What Channels Am I Seeing?

I have Comcast Digital Cable that is hooked up to an old CRT rear-projection
TV through a set top box. It works fine.

My other old CRT TV was just hooked directly to the cable-- no box and it
was fine too--- until it died last week. I replaced it with a nice 42"
Panasonic plasma that I've temporarily just hooked up to the cable. I get
all my regular channels-- but also repeats of them at higher channel
numbers-- some hyphenated as in 81-201 or 11-1. I assume that these are
digital or HD versions as they give a much better picture.

So what are these?

And I'm assuming I'll need to upgrade to the HD package from Comcast...

Yes they are digital channels. You may be able to get some of these without
a box (below a certain channel number), but to get all of them you will need
a box from Comcast.

You can also get local stations broadcasting in digital (most of which are
HD) using a regular antennae if you live close enough the broadcast tower.

You are likely seeing the local channels in hd.
They are qam channels, as opposed to atsc. Most
qam channels are scrambled, but not the locals.
