All of the subchannels are combined on just one transmitted channel. If all the other subchannels are OK, but 27-2 isn't OK, then the problem is not with the transmitter, it's with the network content feed from VIDORTV.I have been playing around with the 27-2 channel, and today they are showing 55-58% quality, although there is not any Video or audio.
The other 27-xx channels are all showing the same quality, along with normal video and audio. Do they have a sub-carriers on these
digital channels for a marker?? I'm beginning to understand that I don't understand all this HD-digital transmission particulars.
