UHD Display Segmentation for HD Video and Ancillary Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Ultra high definition (UHD) displays often present high definition (HD) video by upsampling, leading to image artifacts due to the lack of optimized use of their higher resolution capabilities.
Innovation Solution
An UHD display system that presents HD video using at least 1440 pixel lines, leaving unused portions for ancillary information, which can be received from TV signals or the Internet, allowing users to choose between full-screen upscaling or partial display with ancillary content.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If HD video is upscaled to fill the entire UHD display, then the display area is maximized, but image artifacts appear and visual quality deteriorates
Solution Approach 1:
The display area is segmented into multiple regions: a primary video display area showing HD video at native resolution without upscaling, and secondary ancillary display areas showing additional content. This segmentation allows the video portion to maintain high quality while utilizing the full display area through multiple content streams.
Solution Approach 2:
The solution transitions from a single-dimension approach (upscaling video to fill the screen) to a multi-dimensional approach by displaying video and ancillary information simultaneously in different spatial regions of the display, effectively utilizing the extra resolution capacity in UHD displays.
2Manufacturing precision
If HD video is presented at native resolution without upscaling, then image quality is maintained, but unused display portions are wasted
Solution Approach 1:
The UHD display serves multiple functions simultaneously: displaying the primary video content at high quality and presenting ancillary information in unused portions. This multi-functionality ensures full utilization of the display's resolution capabilities while maintaining video quality.
Solution Approach 2:
The display continuously utilizes all available resolution capacity by simultaneously presenting video content and ancillary information without idle pixels, ensuring that the high-resolution capabilities of the UHD display are constantly exploited for useful purposes.
3Area of stationary object
If ancillary information is displayed in unused portions, then display space is fully utilized, but device complexity increases
Solution Approach 1:
The system uses an intermediary processing layer that receives both video and ancillary information streams, manages their respective rendering requirements, and coordinates their display in appropriate regions. This intermediary architecture simplifies the overall complexity by providing a dedicated management layer.
Solution Approach 2:
The system performs preliminary processing of ancillary information and video streams separately before combining them for display. By preparing content in advance and organizing it into designated display regions beforehand, the real-time processing complexity is reduced.

AI summary
A UHD display presents HD video in the native resolution of HD, leaving some portions of the UHD display unused for presenting the HD video. Ancillary information received, for example, in real time with the HD video or in parallel with the HD video over the Internet is presented in the unused portions of the UHD display along with the HD video.
