Black borders for non-HDTV video feeds...
 

Hello,

I am using a HDTV tuner in my PC. I wasn't sure if this was normal for
regular TVs with HDTV tuners. With non-HDTV for TV shows, do they also
show black borders on all four sides? If so, then how come tuners/TVs
don't automatically zoom in? I don't mind the top and bottom black bars
due to wide screen format.

Thank you in advance.

It's normal if the station is sending a SD picture in an HD format. In my
area only the NBC and PBS stations send a separate SD channel(s).
On my HDTV Wonder if I change the aspect ratio from auto to 4:3 a SD picture
in an HD format picture will fill my 4:3 monitors screen. An HD picture will
also fill the screen but the ends will be cut off. Which is best depends on
what I'm watching. It's kind of like using zoom.

On my PC or my set top box, I can set the default mode to whatever. I'm
running MythTV on the PC, and the set top box is an RCA ATSC11.
Personally, I have the default turned off in the PC. That way SD broadcast
come in full screen, and HD, and SD over HD broadcast come in as 16:9.
Sometimes I'll zoom SD being broadcast as HD and sometimes I won't.:-)
I've got the RCA hooked up to an analog TV, so I set it to 16:9 zoom I
think for a default on HD channels and regular on SD channels, I think.
Automatic just wouldn't suit everyone I don't believe.

OK, but is it normal to have the black borders. With all that space, you
would think the TV or something would zoom in to fill up. Some how I don't
see that. I don't know if it is the HDTV tuner, the card, or the software.

What software you using? I am using DVB Viewer, but it is quite limited to
this HDTV tuner card. :(

don't know about your situation, and the subject matter is not common to
me, but with the LCD TV/MONITOR I have, the black

border appears with all the formats, varied due to the format opted for,
but are symmetrical.

Since this happens with HD signals carrying SD material, your tv and or
your PC can't know that it's not real 16:9 720p/1080i HD. So there's
no way for them to adjust on the fly.

If I have my program's aspect ratio set to auto the first 4 sub channels on
PBS will fill the screen(in full screen mode) without borders. At night,
watching the HD sub channel only gives me top and bottom borders. Most of
the rest of the stations I get are HD only. Then 4 borders are normal during
say the news, which is always SD in HD. The station is sending the side
borders. Your horizontal borders are probably a different shade of "black"
than the vertical ones. I'd think a computer could detect the black borders
but when the SD picture is blown up it can be kind of ugly. At least it is
on my 1280X1024 monitor and would be worse on a larger screen. If you can
change the aspect ratio settings when watching SD, SD in HD and HD it should
become obvious.

I'm using the same software that I told you I was using about 3 or 4 times
now.:-) MythTV on linux vanilla kernel 2.6.14 with Dvico HDTV5 Gold card.

Ahh, interesting. Are any of you get annoyed by these black borders?
