Display Control System for Automatic Video Input Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current display control systems face challenges in efficiently detecting and switching video input types on display apparatuses connected to servers, leading to a high workload for administrators due to the need for manual examination and potential failure in switching to unsupported video signals, especially when the types and number of video input terminals are unknown.
Innovation Solution
A display control system that includes a management apparatus and a display apparatus connected via a network, where the management apparatus automatically requests connection for various video signal types, determines connectability, and notifies the administrator of available input types, preventing switching to unsupported signals and reducing preparation time and workload.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual examination and storage of video input terminal information is performed by server administrator, then information on video input terminals can be stored in the server, but the workload and time required for preparation is considerably large
Solution Approach 1:
The display apparatus automatically transmits its own video input terminal information to the server through data communication, eliminating the need for manual examination by the server administrator. The system performs self-registration where the display apparatus provides its own configuration information automatically.
Solution Approach 2:
The manual mechanical process of administrator examination and information entry is replaced with an automated data communication system. The server automatically receives and stores video input terminal information through network communication, substituting human effort with automated digital processes.
2Adaptability or versatility
If standard video signals are used for input switching control, then compatibility with most display apparatus is improved, but switching may fail for apparatus that only accept special video signals
Solution Approach 1:
The server transmits control data to the display apparatus and receives feedback on whether the input switching was successful. Based on this feedback, the server can learn which video signal types are supported by each display apparatus and adjust future switching operations accordingly, improving both compatibility and reliability over time.
Solution Approach 2:
The system dynamically changes the video signal parameters (input types) based on the specific display apparatus being controlled. Instead of using a fixed standard signal type, the server adapts the signal parameters to match the capabilities of the target display apparatus, ensuring successful switching while maintaining broad compatibility.
3Loss of information
If sequential input switching operations are performed for all standard video signals, then connectable input types can be detected, but the workload and time required is large due to unnecessary switching attempts
Solution Approach 1:
The display apparatus pre-transmits information about its connectable input types to the server before any switching operations are performed. This preliminary provision of capability information allows the server to plan and execute switching operations efficiently without needing to perform sequential trial-and-error switching to detect supported types.

AI summary
A management apparatus includes a connection request transmitter transmitting, to a display apparatus, a connection request requesting video signal acquisition by the display apparatus for each input type of video signal, a connectability determiner determining whether a connection to the display apparatus is available using a connection response acquired from the display apparatus for each input type of connection request, and a connectable input notifier informing an input type determined to be connectable. The display apparatus includes a connection switching processor executing a connection operation for acquiring a video signal corresponding to a requested input type, a connection switching confirmer determining whether acquisition of a video signal corresponding to the input type is successful by the connection operation, and a connection response transmitter transmitting a connection response including a connection result indicating whether acquisition of a video signal is successful that is determined to the management apparatus.
