Display Device Genre Change Delay Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices face challenges in maintaining image quality when switching between programs, as they often apply image processing settings for the next program too early, leading to degraded image quality during the transition.
Innovation Solution
A display device with a receiver for video data and genre information, an acquirer for image quality information, a genre detector for change detection, and a controller that delays image quality setting changes until a predetermined period after genre information change detection, ensuring appropriate image processing for the current program.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If image processing settings are changed immediately when genre information changes is detected, then the system responds quickly to program switches, but image quality is degraded because the settings apply to the wrong program
Solution Approach 1:
The system performs preliminary detection of genre information changes and prepares for future action. When genre information changes are detected, the system does not immediately apply new settings but instead waits for a predetermined period to confirm the actual program switch before applying the image processing settings, ensuring settings match the correct program
Solution Approach 2:
A time delay mechanism acts as an intermediary between genre information detection and image processing setting application. This intermediary period allows the system to verify whether the program actually switches before committing to new settings, preventing premature application of incorrect settings
2Manufacturing precision
If image processing settings are delayed until program switch is confirmed, then image quality is maintained, but the system responds slower to genre information changes
Solution Approach 1:
The system applies a partial delay (predetermined period) rather than complete waiting. This partial action balances the need for verification with the need for timely response, applying settings after a reasonable wait time that minimizes user-perceived delay while ensuring accuracy

AI summary
A display device includes a receiver that receives at least video data and genre information, an acquirer that acquires image quality information corresponding to the genre information, a genre detector that detects a change in the genre information, and a controller that performs, when a change in the genre information is detected, control such that image quality of the video data is set based on image quality information corresponding to the changed genre information when a predetermined period of time has elapsed after a time point when the genre information is changed.
