Virtual Set Top Box for Secure IPTV Streaming
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional pay television systems require installation of private distribution networks and hardware-based set top boxes for endpoint control, limiting flexibility and security, and are not well-suited for delivering high-quality streaming video over the public Internet with premium quality of service and endpoint control.
Innovation Solution
A communication system utilizing an Internet-based Virtual Private Network (VPN) that encodes signals into TCP/IP packets, manages network traffic, and uses proprietary software to provide a virtual set top box (VSTB) for secure, high-quality streaming video delivery over the public Internet, enabling endpoint control and value-added services like on-demand content and targeted advertisements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional cable television systems use private distribution networks and hardware-based set top boxes for endpoint control, then security and reliability are improved, but device complexity and installation cost increase
Solution Approach 1:
The patent replaces physical hardware-based set top boxes with a virtual set top box implemented as software on general-purpose computing devices. This virtualization approach maintains the endpoint control functionality while eliminating the need for specialized hardware infrastructure, thereby reducing device complexity while preserving security and reliability through software-based authentication and control mechanisms
Solution Approach 2:
The patent substitutes the mechanical/hardware-based set top box system with a software-based virtual set top box running on standard computing platforms. This replacement uses software protocols and digital authentication rather than physical hardware components, reducing installation complexity and hardware requirements while maintaining the essential endpoint control and security functions
2Reliability
If traditional cable television systems deploy extensive private network infrastructure for last-mile delivery, then service reliability is improved, but ease of manufacture and deployment worsen
Solution Approach 1:
The patent enables the system to operate over existing public IP networks (such as broadband internet connections) rather than requiring dedicated private network infrastructure. The virtual set top box can function across multiple network types and delivery scenarios, allowing the same service to be deployed over existing infrastructure while maintaining reliable service delivery through protocol-level security and quality of service mechanisms
Solution Approach 2:
The patent introduces a gateway device that acts as an intermediary between the public IP network and the virtual set top box. This gateway provides network address translation, authentication, and protocol conversion, enabling reliable service delivery over public networks without requiring direct private network infrastructure to reach the customer premises
3Reliability
If traditional systems use hardware-based set top boxes for endpoint control, then security is improved, but adaptability and flexibility worsen
Solution Approach 1:
The patent implements a dynamic, software-based virtual set top box that can be easily configured, updated, and adapted through software modifications rather than hardware changes. This allows the system to adapt to different service requirements, network conditions, and security protocols while maintaining robust endpoint control through software-based authentication and authorization mechanisms
