Video Conference Screen Sharing With Automatic Participant Confirmation

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

During large video conferences, moderators need to manually check with each participant to confirm successful screen sharing, which is time-consuming.

Innovation Solution

A screen sharing system and method that includes transmitting an identifier and video data to participant devices, allowing them to determine successful sharing by matching the identifier, and sending status codes back to the moderator for confirmation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If manual voice checking is used to confirm screen sharing status with each participant, then the moderator can verify sharing success, but the process becomes time-consuming when the number of participants is large

Engineering Contradiction:

Improvescreen sharing status verificationVSAvoidtime for checking each participant

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The participant's terminal device automatically performs status verification by receiving the identifier, checking it against its own identifier, and autonomously sending the status code back to the moderator without requiring manual intervention from either party

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The system establishes an automatic feedback loop where the participant's terminal device sends status code information back to the moderator's terminal device, providing real-time confirmation of screen sharing status without manual voice checking

Inventive Principle:

Principle #23Feedback

2Loss of information

If the moderator asks each participant by voice whether they successfully see the shared information, then confirmation is obtained, but the process is relatively time-consuming

Engineering Contradiction:

Improveconfirmation of information receptionVSAvoidconference efficiency

Core Design Contradiction:

Loss of informationVSProductivity

Solution Approach 1:

The patent replaces the mechanical voice-based manual checking system with an automated electronic system where terminal devices automatically transmit and process status code information, eliminating the need for time-consuming voice communications

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The status code information acts as an intermediary that automatically conveys screen sharing status from the participant's terminal to the moderator's terminal, replacing the need for direct voice communication and improving information transmission efficiency

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

A screen sharing system and a screen sharing method for a video conference are provided. The screen sharing method includes the following. An identifier is transmitted and video data matching the identifier is transmitted by a first terminal device. Status information corresponding to a second terminal device is received by the first terminal device in response to transmitting the video data. A prompt message is output by the first terminal device according to the status information. The first terminal device determines whether screen sharing with the second terminal device is successful according to the prompt message.
