Multi-Source Display Control With Priority-Based Area Mapping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices with multiple input sources lack flexibility in processing video images, failing to meet the screen display requirements of certain scenarios.
Innovation Solution
A display control method that receives video streams from multiple sources, determines priority parameters for both display areas and video streams, and generates image data for display based on these priorities, allowing for highlighted and efficient arrangement of video content.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple video streams are displayed using simple processing, then the display device can handle multiple input sources, but the flexibility and adaptability of multi-input display is poor
Solution Approach 1:
The display screen is divided into multiple display areas, each capable of independently displaying different video streams. This segmentation allows flexible arrangement of multiple video sources across different regions of the screen, improving adaptability while maintaining manageable processing complexity through modular area-based control
Solution Approach 2:
The system dynamically adjusts the arrangement and mapping of video streams to display areas based on priority parameters. Video streams can be flexibly assigned to different display areas according to their importance, allowing the display configuration to adapt dynamically to different usage scenarios without requiring complex manual reconfiguration
2Loss of information
If video streams are arranged without priority parameters, then the processing is simple, but the visibility and utilization of important video content is reduced
Solution Approach 1:
Different display areas are assigned different priority levels, allowing important video content to be placed in high-priority areas with better visibility. This local differentiation of quality ensures that critical information receives appropriate visual emphasis while maintaining simple overall processing through standardized priority-based mapping rules
3Loss of information
If display areas are not marked with priority indicators, then the display is clean without additional visual elements, but the user cannot quickly identify the importance of different video streams
Solution Approach 1:
Different priority levels of display areas are marked with different colors, providing immediate visual identification of video stream importance. This color-coding system allows users to quickly distinguish between high and low priority content without adding complex interface elements, as the priority information is conveyed through simple visual differentiation

AI summary
Provided in the present disclosure is a display control method. The method includes: receiving video streams sent by a plurality of video sources, and acquiring a second priority parameter corresponding to each video stream; according to a first priority parameter which is pre-configured for each display area of a display apparatus, and the second priority parameter for each video stream, obtaining a video stream corresponding to each display area; and according to the video stream corresponding to each display area, generating image data, and sending the image data to the display apparatus for display. Further provided in the present disclosure are a display control apparatus, a display device, and a computer-readable medium.
