Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication systems face challenges in enabling secure and seamless communication between devices with incompatible protocols, limiting their ability to support multimedia services like streaming media over multiple channels simultaneously.
Innovation Solution
The implementation of a wireless communication system that utilizes multiple transceivers and communication pathways with different protocols to establish secure media sessions, where one pathway carries encrypted I-Frame video frames and another carries unencrypted or differently encrypted P-Frame/B-Frame frames, ensuring secure transmission by requiring interception of multiple channels for signal reconstruction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple communication channels with different protocols are used to transmit video frames, then security against eavesdropping is improved, but device complexity increases
Solution Approach 1:
The patent segments the video stream into different types of frames (I-frames and P-frames/B-frames) and transmits them through separate communication channels with different protocols. This segmentation allows the system to achieve security through diversity without requiring all data to be encrypted through complex multi-layer protocols, thus resolving the contradiction between security improvement and device complexity.
Solution Approach 2:
The patent applies different encryption and protocol characteristics to different parts of the video stream locally. I-frames are transmitted over one channel with specific security measures while P-frames/B-frames use another channel with different measures. This local differentiation optimizes security without uniformly increasing complexity across the entire transmission system.
2Reliability
If encryption is applied to all communication channels, then security is improved, but transmission speed decreases due to processing overhead
Solution Approach 1:
Instead of applying encryption uniformly to all video data, the patent applies partial encryption only where necessary. By transmitting P-frames/B-frames through a second channel that may not require the same level of encryption as I-frames, the system achieves adequate security without the processing overhead of encrypting every frame, thus maintaining transmission speed.
Solution Approach 2:
The patent changes the encryption parameters and protocol characteristics based on the frame type and transmission requirements. Different frames receive different levels of security protection, allowing the system to optimize between security and speed by adjusting encryption intensity to match the actual risk and performance needs of each data segment.
3Device complexity
If a single communication protocol is used for all channels, then device complexity is reduced, but adaptability to different network environments decreases
Solution Approach 1:
The patent implements a multi-functional communication system where the device can operate using multiple different communication protocols simultaneously across different channels. This universality allows the system to adapt to various network environments (wireless, wired, different security requirements) while managing complexity through a standardized framework for handling multiple protocols, rather than requiring completely separate systems for each protocol type.

AI summary
A method and apparatus support delivering a video media stream to a wireless device by exchanging communication signals through a secure communications interface to establish first and second communication channels. The channels may be according to different communication protocols. A first portion of the streamed video media stream over the first communication channel is encrypted while a second portion of the video media stream over the second communication channel is not encrypted. The second portion is based on the first. In addition to encryption of only the first portion, one embodiment includes using different communication protocols for the first and second channels to further enhance secure media delivery.
