Display-to-Display Image Relay for Indirect External Device Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices lack the ability to easily and efficiently receive image data from external devices connected to another display device without direct physical connection, limiting user convenience and flexibility in content sharing.
Innovation Solution
A first display device can communicate with a second display device to control and receive image data from external devices connected to the second device, using short-range wireless communication and encoding/decoding processes to facilitate seamless content sharing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a display device directly connects to external devices, then image data can be received, but the device cannot access external devices connected to another display device
Solution Approach 1:
The patent uses the second display device as an intermediary to enable the first display device to access external devices. The first display device sends a first signal to the second display device, which then relays the request to the external device and returns the image data. This mediator approach allows indirect access without requiring direct physical connections between all devices.
Solution Approach 2:
The patent introduces a new dimension of indirect access through network communication. Instead of requiring direct physical connections (one-dimensional), the system enables multi-hop connections through intermediate display devices, creating a hierarchical access structure that expands the reachable device space.
2Adaptability or versatility
If multiple connection methods are supported, then device compatibility is improved, but the operation complexity increases
Solution Approach 1:
The patent implements universal communication protocols that allow the display devices to interact through standardized signal types. The first display device can send control signals to the second display device, which can then communicate with various external devices (set-top boxes, Blu-ray players, etc.) using compatible protocols, enabling one device to access multiple types of external devices through a unified interface.
3Ease of operation
If indirect access through another display device is enabled, then user convenience is improved, but communication protocols become more complex
Solution Approach 1:
The patent segments the communication process into distinct phases: a first signal transmission phase from the first display device to the second display device, and a second signal transmission phase from the second display device to the external device. This segmentation allows each communication hop to use optimized, simpler protocols while the overall system achieves complex indirect access functionality.
