Display Peripheral Signal Switching with Data Communication Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display apparatuses simultaneously switch peripheral device connections with video signal inputs, which can lead to data protection issues, persistent meeting applications, and potential failures during camera and microphone usage.
Innovation Solution
A display apparatus with a video signal switcher, a discriminator, and a peripheral device signal switcher that suspends peripheral device signal switching when the connection port is in data communication, ensuring that the data communication destination remains consistent with the video signal input source.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If peripheral device connection port is simultaneously switched with video signal input, then switching operation is simple and fast, but data protection is compromised and connection stability deteriorates
Solution Approach 1:
The switching control is segmented into two independent parts: video signal switching and peripheral device signal switching. The video signal can be switched independently without automatically triggering peripheral device switching, allowing selective control of each signal type to maintain stability while preserving switching capability.
Solution Approach 2:
The system dynamically adjusts the switching behavior based on the state of data communication. When data communication is detected, peripheral device switching is suspended; when no communication is detected, normal switching is enabled. This dynamic adaptation resolves the contradiction between switching speed and connection stability.
2Ease of operation
If peripheral device signal switching is performed in conjunction with video signal switching, then simultaneous control is achieved, but data protection and meeting persistence are compromised
Solution Approach 1:
A discrimination device acts as an intermediary between the switching control and peripheral device connection. It detects whether data communication is in progress and mediates the switching action accordingly, blocking simultaneous switching when communication is active and allowing it when inactive, thus protecting data while maintaining operational simplicity.
Solution Approach 2:
The system uses feedback from the discrimination device about the data communication state to control the switching behavior. The feedback mechanism allows the system to automatically adjust whether simultaneous switching occurs based on real-time communication status, ensuring data protection without complicating user operation.
3Adaptability or versatility
If peripheral device connection is switched with video signal input, then resource utilization is optimized, but connection port usage stability deteriorates
Solution Approach 1:
The connection port switching behavior is made dynamic based on communication state detection. The system adaptively changes between two modes: suspended switching when data communication is active (maintaining stability) and normal switching when inactive (optimizing resource utilization). This dynamic behavior resolves the contradiction between adaptability and stability.

AI summary
A display apparatus comprises a peripheral device signal switcher that selects and switches a data communication destination of a peripheral device connector between an internal computer and an external computer device in conjunction with switching of an input source of a video signal by a video signal switcher in such a way that a data communication destination of the peripheral device connector becomes identical to the input source of the video signal, in a case where switching of the input source of the video signal by the video signal switcher is performed, wherein the peripheral device signal switcher suspends switching of the data communication destination of the peripheral device connector without switching the data communication destination of the peripheral device connector in conjunction with switching by the peripheral device signal switcher, in a case where a discriminator discriminates that a peripheral device connection port is in data communication.
