Video Correction Lookup Tables for Display Compatibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current video technology is limited by the need for multiple master files for different display types, which becomes impractical with the increasing variety of complex display technologies, as existing standards like REC609 and REC709 struggle to accommodate various display capabilities and distribution complexities.
Innovation Solution
A system and method that uses a translation module to correct video sequences using lookup tables, allowing for universal display on multiple display types by separating correction information from the original video sequence and applying appropriate lookup tables for each display type during playback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple master files are created for different display types, then display compatibility is improved, but distribution complexity and manufacturing cost increase
Solution Approach 1:
The patent segments the correction process into separate lookup tables (LUTs) that can be independently applied to a single master file. Instead of creating multiple master files for different display types, the system divides correction information into discrete, manageable LUTs that can be selectively applied, reducing distribution complexity while maintaining display compatibility across different devices
Solution Approach 2:
The patent creates a universal master file that can be displayed on multiple different display types by incorporating multiple lookup tables within a single file. This universal approach allows one master file to serve multiple functions across different display technologies (CRT, LCD, plasma, etc.) without requiring separate master files for each display type
2Adaptability or versatility
If multiple master files are created for different display types, then display compatibility is improved, but storage requirements and data volume increase
Solution Approach 1:
The patent segments correction information into separate lookup tables that can be stored efficiently within a single master file. By dividing the correction data into discrete LUTs rather than creating multiple complete master files, the system reduces overall data volume while maintaining the ability to display correctly on different display types
Solution Approach 2:
The patent embeds multiple lookup tables within a single master file structure, creating a nested organization where correction information for different display types is contained within one parent file. This nesting approach allows multiple correction profiles to be stored compactly without requiring separate master files, reducing storage requirements
3Adaptability or versatility
If correction information is stored separately from original video sequence, then flexibility and adaptability are improved, but processing complexity increases
Solution Approach 1:
The patent introduces lookup tables as intermediary structures that bridge the original video sequence and the desired corrected output. These LUTs serve as mediators that translate correction information into actionable pixel data, allowing flexible adaptation to different display types while managing processing complexity through pre-computed correction lookup tables

AI summary
A method and system for determining correction information for the universal display of an original video sequence on a plurality of displays includes correcting an original video sequence using a first display, storing correction information related to the correction of the original video sequence using the first display, correcting the original video sequence using a different display, and determining and storing the differences between the correction information related to the correction of the original video sequence using the first display and using a particular, different display. Subsequently and prior to the display of the original video sequence, the original video sequence is corrected using a combination of the stored correction information related to the correction of the original video sequence using the first display and the respective determined differences, if any, related to a particular, different display on which the original video sequence is now to be displayed.
