Display Apparatus Virtual Channel Parameter Matching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display apparatuses face challenges in optimizing the playback of audio and video data from various application players due to mismatched playing parameters, leading to poor playback effects as they use the same parameters for all players, requiring cumbersome adjustments to match each player's content.
Innovation Solution
The display apparatus employs virtual channels with independent playing parameters for each application player, allowing it to automatically match the appropriate parameters for the content being played, ensuring optimal playback quality by correlating application players with specific virtual channels and their corresponding parameters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the display apparatus uses the same playing parameters for all application players, then the device complexity is reduced and operation is simplified, but the playback quality deteriorates because parameters cannot match the specific content from each player
Solution Approach 1:
The patent segments the unified parameter set into application-specific parameter sets, where each application player has its own dedicated playing parameters stored in the parameter storage module. This segmentation allows parameters to be tailored to each application's content characteristics while maintaining independent management, resolving the contradiction between playback quality and parameter management complexity.
Solution Approach 2:
The patent implements local quality by assigning different playing parameters to different application players based on their specific content requirements. Each application player retrieves parameters locally from the parameter storage module that are optimized for its content type, ensuring high playback quality for each application without requiring complex global parameter management.
2Manufacturing precision
If the display apparatus uses application-specific playing parameters, then the playback quality improves by matching parameters to content, but the device complexity increases due to multiple parameter sets
Solution Approach 1:
The parameter storage module serves multiple functions: it stores playing parameters for multiple different application players simultaneously, manages parameter retrieval for each application, and adapts to various content types. This multi-functionality allows the system to maintain application-specific parameters without proportionally increasing overall system complexity.
Solution Approach 2:
The parameter storage module acts as an intermediary between the multiple application players and the display apparatus processing units. It centralizes parameter management, receiving content information from various applications and providing appropriate parameters to the display and audio processing units, thereby simplifying the overall system architecture despite having multiple parameter sets.
3Manufacturing precision
If manual adjustments are required to match playing parameters for each application player, then the playback quality can be optimized, but the ease of operation deteriorates due to cumbersome adjustments
Solution Approach 1:
The system implements self-service by automatically retrieving and applying the appropriate playing parameters for each application player based on content information. The display apparatus autonomously matches parameters without requiring manual user adjustment, achieving both optimized playback quality and ease of operation through automated parameter selection and application.
Solution Approach 2:
The system uses feedback mechanisms where the content information from each application player is analyzed, and based on this feedback, the appropriate playing parameters are automatically selected and applied. This closed-loop process ensures optimal playback quality is achieved automatically without user intervention, resolving the contradiction between parameter optimization and operational convenience.
