Communication Control System for Automatic Screen Sharing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing remote conference systems using interactive electronic whiteboards require time-consuming preliminary preparations, such as installing exclusive software and connecting USB and VGA cables, making it difficult to quickly and automatically share the PC screen with remote attendees.
Innovation Solution
A communication control system comprising a first and second control device connected by group identification information, with a detecting unit to capture and send image data from a display unit, and a communication control unit to establish and manage data communication sessions, allowing automatic sharing of image data over a network.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If exclusive software is installed and USB/VGA cables are connected for screen sharing, then reliable screen sharing is achieved, but the preparation time becomes very long
Solution Approach 1:
The interactive electronic whiteboard is designed to universally support multiple connection types (USB, VGA, network connections) and multiple operating modes (direct connection, network-based connection). This multi-functionality allows the system to adapt to different scenarios without requiring exclusive software installation, thereby reducing preparation time while maintaining reliable screen sharing capability across various connection methods
Solution Approach 2:
The system introduces an image processing unit and communication control unit as intermediaries between the connection interface and the display output. These intermediary components automatically handle image capture, processing, and transmission over the network, eliminating the need for manual software installation and cable management while ensuring reliable screen sharing. The intermediary layer abstracts the complexity of different connection types into a unified processing pipeline
2Loss of information
If the entire screen of the PC is shared, then all information is available to remote attendees, but unnecessary portions are displayed wasting bandwidth and attention
Solution Approach 1:
The image processing unit implements local quality processing by identifying and processing only the relevant portions of the screen that need to be shared. Instead of transmitting the entire screen, the system can selectively capture and transmit specific regions or applications, reducing bandwidth consumption while ensuring that all necessary information is conveyed to remote attendees. This localized approach optimizes the balance between information completeness and resource efficiency
3Reliability
If manual setup procedures are followed for remote conference, then system compatibility is ensured, but the ease of operation is reduced
Solution Approach 1:
The communication control unit implements self-service functionality by automatically detecting the connection type, initiating the appropriate communication protocol, and configuring the screen sharing parameters without user intervention. The system autonomously manages the entire setup process, from connection detection to establishing the communication session, thereby maintaining system compatibility across different connection methods while dramatically improving ease of operation. Users simply need to connect the device, and the system handles all subsequent configuration automatically
