 RB>>> PAL is the TV system, like NTSC in the States.

 RW>> NTSC is no more.

 RB> Really? So how many millions of older TVs have been junked?

Who knows? Many people have replaced them with HDTVs, while those who
can't afford to, have an opportunity to buy a subsidized converter box, if
they're lucky enough to get the discount coupon before they run out. That
cost is minimal with the coupon, about $60 without one.

The DTV receivers put out an analog signal, which those older TVs can
use. It utilizes right and left audio and one video output for more modern
analog TVs (VCRs too) and an RF out for those that don't have the RLV
input jacks...

 RW>> Yes, but the system also enhances it to digital mode.

 RB> "The system"? An NTSC TV runs NTSC, period.

Doesn't matter, the video is enhanced. Putting a switch box between
antenna input and DTV box input and you'll be able to see a slight
improvement over the standard analog picture from the antenna. Of course,
when the analog transmitters go off the air, this is a mute point.

A DTV signal received over the air doesn't have anything to do with an
HDMI in/output, rather the old RCA RF connector or RLV is used.

Even on my HDTV. It has six selectable inputs. Each input can use RGB,
S-Video or RLV, while only two can use HDMI and/or RF.

Of course, there was nothing else available at the time. I don't see those
giant 10' dish antennas anymore either, which means those sats are
probably not there anymore.

 RB> They turned off analog broadcasting from the satellites here several

No new LNB is required here. They just replace the indoor receiver with a
DTV output and that's it.

 RW>>>> GSM is also used in the US...That's why it's real name is Global
 RW>>>> System for Mobile communications.

 RB>>> Also used, yes. Exclusively used, no, in contrast to Europe.

 RW>> More exclusively than not.

 RB> Ever hear the expression "that's like being a 'little' pregnant"?

Yes, a little pregnant would be first trimester when the bulge in the
belly isn't there yet. It's also easy to be 'not pregnant' in that stage.

 RB> But I agree that the GSM system appears to dominate in the States as
 RB> well as here.

Just got back from the doc's office. Her nurse is pregnant and she looks
like she's going to pop any minute now. She said she had two weeks to
go, but I don't think she'll last that long. I'll find out next month when
I go back.
