Automatic Pairing via Image Signal for Display Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional image display systems require explicit network address designation and additional communication means for automatic linking of image output devices and image display devices, leading to non-automatic pairing and increased complexity.
Innovation Solution
The system automatically links image output devices and image display devices by transmitting a pairing start image signal, allowing them to exchange and register network addresses, such as IP addresses, upon connection, using a local area network.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If network addresses are explicitly designated for linking image output device and image display device, then communication reliability is improved, but device complexity and ease of operation deteriorate due to manual configuration requirements
Solution Approach 1:
The system enables automatic pairing where the image output device and image display device self-register their network addresses with each other through image signal transmission, eliminating the need for manual user configuration while maintaining reliable communication
Solution Approach 2:
The system performs preliminary network address registration during the pairing phase before actual image transmission begins, so that when image transmission starts, the communication path is already established and verified
2Adaptability or versatility
If additional communication means such as infrared communication are used for pairing, then pairing functionality is improved, but device complexity increases due to multiple communication interfaces
Solution Approach 1:
The image signal cable serves multiple functions: it simultaneously transmits both pairing information (network addresses) and image signals, eliminating the need for separate pairing protocols or additional communication interfaces like infrared
Solution Approach 2:
The system merges the pairing function and image transmission function into a single communication channel, allowing the same cable and protocol to handle both device discovery/registration and content delivery
3Measurement precision
If pairing is triggered by user instruction via remote controller, then control precision is improved, but automation level deteriorates requiring manual intervention
Solution Approach 1:
The system automatically detects when the image cable is connected and initiates the pairing process without requiring user instructions, with the devices self-registering their addresses through the transmitted image signals

AI summary
An image display system according to the present disclosure includes a plurality of image output devices and a plurality of image display devices that are connected to one another via a network. When a predetermined image output device that is one of the plurality of image output devices and a predetermined image display device that is one of the plurality of image display devices are connected, the predetermined image output device transmits a pairing start image signal to the predetermined image display device. The predetermined image display device receives the pairing start image signal transmitted from the predetermined image output device.
