Display Input Auto-Switching for Multi-Port Video Source Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulties in selecting the correct video source among multiple AV connection ports on multimedia devices, often leading to incorrect connections due to the similarity in appearance of connectors, especially when devices like televisions are not easily accessible.
Innovation Solution
A display with a control chip that detects activity at AV connection ports to determine active sources and prioritizes them, allowing for automatic configuration and display of images from the highest priority sources, either singularly or in picture-in-picture mode, thereby simplifying the selection process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple AV connection ports are provided to support various video sources, then the adaptability and versatility of the display device is improved, but the device complexity and difficulty of source selection increases
Solution Approach 1:
The display device automatically detects which AV connection port has an active signal source and switches to display from that port without requiring manual user intervention. The system self-determines the active source by monitoring signal presence on each connection port, thereby simplifying the user experience while maintaining support for multiple video sources
Solution Approach 2:
The system uses visual indicators (such as LED lights or on-screen displays) to show the status of different connection ports, indicating which port is currently active or has a signal present. This visual feedback helps users understand the system's state and locate the active source quickly
2Adaptability or versatility
If multiple AV connection ports with similar appearance are installed, then the adaptability is improved, but the ease of operation deteriorates due to wrong connections
Solution Approach 1:
Different connection ports are equipped with visual indicators that change color or illuminate to show their operational status. This allows users to quickly identify which port is active or has a signal, preventing wrong connections even when ports have similar appearances
Solution Approach 2:
The system provides real-time feedback through visual indicators to show users the status of each connection port. This feedback mechanism helps users verify correct connections and understand which source is currently being displayed, reducing connection errors
3Ease of operation
If manual source selection is required, then the ease of operation is maintained for simple cases, but the loss of time increases when switching between sources
Solution Approach 1:
The display device automatically monitors all AV connection ports and autonomously switches to the active source without requiring manual user input. This eliminates the time users would spend manually selecting sources while maintaining the ability to support multiple video inputs
Solution Approach 2:
The system continuously monitors the status of all connection ports in advance, detecting signal presence before user interaction is needed. This preliminary detection enables instant switching to the active source when it becomes available, eliminating delays
Data Source
AI summary
A method of intelligently selecting a signal source and associated apparatus is provided. The method comprises the following steps. A display is activated. The display detects activities of a plurality of connection ports to determine at least one active video source. The display displays an image according to the at least one active video source and/or a priority. The connection ports can be an HDMI port, a DVI port, an A/V port or a Y/Pb/Pr port.
