Virtual Desktop Multimedia Redirection via QR Code Scanning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users accessing virtual desktops via client devices often lack built-in multimedia accessories, making it cumbersome to use multimedia features like cameras and microphones, especially in scenarios requiring frequent or rapid movement, such as video conferences.
Innovation Solution
The virtual desktop client device employs image scanning techniques to redirect multimedia streams from nearby mobile devices, such as smartphones or tablets, using QR codes, allowing the client device to utilize the mobile device's camera and microphone without the need for pre-installed software, and also redirects audio streams from the virtual desktop to the mobile device for playback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the client device is equipped with built-in multimedia accessories, then multimedia capability is available, but the device structure becomes cumbersome and less mobile
Solution Approach 1:
The patent introduces a mobile device as an intermediary to provide multimedia capabilities. The mobile device captures multimedia streams and transmits them to the client device via QR code connection, allowing the client device to access camera and microphone functions without having built-in hardware. This resolves the contradiction by externalizing the multimedia accessories to a separate mobile device.
2Adaptability or versatility
If RTAV is used to redirect multimedia streams, then virtual desktop multimedia access is enabled, but pre-installed software on the mobile device is required
Solution Approach 1:
The patent enables the mobile device to self-configure and connect to the virtual desktop without requiring pre-installed specialized software. The mobile device uses its existing camera and microphone capabilities along with standard QR code scanning functionality to establish the connection and redirect multimedia streams automatically, eliminating the need for additional software installation.
Solution Approach 2:
The patent leverages universal functionalities already present in mobile devices (camera, microphone, QR code scanning) to achieve virtual desktop multimedia access. By using these existing multi-purpose features rather than dedicated multimedia software, the system enables virtual desktop integration without requiring device-specific or pre-installed applications.
3Device complexity
If the client device lacks built-in multimedia accessories, then device simplicity is maintained, but multimedia activities cannot be performed
Solution Approach 1:
The patent introduces a mobile device as an intermediary to bridge the gap between the simple client device and multimedia requirements. The mobile device captures multimedia streams and transmits them to the client device via QR code connection, allowing the client device to access camera and microphone functions without having built-in hardware. This resolves the contradiction by externalizing the multimedia accessories to a separate mobile device.

AI summary
A system for multimedia redirection where a virtual desktop client device can utilize the multimedia accessories such as digital camera(s) and/or microphone(s) of nearby mobile devices by utilizing image scanning techniques. The mobile device contains a web browser and image scanning technology, such as a QR code reader. The mobile device scans a QR code displayed by the virtual desktop client device and establishes a connection with a web server on the virtual desktop client device. The multimedia stream captured by the multimedia accessories of the mobile device is streamed to the virtual desktop client device using the connection and is redirected by the virtual desktop client device to the virtual desktop. The virtual desktop client device may also redirect multimedia, such as an audio-out stream received from the virtual desktop, to the mobile device in order to playback audio using the speaker of the mobile device.
