I have a question:
what is the best value for LDPC?
and more over: if the LDPC value is bad who is the culprit? the transmitted signal that might be "distorted" or the receiving system?

Hi,
about it I observed that after 45% of error correction, image and audio start to experience serius issues, after 50 % the signal is loss.
Anyway with a high percentage of error, the systems has more work to rebuild the original frame.
Under 30 % I haven't observed problems to decode correctly signals, sometimes you may have a glitch, but after the image and audio return to a good quality.
Regards.
Please see this very intreresting video that simply explain the Low Density parity Check :
I have been transmitted it on QO-100 WB trasponder several times.
Hope this is useful for you.
Regards.
