Remote Server Presentation Streaming for Conferencing Bandwidth Relief
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional network conferencing platforms face challenges in managing video quality, controlling content, and addressing bandwidth issues, particularly when the presenter's network is unstable. Screen sharing disproportionately burdens the presenter's upload bandwidth, leading to connection issues, and lacks effective content control and interactivity.
Innovation Solution
A network conferencing system that utilizes a remote computing server to load and stream presentation materials to client devices, establishing a control data channel for interactive events. This setup allows for real-time sharing using protocols like WebRTC, reducing latency and alleviating bandwidth burdens on the presenter's device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If screen sharing is used for presentation, then the presenter can share their screen with viewers, but the presenter's upload bandwidth is disproportionately burdened leading to connection issues
Solution Approach 1:
The patent extracts the presentation content delivery function from the presenter's device and relocates it to a cloud-based server. The server hosts the presentation content and delivers it directly to viewers, removing the bandwidth burden from the presenter's device while maintaining screen sharing functionality through a different technical approach.
Solution Approach 2:
The patent introduces a cloud server as an intermediary between the presenter and viewers. The server acts as a mediator that receives control signals from the presenter's device, renders the presentation content, and distributes it to all viewers, thereby eliminating the direct bandwidth dependency on the presenter's upload capacity.
2Ease of operation
If screen sharing is used for presentation, then the presenter can share their screen with viewers, but the presenter device's processing power is burdened
Solution Approach 1:
The patent extracts the content rendering and processing functions from the presenter's device and relocates them to a cloud server. The presenter's device only needs to capture screen content and transmit control signals, while the server handles the computationally intensive tasks of rendering and distributing the presentation to multiple viewers.
Solution Approach 2:
The cloud server serves as an intermediary that assumes the processing burden. It receives minimal control data from the presenter's device, performs all necessary rendering and content generation, and distributes the processed content to viewers, thereby freeing the presenter's device from heavy processing requirements.
3Ease of operation
If screen sharing is used for presentation, then the presenter can share their screen with viewers, but content control and interactivity are limited
Solution Approach 1:
The patent implements a universal content delivery platform that supports multiple content types (slides, videos, interactive elements) and delivery methods beyond traditional screen sharing. The server-based architecture enables centralized content management, allowing administrators to control what content is available and how it is presented, while supporting various interactive features that enhance content control and viewer engagement.
Solution Approach 2:
The patent transitions from static screen sharing to a dynamic content delivery system. The server can dynamically generate, modify, and distribute content based on viewer interactions, presentation progress, and administrative controls. This enables real-time content adjustments, interactive elements, and adaptive content delivery that screen sharing cannot provide.
4Productivity
If conventional network conferencing is used, then presentations can be conducted, but video quality and interactivity are compromised
Solution Approach 1:
The patent introduces a specialized content delivery server as an intermediary between the presentation source and viewers. This server is optimized for rendering and distributing high-quality video content, separating the content delivery function from the conferencing platform and enabling superior video quality through dedicated processing and distribution infrastructure.
Data Source
AI summary
A system for holding a network conferencing session may include a remote server and a presenter interface. The remote server may be configured to load a presentation material in a content renderer operated at the remote server and transmit video streams of the presentation material to remote client devices that are in the network conferencing session. The presenter interface may receive one of the video streams and display the presentation material based on data from the one of the video streams. The presenter interface may capture interactive events of a presenter directed at the presenter interface. The presenter interface may transmit the interactive events of the presenter to the remote server for remotely controlling the content renderer operating at the remote server using the interactive events directed at the presenter interface.
