Solution Overview
Problem
Current live video streaming technologies face challenges in providing secure and reliable high-quality streams with low latency, especially due to high bandwidth costs associated with conventional cloud-based services.
Innovation Solution
A decentralized system utilizing blockchain technology or a centralized stream manager to manage real-time streaming, which includes a network of nodes (broadcaster, origin, relay, edge, and proxy nodes) that securely and reliably stream multimedia content. The system uses logistical regression to select suitable nodes based on geographical position, bandwidth, packet loss, and age, and implements double-layer encryption using WebRTC and DRM keys.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional cloud-based services are used for video streaming, then ease of operation and scalability are improved, but bandwidth costs increase significantly
Solution Approach 1:
The system segments the streaming network into multiple independent nodes (broadcaster nodes, origin nodes, relay nodes, edge nodes) that can operate autonomously. Each node is independently selected and managed, allowing the system to distribute bandwidth requirements across many smaller connections rather than relying on a single centralized cloud provider, thereby reducing overall bandwidth costs while maintaining ease of use through automated node selection.
Solution Approach 2:
The system implements self-service through automated node selection using logistical regression algorithms that automatically identify suitable nodes based on criteria such as geographical position, bandwidth availability, packet loss rates, and age. This automation eliminates the need for manual configuration while optimizing network resources, reducing bandwidth costs without sacrificing operational ease.
2Reliability
If decentralized network nodes are selected based on multiple criteria, then reliability and stream quality are improved, but device complexity increases
Solution Approach 1:
The system transforms complex multi-criteria node selection into a standardized parameter evaluation framework. Logistical regression algorithms convert diverse node attributes (geographical position, bandwidth, packet loss, age) into standardized scoring parameters, automatically ranking nodes based on their performance across these parameters. This approach improves reliability through comprehensive evaluation while managing complexity through algorithmic standardization.
Solution Approach 2:
The patent replaces manual or simple mechanical node selection mechanisms with automated computational algorithms. The logistical regression model substitutes for complex manual evaluation processes, automatically calculating node suitability based on multiple criteria. This substitution reduces operational complexity while enhancing reliability through data-driven, objective node selection.
3Object-affected harmful factors
If multi-layer encryption is implemented for content security, then content protection is improved, but system complexity increases
Solution Approach 1:
The system implements nested encryption layers where WebRTC encryption is applied at the transport layer and DRM encryption is applied at the content layer. This nested structure allows each encryption layer to operate independently with specific functions: WebRTC provides transport security while DRM provides content protection. The modular nested architecture enhances content security without creating a single complex encryption system, as each layer can be managed and implemented separately.
