Display Screen Resource Sharing Across Split-Screen Video Sources
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current display devices are limited in their ability to share resources across different video source devices, preventing cross-platform resource sharing.
Innovation Solution
A display device equipped with video connection terminals, a display screen, memory, and a processing circuit that allows resource sharing between itself and video source devices via a user input device, utilizing divided frames and temporary storage regions with associated lists to manage resource sharing operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If resource sharing is limited to the display device only, then the display device can maintain simple operation and structure, but the resource sharing range is limited and cannot share resources with connected video source devices
Solution Approach 1:
The user input device is designed to serve multiple functions: it can receive user inputs for both the display device and multiple video source devices, and issue commands that work across all connected devices. This universal input mechanism enables cross-platform resource sharing without requiring separate input devices for each device, thus expanding resource sharing range while controlling system complexity.
2Adaptability or versatility
If multiple video source devices are connected to enable cross-platform resource sharing, then resource sharing versatility improves, but the complexity of managing resource sharing operations increases
Solution Approach 1:
The display device acts as an intermediary between the user input device and multiple video source devices. It receives user inputs, determines the active video source device, and routes commands to the appropriate device. This intermediary role simplifies the user experience by providing a single point of control while managing the complexity of multiple connected devices in the background.
Solution Approach 2:
The system pre-establishes the association between the user input device and multiple video source devices before resource sharing operations begin. The display device maintains readiness to receive and process commands for any connected device, so when a user issues a resource sharing command, the system can immediately act without requiring additional setup or configuration steps.
3Adaptability or versatility
If resources are shared between display device and video source devices, then resource sharing capability expands, but the time required to manage and complete sharing operations increases
Solution Approach 1:
The system performs preliminary actions by pre-establishing communication channels and data structures between the display device and video source devices before resource sharing operations are initiated. Temporary storage regions are pre-configured to hold resource data, and the system maintains ready-state connections, enabling rapid resource sharing when commands are issued without requiring time-consuming setup procedures.

AI summary
A display device includes at least one video connection terminal, a display screen, a memory, and a processing circuit. The video connection terminal is arranged to receive at least one video source from at least one device. The display screen is arranged to display at least one divided frame corresponding to the device on an original frame corresponding to the display device. The memory is arranged to store a program code. The processing circuit is arranged to read and execute the program code from the memory, in order to share resources in the divided frame between the display device and the device according to a user input.
