IPTV Stream Encryption via CDN for Provider-Independent Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Consumers are limited to television services provided by local cable or fiber optic providers due to geographic monopolies, restricting access to desired television service providers regardless of location.
Innovation Solution
A content delivery network encrypts individual television streams from various providers and transmits them over secure communication channels to consumer devices via the Internet, maintaining a one-to-one correspondence between consumers and providers, allowing access to any television service regardless of geographic location.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If local cable or fiber optic providers maintain geographic monopolies, then they can provide television service within their area, but consumers are limited to local providers and cannot access desired television service providers from other locations
Solution Approach 1:
The patent introduces a content delivery network as an intermediary between television service providers and consumers. This network receives encrypted television streams from providers and re-transmits them to consumers regardless of geographic location, thereby enabling consumer access to any provider while maintaining provider restrictions through encryption keys.
Solution Approach 2:
The patent creates a copy of the television service delivery system that operates independently of local monopolies. By copying the encryption and decryption mechanisms, the system allows consumers to access provider content through the Internet without needing physical cable infrastructure in their location.
2Adaptability or versatility
If the content delivery network encrypts individual television streams and transmits them over secure channels, then consumers can access any provider globally while maintaining one-to-one correspondence, but the system complexity increases
Solution Approach 1:
The patent segments the content delivery network into distinct functional components: encryption processors that work with specific providers, decryption processors at consumer devices, and secure communication channels. This segmentation allows the complex system to manage multiple providers independently while maintaining security and correspondence.
Solution Approach 2:
The patent changes the transmission parameter from physical cable connection to encrypted data stream over Internet protocol. This parameter change enables global access while maintaining security through encryption keys, transforming the delivery mechanism without requiring physical infrastructure changes at consumer locations.
3Reliability
If the system maintains one-to-one correspondence between consumers and providers through encryption, then unauthorized access is prevented, but the complexity of managing secure communication channels increases
Solution Approach 1:
The patent implements preliminary encryption of television streams at the provider end before transmission. Encryption keys are pre-established and managed by the content delivery network, allowing secure one-to-one correspondence to be maintained automatically during transmission without requiring complex real-time authentication for each viewing session.
Data Source
AI summary
A system, method, and apparatus for Internet Protocol television streaming are disclosed. An example apparatus includes a remote access point that provides line termination for television programming received via a data feed from a television service provider. The remote access point is specifically assigned to a client device for maintaining a one-to-one correspondence between the client device and the data feed from the television service provider.
