Video Injection System for Remote Camera Testing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Testers face challenges in remotely testing camera functionalities on websites across various Device-OS combinations, as existing remote testing infrastructure struggles to provide a reliable video viewing solution for camera testing on devices positioned in different geographic locations.
Innovation Solution
A video injection system comprising a user browser, a remote device, and a proxy layer that intercepts web-page responses to inject pre-uploaded video samples when the camera is accessed, allowing the system to stream these samples instead of direct camera feeds, thus enabling effective video testing across multiple remote devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If direct camera streaming is used on remote devices, then real camera functionality can be tested, but video viewing reliability deteriorates when devices are positioned remotely
Solution Approach 1:
The patent introduces a video injection mechanism that acts as an intermediary between the camera hardware and the testing infrastructure. Instead of directly streaming camera output, the system injects pre-recorded video samples into the camera feed pipeline, allowing reliable video testing without requiring optimal physical positioning of remote devices.
2Adaptability or versatility
If remote devices are positioned geographically distributed, then device diversity for testing is improved, but video capture quality deteriorates
Solution Approach 1:
The patent creates copies of video content by injecting pre-recorded video samples into the camera feed. These video copies replace the need for actual camera capture, allowing identical video content to be tested across multiple geographically distributed devices while maintaining consistent video quality regardless of device positioning.
3Ease of operation
If camera functionality is tested on locally positioned devices, then video viewing is straightforward, but remote testing infrastructure capability is underutilized
Solution Approach 1:
The system enables self-service remote testing by automatically injecting video samples into the camera feed without requiring manual intervention. The testing infrastructure serves itself by providing both the test environment and the test content (video samples), allowing testers to efficiently utilize remote devices while maintaining simple video viewing experience.

AI summary
A video injection system comprises a user browser, a remote device, and a proxy layer. The user browser is installed on a user device and is used to log-in and connect to a cloud server that comprises representations of the remote devices. The user browser is used to remotely connect to a remote device, where the remote device uses a remote device's browser to access a website using a network call, which retrieves a web-page response associated with the website. The proxy layer present in the cloud server intercepts the retrieved web-page response and injects a java-script into the retrieved web-page response. When the user accesses a camera of the remote device via the remote device's browser, the injected java-script injects a video sample that was uploaded on a storage platform to the web page response, where the injected video sample is captured by the camera of the remote device.
