Adaptive Conferencing System Using Media Relay Endpoint
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mesh videoconferencing systems face limitations in bandwidth and endpoint compatibility, leading to reduced quality and impracticality with increasing participants, as they require all endpoints to use the same compression format and have limited computing capacity for handling multiple streams.
Innovation Solution
A novel technique that automatically transitions between different videoconferencing methods (mesh, media relay, and legacy) based on session conditions, using a list of rules embedded in the HTML file, allowing for adaptive switching to avoid bandwidth overload and compatibility issues by utilizing a central entity like MCU or MRM when necessary.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If mesh conferencing is used to handle increased participants, then the system can support more endpoints, but bandwidth consumption increases and quality degrades
Solution Approach 1:
The patent introduces a Media Relay Endpoint (MRE) as an intermediary component that receives media streams from multiple Mesh Conferencing Endpoint Pairs (MCEPs) and relays them to the far end. This mediator architecture allows the system to handle increased participant numbers without proportionally increasing bandwidth consumption at each endpoint, as the MRE consolidates and manages the media relay function centrally.
2Quantity of substance
If mesh conferencing is used to support more participants, then the system capacity increases, but endpoint compatibility requirements become more stringent
Solution Approach 1:
The MRE acts as a compatibility layer between endpoints with different capabilities. By introducing this intermediary, the system can support participants using different compression formats and capabilities without requiring all endpoints to be identical, as the MRE handles the media format conversion and compatibility management.
Solution Approach 2:
The MRE performs multiple functions including media relay, format conversion, and compatibility management in a single component. This multi-functional approach allows the system to support diverse endpoint capabilities while maintaining a unified conferencing architecture.
3Quantity of substance
If mesh conferencing handles increased participants, then system capacity improves, but computing capacity requirements at endpoints increase
Solution Approach 1:
The MRE serves as a computing intermediary that performs media processing functions centrally rather than requiring each endpoint to handle all processing locally. This distribution of computing burden allows endpoints to participate in larger conferences without proportionally increasing their local computing capacity requirements.
4Adaptability or versatility
If automatic transition between conferencing methods is implemented, then system adaptability improves, but system complexity increases
Solution Approach 1:
The system implements dynamic switching between mesh conferencing and media relay conferencing modes based on real-time conditions such as participant count, bandwidth availability, and endpoint compatibility. This dynamic adaptation allows the system to optimize performance for different scenarios while maintaining a unified architecture that manages complexity through automated decision-making.

AI summary
A system and method provide a rule-based technique for adapting a videoconferencing system to current conditions of a conference session, automatically converting the session from one conferencing technique to another, based on those current conditions. Rules may involve criteria including number of participants, ability to use a common codex, among others. An escalation module can be used to manage the transition between one type of conference session and another. If a condition occurs that causes transitioning the conference from one type to another, when that condition no longer applies, the conference may automatically transition back to the original conferencing type.
