Another very basic question...

Another very basic question...

[r bartlett]

I'm happily watching the several QAM channels available on my line...but can I also watch the 80 some channels that my television gets?  Is that "NTSC_M"?

Right now, if I turn on the TV I can get History, Food, Cartoon Network, etc...but on the computer it's only the basic networks and PBS.

Am I still doing something wrong?

the question is moreover what device do you have in your computer?
Also another question is are those NTSC-M Channels analogue signals
(so is it possible to connect your cable directly to an old
television, or do you have a receiver in between).
There are hybrid ATSC/QAM devices available which can also handle NTSC-M.

Re: Another very basic question...

[r bartlett]

I've got a WinTV-HVR-1800, which has an analog tuner and a ATSC/QAM tuner.  The analog side seems to not yet be supported (It works -- I can boot to Vista and watch the analog side) by Linux, but I was wondering whether I can tweak my channels.conf or something and get more digital channels.

I'm kind of new to the various ATSC, QAM, NTSC_M stuff.  My assumption up to this point has been that if I want to watch the full range of channels (1-120) or something, I need to do it through analog.

My system is Comcast Digital cable with OnDemand, a Comcast-supplied box (looks small, like a router, not a PVR) and remote control (neither of which I'm currently using), and a Y-split cable line that goes directly to my tv card.  Currently I'm seeing things like NBC, CBS, ABC, PBS (a few channels), FOX, CW...and a few local stations.  If it's also possible to tune to Food Network, Sci-fi, Cartoon Network, etc, that would be great.  These stations come in fine on my regular television with no box or anything -- just the cable line going into the house.  I'm guessing that if more channels were _going_ to come in at all on my tuner card, they'd already be coming in.  :-)  But I could be wrong.

>From reading other posts and following a few other forums, it looks like the analog part is still not supported by the 2.6.24 kernel.  But if these other channels are available on the digital side, that'd be cool.  My tuning, thus far, has only been on QAM256.  ATSC (antenna, right?) didn't come in at all.  I haven't tried HRC or the others. Just us-Cable-Standard-center-frequencies-QAM256, which found about 350 signals, of which only about 10 were actual working channels.

Is it possible to have more channels come in?  Should I plug in my Comcast box and use a different method to scan for channels?  (I've tried plugging in the box but that seems to kill my digital signal entirely -- I then don't get any channels)

Thanks for putting up with these really basic questions.  I apologize in advance...and greatly appreciate the help!

[CityK]

I'm going to be blunt about something -- you're not being particularly 
helpful to yourself or the list:
- To yourself because you're not being very efficient.
- To the list because you're breeching etiquette.

Here are a few tips:

1 - instead of breaking threading, and opposed to having a zillion 
different threads essentially all about the same things, keep your 
content within one i.e. the original message ... having a contiguous 
thread will also help those who may, in future, search the lists for 
similar problems

2 - entitle your threads appropriately  -- i.e. "another very basic 
question ... " or "the final inch" are not very helpful  .... the last 
one in particular, given the thousand or so emails I receive each week 
from China, Russia etc etc regarding viagra, penis enlargement etc etc 
etc ... if your goal is to get/reach those who are most capable of 
helping you, you're certainly going about it the wrong way ... (i) busy 
people will browse over items that don't seem interesting or appear on 
the surface to possibly be spam  and (ii) please don't ambiguious 
messages  as it just ends up wasting others time in trying to figure out 
what your question is/relates too (i.e. perfect example: Merc trying to 
figure out what you were talking about in this thread)

3 - a number of the "basic questions" you have posed are readily 
answered in the wikis ... so, in posting here about these elementary 
issues,  you've wasted your and my (and others) time too ...
- your time because you likely could have read about the solutions 
quicker then you typed/enquired about them
- my and others time because we've already spent considerable time 
trying to document such elementary questions in the wiki ... and my time 
again in having to compose this message to draw light to this fact

4 - please don't top post

That's correct, analog is currently not supported under Linux ... except 
for preliminary/experimental support available in one of stoth's Hg repos

The Food network etc channels you are seeing on your tv (cable straight 
from wall to tv) are analog channels.  As your tv card currently doesn't 
support analog, these won't work.  If your cable co. transmits 
unencrypted digital versions of those channels, your card would work.  
Doesn't sound like that is the case for you....In other words, there are 
no "tweaks" for your channels.conf file that are going to acquire those 
channels.

> ATSC (antenna, right?) didn't come in at all.  

Yes, ATSC is digital over/off-the-air and requires an antenna for 
reception .... it uses 8VSB modulation.

Digital cable in North America (which isn't ATSC, but is highly 
conformative and interoperative with ATSC, and where the remaining 
differences being defined by SCTE etc standards)  typically/by defacto 
uses QAM (Quadrature Amplitude Modulation).

Certainly sounds like your cable operator/supplier uses centre frequencies

> Is it possible to have more channels come in?  

Only if they are unencrypted.

Doesn't work that way.  Can't remember if I wrote about it in the wiki 
or not, but I do have a bookmark handy;  See:
http://archive2.avsforum.com/avs-vb/showthread.php?p=7328646&&#post7328646

The post is a bit dated now, and in reference to something else, but it 
should contain an explanation regarding why  
STB_RF_output--to--digital_tuner_card_RF_input doesn't work.

NP -- but please do heed the advice in the previous message.
