Display Image Quality Matching for Multi-Device Content Playback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multi-device experience (MDE) services face challenges in providing consistent image quality across multiple devices due to differing features and capabilities, leading to inconsistent viewing experiences.
Innovation Solution
An electronic apparatus and method that dynamically adjusts image quality settings based on obtained image quality information from a predetermined device or the device most recently playing back content, using a processor to identify and apply settings based on shared image quality information from external devices or an external server managing MDE information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If image quality settings are fixed for each device, then device complexity is reduced, but image quality consistency across multiple devices deteriorates
Solution Approach 1:
The patent implements a universal image quality information sharing mechanism where a main device's image quality settings are made available to multiple secondary devices through a server. This allows the same image quality parameters (color temperature, gamma, brightness, etc.) to be universally applied across different device types and manufacturers, achieving consistency without each device needing independent complex adjustment mechanisms.
Solution Approach 2:
The system establishes a feedback loop where secondary devices obtain image quality information from the main device via server communication, apply these settings to their displays, and maintain synchronization with the main device's image quality characteristics. This feedback mechanism ensures that image quality settings are dynamically adjusted based on the main device's configuration rather than being statically fixed.
2Reliability
If image quality settings are dynamically adjusted for each device, then image quality consistency is improved, but device complexity increases
Solution Approach 1:
The patent introduces a server as an intermediary that mediates between the main device and secondary devices. The server receives image quality information from the main device, manages this information centrally, and distributes it to secondary devices. This intermediary approach simplifies the complexity by centralizing the adjustment logic on the server rather than requiring complex peer-to-peer negotiation or local processing on each secondary device.
Solution Approach 2:
The system copies the main device's image quality information (color temperature, gamma, brightness, contrast ratio, etc.) and applies it to secondary devices. Instead of requiring complex real-time adaptation algorithms on each device, the patent simply replicates the main device's image quality parameters across the network, achieving consistency through copying rather than complex dynamic adjustment.
3Adaptability or versatility
If image quality information is shared among all devices, then viewing experience is enhanced, but information management complexity increases
Solution Approach 1:
The server acts as an intermediary that manages image quality information centrally, receiving data from the main device and distributing it to secondary devices. This intermediary structure simplifies information management by providing a single point of control rather than requiring each device to independently manage and synchronize information with multiple other devices, thus reducing overall system complexity while maintaining adaptability.
4Adaptability or versatility
If device-specific image quality settings are used, then device independence is maintained, but multi-device experience quality deteriorates
Solution Approach 1:
The patent creates a universal image quality framework where settings from one device (main device) can be universally applied across multiple different device types (secondary devices). Different devices with varying display capabilities can all use the same image quality parameters, achieving multi-device experience consistency without requiring complex device-specific adaptation logic on each secondary device.
