Vehicle Video Audio System Individual Display Sharing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle video/audio systems cannot allow individual users to display different video/audio content, and there is no efficient method for sharing video/audio or navigating maps among users, limiting user experience and driving safety.
Innovation Solution
A system comprising a primary video/audio device with a microprocessor and network interface, and secondary devices with decoding capabilities and operation interfaces, enabling wireless or wired network communication for individual content display and sharing, including a method for recording system status for seamless restarts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a primary device decodes a single video/audio signal source for multiple display panels, then the system structure is simple, but different users cannot watch different video/audio signal sources simultaneously
Solution Approach 1:
The system divides the video/audio processing function into multiple independent decoding devices, each capable of decoding different signal sources. This segmentation allows each display panel to receive independently decoded content, enabling different users to watch different content simultaneously while maintaining individual device independence
Solution Approach 2:
A control device is introduced as an intermediary to manage the networked system. The control device receives user selections and coordinates the decoding and display across multiple devices, enabling individual content selection without requiring direct complex interconnections between all components
2Adaptability or versatility
If display panels are connected via cables to receive video signals, then the connection is stable, but users cannot share media content or navigate maps among themselves
Solution Approach 1:
The system implements a network interface that enables multiple functions including media content sharing and navigation map sharing across all devices. This universal communication interface allows any device to share its displayed content with others, and to receive and display navigation information from any source, eliminating information loss through centralized management
3Reliability
If the system shuts down without recording status, then the operation is simple, but the video/audio display cannot be recovered after restart
Solution Approach 1:
The control device records the status information of each decoding device before shutdown occurs. This preliminary recording action captures which device is displaying which content, enabling the system to automatically restore the previous display configuration after restart without requiring manual reconfiguration
