Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display devices require cumbersome user intervention to enable picture-in-picture (PiP) mode, especially when multiple video source devices are connected via wireless projection, and they fail to display video contents from wireless projection sources in PiP mode.
Innovation Solution
A display control method and apparatus that automatically detect new connections, whether wired or wireless, to enable screen-splitting or PiP mode without user input, by processing video signals from multiple source devices and generating composite images for simultaneous display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional display devices require user intervention to enable PiP mode through OSD menu, then the device can properly render PiP mode with correct video source assignment, but the operation becomes cumbersome and complex
Solution Approach 1:
The display device automatically detects multiple video source connections and enables PiP mode without user intervention. The system self-configures by identifying connected video sources and automatically assigning them to main and sub screens, eliminating the need for manual OSD menu navigation while maintaining correct video source assignment.
Solution Approach 2:
The system performs preliminary detection of video source connections before PiP mode activation. By monitoring connection status in advance and pre-configuring the display settings based on detected sources, the device prepares everything needed for PiP mode operation ahead of time, so no user configuration is required when PiP is activated.
2Adaptability or versatility
If conventional display devices support wireless projection, then wireless connectivity is achieved, but they cannot display video contents from wireless projection sources in PiP mode
Solution Approach 1:
The display device is enhanced to universally handle multiple types of video sources including both wired and wireless projection sources within the same PiP mode framework. The system maintains reliable video content display from diverse sources by treating them all through a unified detection and processing mechanism, enabling cross-platform compatibility while preserving display reliability.
Solution Approach 2:
The system introduces an intermediary detection and processing layer that mediates between different video source types (wired and wireless) and the PiP mode rendering function. This intermediary layer standardizes the handling of various source formats and connection methods, ensuring reliable integration of wireless projection sources into PiP mode operation.
3Ease of operation
If the display device automatically detects new connections and enables screen-splitting mode, then user intervention is reduced and user experience is enhanced, but the system must handle complex connection detection and automatic configuration
Solution Approach 1:
The display device performs self-service by automatically detecting new video source connections and enabling screen-splitting mode without user input. The system monitors connection status, identifies the nature of connected devices, and autonomously configures PiP mode parameters, thereby minimizing user intervention while managing the complexity internally through automated algorithms.
Solution Approach 2:
The system implements feedback mechanisms to continuously monitor connection status and adjust display settings accordingly. When a new video source is detected, the system receives feedback about the connection type and source characteristics, then automatically adjusts PiP mode configuration based on this feedback, enabling intelligent adaptation without user involvement.

AI summary
A display control method includes: receiving a first video signal provided by a first video source device to display one or more first images in the first video signal on a display device; when the display device is displaying the one or more first images, establishing a connection with a second video source device and receiving a second video signal provided by the second video source device through the connection; generating one or more composite images based on the one or more first images in the first video signal and one or more second images in the second video signal without receiving a user control input; and displaying the one or more composite images on the display device.
