Remote Application Display via Video Router in Vehicles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Security concerns and certification challenges hinder the hosting of browsers and applications on high design assurance level systems in vehicles, exposing them to cyber-security risks and complicating updates.
Innovation Solution
A system and method for displaying a remotely executed application on a vehicle's display, using a video router to combine and selectively display video signals from onboard and remote sources, enabling two-way video and audio transmission, and allowing remote control and maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If browsers and applications are hosted on high design assurance level systems in vehicles, then access to critical information and running programs is enabled, but security risks and certification challenges increase
Solution Approach 1:
The patent introduces a remote server as an intermediary between the vehicle's display system and the Internet. The server hosts browsers and applications remotely, allowing the vehicle system to access critical information without directly running uncertified software on high assurance level systems. This mediator approach enables information access while maintaining security boundaries.
2Adaptability or versatility
If browsers and applications are hosted on high design assurance level systems, then application functionality is available, but certification difficulty increases due to constant churn of features and data
Solution Approach 1:
By placing the browser and application hosting on a remote server rather than on the vehicle's certified system, the patent eliminates the certification burden from the vehicle system. The server can freely update and change application features without affecting the certification status of the vehicle's high assurance level systems.
Solution Approach 2:
The system separates the application hosting function from the vehicle's core system. The remote server handles the dynamic, frequently-changing application layer, while the vehicle system maintains its certified, stable core functions. This segmentation allows independent updates without recertification.
3Productivity
If software is hosted on the vehicle system, then local access is enabled, but update complexity increases due to individual vehicle updates required
Solution Approach 1:
The remote server acts as a centralized update point for all vehicles. Software updates, browser upgrades, and application changes are deployed to the server once and automatically made available to all connected vehicles. This eliminates the need to individually update each vehicle system, dramatically reducing update time and complexity.
4Reliability
If browsers are hosted offboard on remote servers, then security risks are reduced, but access to critical information may be limited
Solution Approach 1:
The remote server provides secure access to critical information by acting as a controlled intermediary. It can filter and manage what information is made available to vehicles while maintaining security boundaries. The system enables access to flight path information, weather, and other critical data without compromising the vehicle's security architecture.
Data Source
AI summary
Systems and methods for displaying and controlling a remotely executed application on a display of a vehicle are disclosed. A method may include: receiving, by one or more processors, one or more video signals from one or more video sources onboard the vehicle; receiving, by the one or more processors, at a client module, a video signal including an image or display of the application executing on a remote server through a network; combining, by the one or more processors, via a video router, the received one or more video signals from the one or more video sources onboard the vehicle and the video signal including the image or display of the application executing on the remote server; and selectively displaying, by the one or more processors, on a display of the vehicle, the video signal including the image or display of the application executing on the remote server.
