Media Relay Video Image Segmentation for Tele-Education
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In tele-education services based on video conferencing, students often lose concentration due to receiving video images from multiple terminals, and lecturers struggle to adjust content according to varying learning levels without additional application installations.
Innovation Solution
A system and method that includes a media relay to acquire and combine video images from multiple terminals based on user information and conferencing progress stages, providing differently combined images to each terminal, allowing lecturers to adjust content and monitor student states in real-time without requiring separate application installations on student terminals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If video images from all student terminals are combined and provided to all terminals, then the lecturer can check the states of all students, but the students may lose their concentration on the lecture
Solution Approach 1:
The patent applies local quality by providing different video image combinations to different terminals based on their roles. The lecturer's terminal receives comprehensive video images from all students for monitoring, while student terminals receive only the lecturer's video images to maintain concentration. This differentiated approach allows each terminal to receive exactly the visual information it needs for its specific function.
Solution Approach 2:
The video image distribution is segmented by terminal type and role. The system divides the video feed stream into different combinations: one stream for the lecturer containing all student videos, and another stream for students containing only the lecturer's video. This segmentation resolves the contradiction by ensuring each group receives appropriate visual information without interference.
2Productivity
If the same educational content is provided to all users through channel broadcasting, then the service provider can efficiently deliver content, but the content cannot be adjusted according to users' learning levels
Solution Approach 1:
The system dynamically adjusts video image combinations based on user information and conferencing progress stages. During the lecture phase, student terminals receive only the lecturer's video for focused learning. During Q&A phases, the system dynamically includes relevant student video feeds to enable interaction. This dynamic adaptation allows the same content delivery infrastructure to serve different learning needs at different times.
Solution Approach 2:
The video conferencing system serves multiple functions: it acts as both a content delivery platform for lectures and an interactive discussion platform for Q&A sessions. By adjusting video image combinations based on conferencing progress stages, the system universally supports both teaching and learning functions within a single platform, accommodating different learning levels and interaction needs.
3Ease of operation
If lecture materials are shared through separate application programs, then students can access lecture materials, but additional application installations are required on student terminals
Solution Approach 1:
The patent merges the lecture material sharing function with the video conferencing function into a single integrated system. Lecture materials are shared through the video conferencing platform itself rather than requiring separate application programs. This consolidation eliminates the need for additional installations on student terminals while maintaining full lecture material accessibility through the unified video conferencing interface.

AI summary
A system and method for a tele-education service system based on video conferencing are provided. The tele-education service system includes a host terminal to manage a tele-education service system; at least one participating terminal to receive the tele-education service; and a media relay to acquire video images from the host terminal and the at least one participating terminal, to combine the acquired video images differently according to user information of the host terminal and the at least one participating terminal and the progress stages of video conferencing and to provide the differently combined video images to the host terminal and the at least one participating terminal, respectively.
