Yes, I know that, further I actually understand how it works, including the math behind QAM and NTSC-VSB (the old Analog TV system) and many other communication systems.
What I was asking is his park has a block decoder. That is rather then just translating one QAM "channel" to send to the TV (like the converters those parks have to provide) a block decoder is programed to translate various QAM channels into analog channels
Of course they have to pick and chose which channels get translated and which get left behind.
The entire point in digital TV, be it QAM (cable) or ATSC (broadcast) is that you can get more "channels" then one in a "channel", so when you block translate, you only get something like 1/3 or 1/4 of the channels, and none of then HD
