Multimedia Image Definition Adjustment via Metadata-Driven Presets
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of UHD displays experience discomfort due to hyper-realism, and there is a need for automatic adjustment of image settings based on the multimedia program characteristics, as existing technologies only allow manual adjustments through limited remote control options.
Innovation Solution
A method for automatically adapting image settings by defining and applying predefined settings based on metadata from the Electronic Program Guide or online services, using Boolean expressions to select optimal parameters like brightness, contrast, and sharpness, allowing for seamless switching between predefined presets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If UHD format is used to display images, then image sharpness and detail are improved, but viewer comfort deteriorates due to hyper-realism
Solution Approach 1:
The patent applies dynamics by making the image processing mode adjustable and switchable between different presets (UHD, HD, SD) based on program characteristics and user preferences. The system dynamically selects the appropriate processing mode rather than using a fixed UHD setting, allowing adaptation to different viewing conditions and program types to maintain comfort while preserving sharpness when needed.
Solution Approach 2:
The patent changes parameters by offering multiple predefined settings (UHD, HD, SD) that modify key image parameters such as resolution, sharpness, and detail level. Users can select different parameter sets depending on the program type and personal comfort preferences, transforming the static parameter approach into a flexible, multi-parameter solution.
2Adaptability or versatility
If manual adjustment of image settings is provided through configuration menus, then customization capability is improved, but ease of operation deteriorates due to complex menu navigation
Solution Approach 1:
The patent applies preliminary action by pre-configuring multiple predefined settings (UHD, HD, SD) with optimized parameter combinations for different program types and viewing conditions. Users don't need to manually adjust each parameter individually; instead, they can quickly select from pre-prepared settings that are already optimized for specific scenarios, significantly reducing operational complexity.
Solution Approach 2:
The patent achieves universality by creating a multi-functional preset system where each predefined setting encompasses multiple image parameters (resolution, sharpness, detail, color settings). A single preset selection simultaneously adjusts multiple parameters, making the system universally applicable to different program types and viewer preferences without requiring separate adjustments for each parameter.
3Manufacturing precision
If scaling processing is used to convert images to native definition, then image definition is improved, but processing time and complexity increase
Solution Approach 1:
The patent applies preliminary action by pre-determining the appropriate output definition (UHD, HD, SD) based on program characteristics and user preferences before processing begins. This allows the system to select the most appropriate scaling algorithm and processing parameters in advance, avoiding the need for complex real-time analysis and adjustment during image processing.
Solution Approach 2:
The patent changes parameters by offering multiple output definition options (UHD, HD, SD) that correspond to different processing complexity levels. Users can select lower definition modes when maximum sharpness is not required, thereby reducing processing complexity while maintaining adequate image quality for the given application.
4Adaptability or versatility
If multiple predefined settings are provided for different program types, then adaptability is improved, but device complexity increases
Solution Approach 1:

Users don't need to manually adjust each parameter individually; instead, they can quickly select from pre-prepared settings that are already optimized for specific scenarios, significantly reducing operational complexity.

AI summary
The invention concerns a method for setting the level of definition of at least one image of a multimedia programme displayed on a screen of a terminal provided with at least one unit for characterising the multimedia programme and at least one unit for selecting predefined settings. This method comprises the following steps: - the characterisation unit automatically acquires metadata attached to said multimedia programme and submits said data to the unit for selecting predefined settings, - the unit for selecting predefined settings automatically selects the settings according to pre-recorded rules defined depending on the values of said metadata.
