Vehicle Entertainment System Remote Video Control via Mobile Wireless Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle entertainment systems lack remote control capabilities, making it difficult for users to manage video content across multiple monitors without direct access, especially for users who cannot physically interact with the monitors, such as children in rear seats.
Innovation Solution
A vehicle entertainment system that includes a mobile wireless device (MWD) with a display and circuitry to sample and replicate video content from vehicle monitors, allowing remote users to control video content, brightness, and other settings through a peer-to-peer wireless local area network, using apps like Voxx Link for Android and iOS devices to connect and control multiple monitors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a vehicle entertainment system includes multiple video monitors with local control interfaces, then users can control video content at each monitor location, but users cannot remotely control video content from a different location within the vehicle
Solution Approach 1:
The mobile wireless device creates a digital copy of the monitor display by capturing screen shots and transmitting them wirelessly to the MWD. This allows the remote user to view and control the video content on their own device, effectively replicating the monitor's functionality at a different location without adding physical control interfaces to the monitor itself
Solution Approach 2:
The mobile wireless device acts as an intermediary between the user and the video monitor. It receives control inputs from the user, transmits them to the monitor, and relays the display content back to the user, enabling remote control without requiring direct physical access to the monitor's control interface
2Ease of operation
If users can physically interact with monitor control interfaces, then video content can be controlled directly, but users who cannot physically reach or access monitors (e.g., children in rear seats) cannot control the content
Solution Approach 1:
The system creates a visual copy of the monitor display on the mobile wireless device's screen. Users can see what is being displayed on the vehicle monitor through the MWD, and this copied display can be positioned at any location within the vehicle, making the content visible and controllable for users who cannot physically access the original monitor
Solution Approach 2:
The control interface is moved from the physical spatial dimension (requiring the user to be at the monitor's location) to the digital dimension (accessible through the MWD application). This allows users to control video content from any location within the vehicle by interacting with the MWD's touchscreen interface rather than the physical monitor controls
3Adaptability or versatility
If video content is streamed to multiple devices, then remote viewing is enabled, but control capabilities are lost without additional hardware
Solution Approach 1:
The mobile wireless device serves multiple functions: it acts as a remote display for viewing video content, a control interface for managing video playback, and a communication bridge between the user and the vehicle's entertainment system. This multi-functionality eliminates the need for separate hardware devices for viewing and control

AI summary
A vehicle entertainment system may include at least one vehicle video monitor configured to be mounted in the vehicle and including a monitor display and a monitor control interface permitting an adjacent user to control video content for the monitor display. The system may further include a mobile wireless device (MWD) to be carried by a remote user within the vehicle comprising an MWD display and circuitry associated therewith configured to obtain sampled video content being displayed on the monitor display, display the sampled video content on the MWD display, and provide a remote MWD control interface to permit the remote user to remotely control the video content on the monitor display.
