Display Region Segmentation for Multi-Device Screen Sharing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices waste network traffic and computational resources by transmitting and decoding images at native resolution without considering the actual display regions, leading to inefficient screen sharing among multiple electronic devices.
Innovation Solution
The display device splits its screen into regions and transmits display information to each electronic device, allowing them to scale and transmit images accordingly, reducing unnecessary network traffic and computational load.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If images are transmitted at native resolution without considering display regions, then image quality is maintained, but network traffic and computational resources are wasted
Solution Approach 1:
The display device screen is divided into multiple display regions, and each region's resolution requirements are calculated separately. Source devices transmit images scaled to match each specific region's resolution rather than using a single native resolution for the entire screen, reducing unnecessary network traffic while maintaining appropriate image quality for each region.
Solution Approach 2:
Different regions of the display screen are assigned different resolution characteristics based on their actual usage. Images are scaled and transmitted with resolution parameters tailored to each specific display region's requirements, ensuring optimal quality for each area while minimizing overall data transmission.
2Loss of energy
If images are transmitted at native resolution, then image quality is preserved, but computational load increases
Solution Approach 1:
The display device calculates and transmits resolution information for each display region to source devices in advance. Source devices then pre-scale images to the appropriate resolution before transmission, reducing the computational burden on the display device for real-time scaling while maintaining accurate image quality for each region.
3Productivity
If screen sharing is implemented without region division, then implementation is simpler, but efficiency is reduced
Solution Approach 1:
The display screen is segmented into multiple display regions, each with its own resolution characteristics. This segmentation enables efficient screen sharing by allowing source devices to transmit appropriately scaled images for each region, improving overall sharing efficiency while the complexity is managed through automated region detection and resolution calculation.
