Scalable WebRTC Media Engine with Virtual Agents
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
WebRTC multi-party interactive sessions face challenges due to the 'full mesh' architecture, which burdens computing resources and bandwidth, and is complicated by variations in WebRTC media stack implementations across different web client types and versions.
Innovation Solution
A scalable WebRTC media engine is introduced that instantiates virtual WebRTC agents, allowing clients to establish interactive flows with these agents, synthesizes content, and directs it back, thereby avoiding the full mesh architecture and resolving compatibility issues between incompatible clients.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a full mesh architecture is used for multi-party WebRTC sessions, then direct peer-to-peer communication is achieved, but computing resources and bandwidth are excessively consumed
Solution Approach 1:
The patent introduces a media server as an intermediary component that receives media streams from multiple WebRTC clients and redistributes them. This mediator architecture replaces the full mesh peer-to-peer connections, significantly reducing the computing resources and bandwidth required while maintaining reliable multi-party communication. The media server handles the complex routing and distribution tasks that would otherwise burden individual client devices.
2Device complexity
If a central media server is implemented for multi-party WebRTC sessions, then architecture complexity is reduced, but compatibility issues arise due to variations in WebRTC media stack implementations
Solution Approach 1:
The patent employs parameter changes by dynamically adjusting media stream parameters (such as codec selection, resolution, and bitrate) based on the capabilities of each WebRTC client. The media server negotiates and adapts these parameters to ensure compatibility across different client types and versions, resolving the compatibility issues that arise from variations in WebRTC media stack implementations while maintaining a simplified central server architecture.
3Adaptability or versatility
If virtual WebRTC agents are instantiated to manage media flows, then client compatibility is improved, but system complexity increases
Solution Approach 1:
The patent creates virtual WebRTC agents as software copies that emulate real WebRTC client behavior. These virtual agents are instantiated on the media server to handle media flows from clients with incompatible media stacks. By copying the essential WebRTC client functionality on the server side, the system achieves broad client compatibility without requiring complex peer-to-peer negotiation between incompatible clients, as the virtual agents serve as standardized intermediaries.
