Metadata Control for Stable Graphic Menus in HDR Video
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
High dynamic range (HDR) content reproduction technologies cause fluctuations in brightness and color of graphic menus during video content playback due to dynamic metadata changes, leading to inconsistent visual experiences.
Innovation Solution
An electronic apparatus and display apparatus system that provides static metadata during graphic content activation periods, replacing dynamic metadata with calculated values or static metadata to maintain consistent brightness and color, ensuring the intended visual characteristics of graphic content are preserved.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If dynamic metadata is used for HDR content reproduction, then image quality and brightness optimization for each scene are improved, but brightness and color of graphic menus fluctuate during playback
Solution Approach 1:
The patent applies local quality by differentiating metadata processing between video content regions and graphic menu regions. The system identifies graphic menu areas and applies static metadata specifically to these regions while maintaining dynamic metadata for video content, allowing each region to have optimized and appropriate metadata characteristics.
Solution Approach 2:
The patent segments the display content into video content portions and graphic menu portions, then applies different metadata strategies to each segment. This segmentation allows the system to maintain scene-optimized brightness for video while ensuring stable brightness for graphic menus.
2Manufacturing precision
If dynamic metadata changes are applied during scene transitions, then visual quality of video content is improved, but visual consistency of graphic content deteriorates
Solution Approach 1:
The system applies different quality characteristics to different content types: dynamic metadata processing for video content to maintain high image quality precision, and static metadata processing for graphic menus to maintain visual consistency and stability.
3Adaptability or versatility
If metadata is continuously updated for each content period, then adaptability to different scenes is improved, but stability of graphic content appearance worsens
Solution Approach 1:
The patent implements local quality by applying scene-adaptive dynamic metadata to video content while applying stable static metadata to graphic menus, allowing the system to be adaptable to different scenes for video while maintaining stable appearance for graphic content.
Data Source
AI summary
An example electronic apparatus includes a communication interface including communication interface circuitry; and a processor configured to provide video content and dynamic metadata corresponding to video content of each predetermined content period to an external display apparatus through the communication interface, wherein the processor is configured to provide metadata based on graphic content to the display apparatus during at least one content period in which the graphic content is activated.
