Solution Overview
Problem
Current methods for broadcasting live video from remote locations, such as news events, face challenges in ensuring reliable and high-quality transmission over varying network conditions, particularly in areas with limited bandwidth.
Innovation Solution
A bonded transmission device that receives a live video signal, divides it into multiple transmissions, and broadcasts these over a wide area network using a combination of cellular, Wi-Fi, and other wireless transmitters, allowing for redundant data transmission and dynamic adjustment of video parameters to maintain quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If live video is transmitted over a single network path, then the transmission setup is simple, but the reliability deteriorates under limited bandwidth or network failures
Solution Approach 1:
The patent segments the video stream into multiple independent transmission paths (cellular, Wi-Fi, wired connections). Each path carries a portion of the video data, and the system combines these segments at the receiving end. This segmentation allows the video transmission to bypass network failures by routing through alternative paths, thereby improving reliability without requiring a completely complex redundant system.
Solution Approach 2:
The patent merges multiple transmission paths into a single unified video stream. The bonded transmission device combines video feeds from multiple encoders that are transmitted over different network paths (cellular, Wi-Fi, Ethernet) and reconstructs them into a single high-quality video output. This merging approach maintains reliability by having multiple paths while presenting a simple single-stream interface to the end user.
2Productivity
If multiple transmitters are used for bonded transmission, then the bandwidth and reliability improve, but the device complexity increases
Solution Approach 1:
The bonded transmission device is designed as a universal platform that can interface with multiple types of transmitters (cellular modems, Wi-Fi cards, wired network interfaces) through standardized protocols. This multi-functionality allows the system to leverage various available network connections for video transmission, increasing effective bandwidth while maintaining a consistent, manageable device architecture that doesn't require separate complex handling for each transmitter type.
3Manufacturing precision
If video parameters are dynamically adjusted to maintain quality, then the video quality is preserved, but the processing complexity increases
Solution Approach 1:
The system implements feedback mechanisms where the bonded transmission device continuously monitors the quality and status of each transmission path. Based on this feedback, the system dynamically adjusts video parameters such as bitrate, resolution, and encoding quality for each path. This feedback-driven approach maintains high video quality by adapting to real-time network conditions while using automated algorithms that reduce the need for manual processing complexity.
