Video Signal Segmentation for Multi-Path IP Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional video signal transmission systems face challenges in efficiently distributing high-definition and high-volume video signals, such as 4K and 8K, due to limitations in network infrastructure, and existing solutions like link aggregation are impractical and inefficient, especially when dealing with large-scale physical infrastructure and potential path failures.
Innovation Solution
A video signal transmission system that segments video signals into independent IP packets, allocates sequence numbers, and distributes them across multiple transmission paths using a transmitter and receiver configuration with multiple network interfaces, allowing for efficient load distribution and fallback mechanisms in case of path failures.

Engineering Contradiction Analysis
1Productivity
If link aggregation is used to improve communication speed by regarding multiple transmission paths as one, then bit rate is improved, but packets with the same source MAC address are passed through the same transmission path causing inability to achieve proper distribution
Solution Approach 1:
The video signal is segmented into multiple IP packets at the transmitter, with each packet assigned a unique sequence number. This segmentation allows packets to be distributed across multiple transmission paths independently, resolving the link aggregation problem where packets with the same MAC address were forced through the same path.
Solution Approach 2:
The system changes the packet distribution parameter from using MAC address as the sole key to using sequence numbers that incorporate path identification. This parameter change enables packets to be routed through different paths based on their sequence numbers, achieving proper load distribution while maintaining high bit rates.
2Reliability
If link aggregation is implemented over entire paths including from network device to receivers, then transmission reliability is improved, but large-scale physical infrastructure is required making it impractical
Solution Approach 1:
The patent extracts the path distribution function from the physical infrastructure layer and implements it at the IP packet layer through sequence number allocation. This eliminates the need for link aggregation implementation across entire physical paths, reducing infrastructure complexity while maintaining transmission reliability through logical path distribution.
3Reliability
If one transmission path fails in link aggregation, then automatic fallback to remaining paths occurs, but packets cannot be passed over to other virtual transmission paths causing transmission continuity issues
Solution Approach 1:
The system dynamically routes IP packets based on real-time path status. When a transmission path fails, the transmitter detects the failure and dynamically changes the routing of subsequent packets to use only the remaining functional paths, ensuring transmission continuity without requiring manual intervention.
Solution Approach 2:
The system implements feedback mechanisms where the transmitter monitors the status of transmission paths and adjusts packet routing accordingly. This feedback loop ensures that when path failures occur, packets are automatically redirected to functional paths, maintaining transmission continuity and utilizing available bandwidth effectively.
