Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent embeds secure TCP packets (containing HTTPS data) within secure UDP frames, creating a nested packet structure where one protocol is encapsulated within another. This allows the system to maintain TCP's connection-based reliability and security while utilizing UDP's connectionless efficiency for media streaming, thereby preserving security without requiring complex router configurations or additional security equipment

Inventive Principle:

Solution Approach 2:

The patent introduces an intermediary encapsulation layer that translates between TCP and UDP protocols. This intermediary mechanism allows secure data to be transmitted through UDP's simpler protocol without compromising the underlying TCP security features, effectively mediating between the need for security and the desire for implementation simplicity

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

Automated processes, computing systems, computing devices and other aspects of a data processing system provide improved reliability in delivering digital media content over the Internet or a similar wide area network without sacrificing data security. Content is initially placed into a secure format (e.g., secure hypertext transport protocol (HTTPS) via transport control protocol (TCP) or the like). Prior to transmission on the network, the secure data packets are encapsulated within connectionless frames, such as user datagram protocol (UDP) frames. The client device that receives the encapsulated packets extracts the underlying secure content from the connectionless frames for further processing. The encapsulation into connectionless data frames permits client and server devices to establish effective streaming sessions while preserving the security of the underlying data.
