Display Device Video Switch Inhibition Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display devices compatible with one-touch play functions may involuntarily switch to displaying AV signals from recently activated devices, disrupting currently watched videos, and users must manually select between display and information devices, leading to inconvenience and increased labor.
Innovation Solution
A display device system that inhibits the display of a video signal from one video signal output device when a switch instruction is received from another device, only if the current device is actively displaying a video signal, ensuring that the current video is not interrupted unless the power or playback status of the active device changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the display device automatically switches to display video signals from recently activated devices according to one-touch play function, then the ease of operation is improved, but the reliability of currently displayed video is deteriorated due to involuntary switching
Solution Approach 1:
The display device applies preliminary anti-action by proactively preventing the automatic switching action before it can disrupt the currently displayed video. The determining unit checks whether switching would cause disruption, and the inhibiting unit blocks the switching action in advance when disruption is detected, thus maintaining video reliability while preserving one-touch play functionality for appropriate cases
Solution Approach 2:
The invention introduces an intermediary control mechanism between the one-touch play function and the video display switching. The determining unit acts as an intermediary that evaluates switching conditions, and the inhibiting unit serves as a mediator that selectively blocks or allows switching based on this evaluation, thereby resolving the conflict between automatic switching convenience and video display stability
2Reliability
If the display device allows manual selection between display device and information device, then the reliability of device usage is improved, but the loss of time increases due to manual selection requirement
Solution Approach 1:
The invention applies partial action by implementing manual selection only in specific cases where automatic switching would cause disruption. When no disruption is detected, the system automatically switches without requiring manual selection, thus reducing time loss. Manual selection is partially applied only when necessary to maintain reliability
Solution Approach 2:
The system dynamically adjusts its behavior based on the current display state and device activation status. The control mechanism transitions between automatic switching mode and manual selection mode depending on whether switching would disrupt currently displayed video, thereby optimizing both response time and reliability according to real-time conditions

AI summary
A display device is connectible to a first video signal output device and a second video signal output device. Upon receiving an input switch instruction from the first video signal output device, the display device is configured to inhibit a first video from the first video signal output device from being displayed when displaying a second video from the second video signal output device.
