Distributed Media Sharing via Overlay Network
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing media sharing systems across broadcast operation centers are prone to single-point failures and require manual checks, limiting scalability and reliability, as they often rely on central databases and pre-defined site configurations.
Innovation Solution
A media sharing system utilizing an overlay network with media brokers that provides a global view of media assets and automates content distribution among peer sites, eliminating the need for a central database and allowing dynamic site participation, thereby ensuring continuous availability of media content even in the event of site failures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a central database or central server is used for media sharing, then media content can be distributed to multiple sites, but the system creates a single point of failure and requires all sites to be known a-priori
Solution Approach 1:
The patent divides the centralized media sharing system into multiple distributed peer nodes. Each peer maintains its own media inventory and can independently serve other peers, eliminating the central server single point of failure. The system segments the functionality of content storage, indexing, and distribution across multiple independent nodes that collectively provide the same service.
Solution Approach 2:
The patent introduces a peer-to-peer overlay network as an intermediary layer between media sources and consumers. This overlay network enables direct peer-to-peer content sharing while maintaining a global view of media assets through distributed routing protocols, allowing dynamic site participation without requiring pre-defined configurations.
2Adaptability or versatility
If manual checks are performed to determine media needs at each site, then media sharing can be implemented, but the process is inefficient and does not provide a global view of media asset needs
Solution Approach 1:
The patent implements continuous feedback mechanisms where peers periodically exchange inventory information and media needs through the overlay network. This distributed feedback loop enables the system to maintain a global view of media assets without central coordination, automatically adapting to changing needs and availability across the network.
Solution Approach 2:
Each peer node autonomously determines its own media needs and independently searches the distributed network for available content. Peers self-configure and self-manage their participation in the media sharing system, eliminating the need for manual checks and centralized assignment of media assets.
3Device complexity
If all sites are required to be known a-priori, then system configuration is simplified, but the system lacks scalability and flexibility for dynamic participation
Solution Approach 1:
The patent creates a dynamic peer-to-peer network where sites can join and leave the media sharing system at any time without requiring pre-registration or reconfiguration. The overlay network dynamically routes requests and updates inventory information in real-time, allowing the system to adapt to changing network topology and participant availability.

AI summary
A media content sharing system includes multiple broadcast operation centers that together are configured to automatically acquire and distribute media content among one another based upon the media content needs and inventories of each participating broadcast operation center. The media sharing system architecture eliminates any single-point of system failure such that an inventory of media content corresponding to a particular broadcast operation center remains available to broadcast operation centers remaining on the media content sharing system subsequent to failure of the particular broadcast operation center.
