Secondary Device Screen Streaming for Mobile Web Conferencing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile devices with limited operating systems and computing resources face challenges in sharing content within web conferencing applications, making online meetings and associated features unavailable.
Innovation Solution
Implementing a streaming receiver integrated into a web conferencing client that allows a secondary mobile device to transmit its screen content to a primary device, which then shares it with other participants as if it were the primary device, leveraging protocols like AirPlay, Miracast, or Play To.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If mobile devices with limited operating systems and computing resources attempt to share content directly in web conferencing applications, then content sharing functionality is desired, but processing and memory constraints prevent successful implementation
Solution Approach 1:
A gateway device is introduced as an intermediary between the mobile device and the web conferencing application. The gateway receives content from the mobile device, processes it, and transmits it to the conferencing system, thereby shielding the mobile device's computational limitations from the complex content sharing requirements.
Solution Approach 2:
The content sharing function is segmented into separate components: the mobile device only captures and streams content locally, while the gateway handles the complex tasks of content formatting, encoding, and transmission to the web conferencing application. This division allows each component to operate within its capabilities.
2Adaptability or versatility
If mobile devices attempt to run full web conferencing applications, then participation is enabled, but processing and memory constraints limit functionality
Solution Approach 1:
The computationally intensive portions of the web conferencing application are extracted and relocated to the gateway device. The mobile device only needs to perform simple content capture and local streaming, while the gateway handles the complex video encoding, audio processing, and network communication protocols required for web conferencing.
Solution Approach 2:
The gateway acts as a mediator that bridges the capability gap between the mobile device and the full web conferencing system. It receives simplified input from the mobile device and transforms it into the complex output required by the conferencing application, enabling mobile participation without requiring the mobile device to run the full application.
3Ease of operation
If screen content is streamed from mobile device to primary device, then content sharing is enabled, but network bandwidth and transmission stability become critical factors
Solution Approach 1:
The gateway dynamically adjusts streaming parameters such as video resolution, frame rate, and compression level based on network conditions. When network bandwidth is limited or unstable, the gateway automatically reduces video quality parameters to maintain continuous transmission, ensuring reliable content sharing under varying network conditions.
