Content Delivery System Using Peer-to-Peer Networks for Satellite Resource Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Satellite television systems face inefficiencies in delivering content to a small audience, as broadcasting to multiple users simultaneously is costly and may not be cost-effective, and there is a need for secure authorization and storage methods to reduce piracy.
Innovation Solution
A content delivery system that allows content to be downloaded and stored on user devices, using various communication means, including satellites, with secure authorization and peer-to-peer networks to manage content distribution, ensuring secure and efficient delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If satellite broadcasting is used to deliver content to multiple users simultaneously, then content delivery capability is improved, but satellite resource consumption and cost increase
Solution Approach 1:
The patent segments content delivery into two distinct modes: satellite broadcasting for initial content distribution and terrestrial peer-to-peer networks for subsequent content sharing. This segmentation allows the satellite to deliver content once to multiple receivers, after which local terrestrial networks handle further distribution, reducing repeated satellite resource consumption while maintaining high content delivery capability.
2Adaptability or versatility
If satellite broadcasting is used to provide content access, then content availability is improved, but cost-effectiveness deteriorates for small audiences
Solution Approach 1:
The patent implements a dynamic content delivery system that adapts the distribution method based on audience size and content sharing needs. For small audiences or localized content sharing, the system dynamically switches from satellite broadcasting to terrestrial peer-to-peer networks, improving cost-effectiveness while maintaining content availability through multiple delivery pathways.
3Productivity
If content is made accessible to multiple users, then content distribution capability is improved, but security against piracy deteriorates
Solution Approach 1:
The patent introduces terrestrial peer-to-peer networks as an intermediary layer between satellite broadcasting and end-user devices. This intermediary enables secure, authenticated content sharing among authorized users locally, maintaining security controls while facilitating widespread content distribution. The peer-to-peer network acts as a controlled intermediary that prevents unauthorized access while enabling legitimate content sharing.
