If video signals are transported over long electromagnetic pathways using existing media interfaces, then signal transmission distance is extended, but signal quality deteriorates due to degradation
Solution Approach 1:
The video signal is segmented into multiple sub-signals that are distributed across multiple electromagnetic pathways. Each pathway carries a portion of the overall signal, and the pathways work together to reconstruct the complete signal at the destination. This segmentation allows longer transmission distances while maintaining signal quality through diversity and redundancy.
Solution Approach 2:
The invention transitions from single-pathway transmission to multi-pathway transmission, adding a spatial dimension to signal transport. By distributing signals across multiple independent pathways and combining them at the receiver, the system achieves both extended distance and maintained quality through spatial diversity.
2Reliability
If sampled signals are distributed across multiple electromagnetic pathways, then transmission capacity and quality are improved, but system complexity increases due to multiple controllers, distributors, and encoders
Solution Approach 1:
The permutation controllers are designed to perform multiple functions: they manage signal distribution across pathways, handle encoding/decoding operations, and coordinate timing across different clock domains. This multi-functionality reduces the need for separate dedicated components for each task, thereby managing complexity while maintaining transmission quality.
Solution Approach 2:
The system employs dynamic permutation patterns that can be adjusted and optimized based on transmission conditions. The permutation controllers dynamically manage signal routing and encoding parameters, allowing the system to adapt to different scenarios and maintain quality without requiring fixed, overly complex hardware structures.

AI summary
In distributor and assembly bank of a transmitter a predetermined quantity of an input payload from a source is repeatedly written according to a first distributor permutation to create as many input vectors as there are electromagnetic propagation pathways. Into a staging bank each input vector available from the assembly bank are repeatedly written according to a second distributor permutation. A presentation bank exists into which each input vector available from the staging bank are repeatedly written according to a third distributor permutation. One or more encoders repeatedly encode input vectors from the presentation bank; there being as many encoders as electromagnetic propagation pathways; each encoder makes available each encoded series of output levels for communication over the pathways. The banks and encoders are in up to four timing domains. A corresponding receiver, decoder, and reception, staging and disassembly banks and a sink are at the end of the pathways.
