Vehicle Mirror Link Independent Screen Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems lack the ability to independently control and output multimedia content from both vehicle AVN systems and portable terminals, limiting user flexibility in accessing and displaying multimedia information during vehicle use.
Innovation Solution
A method that connects a vehicle's multimedia system to a portable terminal, executes a mirror link application, and outputs a menu for user selection to control the image output, allowing independent operation of the AVN and portable terminal screens, with vehicle information transmitted using the SetParameter protocol in RTSP, enabling customized user interfaces and remote data storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single protocol is used for transmission, then the system complexity is reduced, but the ability to independently control and stream multimedia content is limited
Solution Approach 1:
The patent makes the mirror link connection multi-functional by enabling it to handle both traditional mirror link content (application execution) and vehicle information transmission (via SetParameter protocol) through the same communication channel. This allows the system to maintain low complexity while achieving versatile multimedia control and independent content streaming.

AI summary
A system and method of controlling a mirror link are provided. The method includes connecting, by a controller, a multimedia system mounted within a vehicle to a portable terminal and executing an application to perform the mirror link. In addition, a menu is output to independently control an output image of the multimedia system and the portable terminal to the vehicle. The controller is also configured to independently control the output image of the multimedia system and the portable terminal based on a user selection.
