Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional network conferencing platforms face challenges in managing video quality, controlling content, and ensuring interactivity, particularly due to bandwidth issues and the risk of accidental sharing of confidential information during screen sharing, which can lead to connection problems, lag, and limited interactive capabilities.

Innovation Solution

A remote computing server is used to load and stream presentation materials, allowing for real-time control and interaction, with a control data channel between the presenter's device and the server, enabling interactive events to be captured and replayed, and using WebRTC to reduce latency, thus alleviating bandwidth burdens on the presenter's device and enhancing content control and interactivity.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If screen sharing is used for presentation, then the presenter can share content with viewers, but the presenter's device experiences bandwidth burden and processing power strain

Engineering Contradiction:

Improvecontent sharing capabilityVSAvoidbandwidth consumption and processing power

Core Design Contradiction:

Ease of operationVSLoss of energy

Solution Approach 1:

The patent extracts the content rendering function from the presenter's device and relocates it to a remote server. The presenter's device only needs to capture and transmit the final rendered output, while the computationally intensive tasks of content rendering, video encoding, and resource management are performed on the remote server, thereby reducing bandwidth consumption and processing power requirements at the presenter's end.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent introduces a remote server as an intermediary between the presenter's device and the viewers. This intermediary handles the computationally intensive tasks of content rendering, video encoding, and resource management, allowing the presenter's device to operate with reduced bandwidth and processing requirements while still delivering high-quality presentations to multiple viewers.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of operation

If screen sharing is used for presentation, then the presenter can display content, but confidential information may be accidentally exposed

Engineering Contradiction:

Improvecontent display capabilityVSAvoidconfidential information leakage

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

Inventive Principle:

Principle #24Intermediary (Mediator)

3Adaptability or versatility

If conventional network conferencing is used, then basic presentation can be conducted, but interactivity and multimedia content are limited

Engineering Contradiction:

Improvepresentation interactivityVSAvoidsystem architecture complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent enables the remote server to autonomously render content, manage resources, and handle video encoding without requiring complex local infrastructure at the presenter's device. The server independently manages the presentation delivery, automatically adapting to different viewer capabilities and network conditions, thereby simplifying the overall system architecture while enhancing interactivity and multimedia support.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent makes the remote server a universal platform that can handle various presentation formats, interactive content, and multimedia elements. The server architecture is designed to support diverse content types and delivery scenarios, making the system adaptable to different presentation needs without requiring separate specialized infrastructure for each use case.

Inventive Principle:

Principle #6Universality (Multi-functionality)

4Productivity

If presenter's device capabilities are used for presentation, then the presentation is limited by device capacity, but using external resources increases system complexity

Engineering Contradiction:

Improvepresentation quality and interactivityVSAvoidsystem architecture complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

Inventive Principle:

Principle #6Universality (Multi-functionality)

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.
