UHD Display Window Layout Control for HD Video Upscaling Artifacts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Ultra high definition (UHD) displays often present high definition (HD) video by upsampling, which can lead to image artifacts due to the lack of optimized programming, failing to fully utilize their higher resolution capabilities.
Innovation Solution
A control device with a processor and transceiver that allows users to select and configure window layouts on UHD displays, enabling the presentation of content in various configurations while adhering to presentation rules, and allowing users to resize windows, thereby optimizing the use of UHD display capabilities.

Engineering Contradiction Analysis
1Area of stationary object
If HD video is upscaled to fill the entire UHD display, then the display area is fully utilized, but image artifacts appear and the higher resolution capabilities are not fully exploited
Solution Approach 1:
The display area is divided into multiple picture regions (first picture region and second picture region) that can be independently configured. This segmentation allows different content to be displayed in different regions with different resolutions, enabling the UHD display to show HD content in one region while preserving native UHD content in another region, thus avoiding upscaling artifacts while utilizing the full display area.
2Adaptability or versatility
If multiple picture regions are configured on UHD display, then the higher resolution capabilities are fully utilized, but the device complexity increases
Solution Approach 1:
The system provides self-service through automated picture region configuration based on content type detection. The control device automatically determines whether incoming content is HD or UHD and configures the appropriate picture region layout without requiring manual user intervention. This reduces the perceived complexity for users while maintaining the versatility of multiple picture region configurations.
Solution Approach 2:
The picture region configuration is dynamic and adaptable rather than fixed. The system can automatically adjust the number, size, and position of picture regions based on the detected content resolution and type. This dynamic configuration capability allows the system to optimize display settings in real-time without requiring complex manual setup procedures.

AI summary
A UHD display presents multiple video windows and a control device enables a user to establish the layout of the windows, either by selecting from templates of predetermined layouts or by constructing a custom layout. The UHD display can communicate messages to the control device if a particular layout fails to conform to predetermined rules depending on the types of applications to be presented in the various windows.
