
Solution Approach 1:
The patent segments the overall experience quality estimation into individual bit rate contributions. By calculating the contribution degree of each bit rate separately through controlled replacement of index values, the system divides the complex estimation problem into manageable components that can be individually analyzed and identified.
Solution Approach 2:
The patent introduces an intermediary mechanism - the contribution degree calculation - that mediates between the complex multi-index estimation model and the need for simple bit rate identification. This intermediary layer processes the complex inputs and produces simplified, actionable insights about which bit rates affect experience quality.
2Adaptability or versatility
If various index values and complicated models are used for experience quality estimation, then the estimation covers multiple factors, but the system complexity increases making design and redesign difficult
Solution Approach 1:
The patent extracts the essential information needed for decision-making from the complicated estimation model. By calculating contribution degrees that isolate each bit rate's impact, the system extracts actionable insights without requiring users to understand or manage the underlying model complexity.
Solution Approach 2:
The patent changes the output parameter from a single aggregate experience quality value to multiple contribution degree values, one for each bit rate. This parameter transformation maintains the comprehensive assessment capability while simplifying the interpretation and application of results for system design and redesign.
