Innovation Solution
A gateway device with video ports for direct camera connection, native video compression and livestreaming, data ports for large file transfer, high-quality display, and RF transceivers for multiple network connections, including cellular and satellite networks, with network slicing and SD-WAN capabilities for adaptive connectivity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional gateway devices are used for Internet connection, then basic network connectivity is provided, but real-time file transfer and collaboration functionalities are insufficient for modern movie and VR production
Solution Approach 1:
The gateway device is designed to perform multiple functions: it provides Internet connectivity through WiFi and cellular modems, enables real-time file transfer between cameras and postproduction facilities, supports collaboration tools for multiple users, and facilitates cloud storage integration. This multi-functional design resolves the contradiction by making a single device adaptable to diverse production needs without requiring separate specialized equipment for each function.
2Loss of time
If physical transport of footage by vehicles and airplanes is used, then file transfer between production set and postproduction facilities is achieved, but time and cost are significantly increased
Solution Approach 1:
The patent replaces the mechanical transport system (vehicles and airplanes for physical footage transport) with a digital communication system. The gateway device enables wireless transmission of video files and data packets over Internet and cellular networks, allowing instantaneous or near-instantaneous file transfer between the production set and postproduction facilities, thereby eliminating the need for physical transport and significantly reducing both time and resource consumption.
3Ease of operation
If gateway is located close to production set, then digital file transfer is enabled, but traditional gateways lack the required functionality for movie and VR production needs
Solution Approach 1:
The gateway device incorporates dynamic adaptability through configurable settings that allow it to adjust its functionality based on specific production requirements. It can dynamically allocate bandwidth for different types of data traffic (video files, collaboration data, cloud synchronization), and its software can be updated to support emerging production workflows and formats, making it versatile enough to handle various movie and VR production scenarios while maintaining ease of digital file transfer.
