Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Cloud desktop video conferencing systems face high network bandwidth and server resource consumption due to screenshot-based desktop sharing, leading to poor video display effects.

Innovation Solution

The method involves stripping the display part of the video conference system to the terminal, with video acquisition and playback occurring locally, reducing the need for desktop stream recirculations between the terminal and the cloud desktop.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If screenshot-based desktop sharing is used for video conferencing, then compatibility with various terminals and operating systems is improved, but network bandwidth consumption and server resource usage increase significantly

Engineering Contradiction:

ImprovecompatibilityVSAvoidnetwork bandwidth consumption

Core Design Contradiction:

Adaptability or versatilityVSLoss of energy

Solution Approach 1:

The patent segments the video conference window information into main window information (displayed at terminal) and auxiliary window information (displayed at server). This segmentation allows the terminal to handle display of critical content locally, reducing the amount of data that needs to be transmitted and processed by the server, thereby lowering network bandwidth consumption while maintaining compatibility across different terminals.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent extracts the main window information from the complete desktop stream and displays it directly at the terminal without requiring full screenshot processing. By taking out only the essential video conference content for local display, the system reduces the computational burden on servers and minimizes network bandwidth usage while preserving cross-platform compatibility.

Inventive Principle:

Principle #2Taking out (Extraction)

2Adaptability or versatility

If screenshot-based desktop sharing is used for video conferencing, then compatibility with various terminals and operating systems is improved, but video display quality deteriorates

Engineering Contradiction:

ImprovecompatibilityVSAvoidvideo display quality

Core Design Contradiction:

Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The patent segments video conference window information into main window information (for high-quality local display) and auxiliary window information (for server processing). This segmentation enables the terminal to display critical video content with high quality using local resources, while the server handles auxiliary information, thus improving overall video display quality without sacrificing compatibility.

Inventive Principle:

Principle #1Segmentation

3Reliability

If complete desktop stream is transmitted between terminal and cloud desktop, then video conference functionality is maintained, but server resource consumption increases

Engineering Contradiction:

Improvevideo conference functionalityVSAvoidserver resource consumption

Core Design Contradiction:

ReliabilityVSLoss of energy

Solution Approach 1:

The patent segments the desktop stream processing into two parts: main window information processing at the terminal and auxiliary window information processing at the server. This segmentation reduces server resource consumption by shifting critical display tasks to the terminal while maintaining video conference functionality through coordinated processing of both information types.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent extracts main window information from the complete desktop stream for local processing at the terminal. By taking out and handling critical video content locally, the server's resource burden is significantly reduced while video conference functionality is preserved through the remaining auxiliary information processing at the server.

Inventive Principle:

Principle #2Taking out (Extraction)

4Adaptability or versatility

If screenshot-based desktop sharing is used, then cross-platform compatibility is achieved, but network bandwidth consumption increases

Engineering Contradiction:

Improvecross-platform compatibilityVSAvoidnetwork bandwidth consumption

Core Design Contradiction:

Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

The patent segments video conference information into main and auxiliary components, allowing the terminal to process and display main window information locally with minimal network transmission. This segmentation maintains cross-platform compatibility through standardized information exchange while significantly reducing the quantity of data transmitted over the network.

Inventive Principle:

Principle #1Segmentation
