Comcast's STB's tuner tunes sub-channel type channels (like

No STB I've seen has a "-" or "." in their channels. They
are channel
1-999 as whole numbers. What is the model number of the box
that has
"-" symbols in its channel numbers?

I guess I should simplify.

To watch ESPN, you tune your STB to channel ____.
To watch ESPN2, you tune your STB to channel ____.

Your zip code is _____.

You "tune" the STB to 49, BUT the box has been trained by
Comcast to know that in my area (E. MA) ESPN is actually on
QAM frequency/channel 75.9.

And you know that the box is tuned to 529.31 MHz (channel 75's
QAM carrier)
how? How do you know that the box isn't tuned to 375 MHz
(channel 49's
carrier) ? If you use a TV directly, you tune to 49 (375 MHz),
right?


I don't know how Rick knows, but I know how I know. We've two
TWC DVRs and two PC based tuners. The PC based tuners find the
actual, PSIPless channel and stream used by the cableco, so it's
quite simple, in our case, to know exactly where unencrypted
shows are on cable, regardless of what their box says. Example:
STB 402=CBSHD, 404=NBCHD, 405=CWHD; OnAir 82.1=NBCHD,
82.2=CBSHD, 82.3=CWHD. Cable channels 119, 124, 128, 134 and
135 are also used to carry unencrypyed HDTV streams which all
show up on the STBs in the 4xx range. Unlike Rick, none of the
digital channels appears on the STB below 100. There are
several unencrypted SD streams below 100 found by the PC tuners
as well as a few encrypted streams which we can not view. There
are still about 60 analog channels supplied by TWC here.

I made up my own spread sheet with those correlations.

I'm not at all interested in how *you* know. *You* didn't make
the comment that you received ESPN & ESPN2 in Clear QAM.

I still want to know what makes you think ESPN on channel 49
is Clear QAM.

Clear ::= unencrypted

QAM ::= cable modulation in digital format

I see and believe!-)

You really *don't* understand, do you? Channel 49 on your TV is a
6 MHz wide NTSC analog channel, not even a digital channel. NTSC
video uses AM (amplitude modulation), and its audio uses FM (frequency
modulation.) Only the color sub-carrier uses QAM, and it's analog QAM.

Digital QAM channels have a xx.x or xx-x format on a TV.
Analog channels have whole number channel numbers, with no "." or "-".

I am afraid it's you that doesn't really understand. Any broadcast of any
type can be on any channel number assigned to it. All I get is OTA ATSC
and I don't use any delimiter in the number. For instance if I want to
switch to the first sub-channel of any station I enter just the station
number plus the sub-channel. In my case, 49 would be the same as 4.9 or
4-9 in your world. Now the reason for this is the software I use allows
me to do that. And while I've never had cable or sat TV, I'd certainly
assume that they have the same, if not more, capability to assign channel
numbers any way they want to. It is their system after all, and they
control all the channel numbers and frequencies. So it would be easy for
them to assign a QAM HD broadcast to channel number 49, 499, whatever.
Now if it's clear qam, the TV should pick it up on a scan. I find it odd
that they use 49 for an HD broadcast, but they can do it.

We're talking cable hyperband here. Channel 49 is a 6MHz wide NTSC channel
with the video carrier at 373.25MHz and the audio carrier at 377.75MHz. If
a tuner in a cable ready TV tunes to 49, it tunes to an NTSC analog channel,
period. How you have your remote/tuner set up for OTA is quite irrelevant.
ESPN viewed on channel 49 on a TV is NOT Clear QAM...period.
