On-Demand Video Player for Backup Camera Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing backup camera systems only provide a rear-view when the vehicle is in reverse gear, limiting access to other views such as front or side views, and there is no cost-effective solution to upgrade existing systems to offer on-demand multi-camera views.
Innovation Solution
A backup-camera-system-based on-demand video player that allows drivers to access one or more camera views by controlling the reverse gear indicator signal, enabling on-demand viewing of rear, side, and potentially front views using head movements, voice commands, or touchscreen inputs, without requiring replacement of the existing system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing backup camera systems are used, then the system cost is low, but the system can only provide rear-view when the vehicle is in reverse gear and cannot access other views on-demand
Solution Approach 1:
The invention enables the existing backup camera system to serve multiple functions by allowing on-demand access to different camera views (rear, front, side) through a controller that can redirect video signals to the display monitor regardless of gear position, transforming a single-function system into a multi-functional one without requiring complete system replacement
Solution Approach 2:
The controller acts as an intermediary device that receives video signals from multiple camera sources and selectively routes them to the display monitor based on driver demand, enabling view switching without requiring the display system itself to be replaced, thus adding versatility while maintaining simplicity
2Adaptability or versatility
If multi-camera views on-demand are implemented, then view access capability is improved, but the system cost increases significantly
Solution Approach 1:
The invention uses the existing display monitor and camera infrastructure, creating a virtual multi-camera system through signal routing rather than physical duplication of expensive components. The controller copies and redirects existing video signals to provide multiple views without requiring additional displays or camera processors
Solution Approach 2:
The solution employs a relatively inexpensive controller unit that can be added to existing systems, replacing the need for expensive complete system replacements. The controller is a cost-effective component that enables multi-camera functionality without requiring investment in premium aftermarket systems
3Ease of operation
If the reverse gear indicator signal is controlled for on-demand viewing, then view access flexibility is improved, but the control system complexity increases
Solution Approach 1:
The system uses the existing reverse gear indicator signal infrastructure to trigger view switching, allowing the system to serve itself by repurposing an existing signal line rather than requiring a completely new control interface. The controller monitors and responds to the existing gear indicator signals to enable on-demand viewing
Data Source
AI summary
A backup-camera-system-based, on-demand video player includes at least one video signal input port, driver interface means operable to receive from a driver information about the driver's selection of a video signal input port from the at least one video signal input port, and a controller operable to receive the information from the driver interface means, determining the video signal input port selected by the driver, making a connection between the video signal input port to a back-camera input port of a backup camera system, and sending a reverse gear engaged signal to a reverse gear port of the backup camera system. The drive accesses a video signal connected to the selected video signal port on a display monitor of the backup camera system.
