Interesting. I think my only issue would be with the clarity of the patent. I admit to not being skilled in the art of broadcast video but not completely ignorant of video compression ideas either. Still, the "legalized" writing style makes for very difficult reading. Did you have a working version before applying for the patent?
We didn't build a functioning sample but I'm not sure what the point would be. The implementation you would build for a real deployment would depend massively on the constraints of the system you were working in (what enhancement, existing encoding, receiver hardware capability - decoders, storage, mixing, bandwidth and latency of supplementary channel).
