UHD Video Processing via Display Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current technologies fail to optimize the viewing experience of ultra-high definition (UHD) content across various display devices due to limitations in color and brightness expression, which are restricted by the physical characteristics of the devices, especially when content is provided through external devices.
Innovation Solution
A video processing method and apparatus that transmit display-related information from the display device to the source device, allowing for the reception and processing of UHD video according to the display device's capabilities, including color gamut conversion and brightness adjustment, to ensure optimal viewing conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If UHD content is provided through external devices, then content delivery flexibility is improved, but color and brightness expression is restricted by display device characteristics
Solution Approach 1:
The display device transmits its characteristic information (color gamut, brightness range) to the external source device in advance, enabling the source device to pre-process the UHD content to match the display device's capabilities before transmission, thus resolving the color and brightness expression restrictions
Solution Approach 2:
The source device adjusts video parameters (color space, brightness levels) based on the display device's characteristic information to optimize the content for the specific display device, thereby improving color and brightness expression while maintaining delivery flexibility
2Adaptability or versatility
If display device characteristics are delivered restrictively, then device compatibility is improved, but optimal viewing experience is lost
Solution Approach 1:
The display device provides feedback about its characteristics to the source device, which then adjusts the content parameters accordingly, creating a closed-loop system that ensures both compatibility and optimal viewing experience
3Manufacturing precision
If content is converted based on accurate display device analysis, then viewing quality is improved, but processing complexity increases
Solution Approach 1:
The display device extracts and transmits only the essential characteristic information (color gamut, brightness range) needed for content conversion, rather than performing complex analysis itself, thus improving viewing quality while minimizing processing complexity
