Audio Device Screen Display Adaptation via Stored Information
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing audio systems cannot display a screen using screen information stored in the device when a video signal is input, even if applications are prioritized, due to limitations in existing technologies.
Innovation Solution
An audio device and system that includes a display unit, screen information storage, an acceptance unit for application selection, and a communication unit to send and receive selection information, allowing the display of screens based on stored application information, enabling the display of screens using screen information stored in the audio device when a video signal is input.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If video signal input from portable terminal is displayed directly, then video output functionality is achieved, but the audio device cannot display screens using its own stored screen information based on application selection
Solution Approach 1:
The audio device pre-stores screen information for multiple applications in advance. When a video signal is input, the system can selectively display either the incoming video signal or the pre-stored screen information based on application priority, enabling flexible screen display adaptation without requiring complex real-time processing
Solution Approach 2:
The control unit acts as an intermediary that receives both video signals from the portable terminal and application selection information from the operation unit. It mediates between these inputs and the display unit, deciding whether to display the video signal or the pre-stored screen information based on application priority, thus resolving the contradiction between video output functionality and screen information adaptability
2Ease of operation
If application priority is set in advance, then sound output priority is determined, but screen display based on application selection is not possible when video signal is input
Solution Approach 1:
The audio device is designed with multi-functionality to handle both audio output and screen display. The display unit can display either video signals from the portable terminal or pre-stored screen information from the audio device, depending on the application priority. This universal design allows the system to maintain screen information display capability while also supporting video signal input, resolving the contradiction between ease of operation and information display capability
3Productivity
If the display unit shows video signal from portable terminal, then video output is achieved, but stored screen information cannot be utilized
Solution Approach 1:
The display unit operates dynamically, switching between displaying video signals from the portable terminal and displaying pre-stored screen information from the audio device. The control unit determines the display content based on application priority and operation unit input, allowing the system to utilize stored screen information while maintaining efficient video output capability when needed

AI summary
An audio device comprises a display unit which displays information, a screen information storage unit which stores screen information of a predetermined application, an acceptance unit which accepts a selection of an application, a selection information storage unit which stores selection information of the application accepted by the acceptance unit, an audio device communication unit which sends the application selection information to the portable terminal and receives information according to the application selection information, and a screen display control unit which, upon receiving information according to the application selection information from the audio device communication unit, displays on the display unit a screen using the screen information stored in the screen information storage unit based on the application selection information stored in the selection information storage unit.
