When you get up into the higher number of subchannels, you're talking about splitting the bandwidth 6 ways, 7 ways, or more. Each channel gets less and less, ultimately causing signal degradation on the main channel as well. You may have perfect signal strength, but due to the bandwidth split, pixelization will still occur".
I'm not saying I know. I have a little outdated knowledge because I worked in satellite and OTA transmission/ reception but it was 20+ years ago. Lot's has changed since then. But if TVvoiceguy is right and OTA bandwidth is already being loaded up then I would question whether OTA frequencies have enough bandwidth to have the existing data and have the added data required for scrambling/descrambling.
