Default Over the air HDTV: report


"American Insurgent" wrote in message
ups.com...
Many programs are not yet in full HDTV, including
ABC World News. This results in blank space on the sides. Some
commercials are in standard def, which on HDTV makes additional blank
space on the top and bottom, giving an effect of the signal "floating"
on a sea of darkness.


Some channels will NEVER be "HDTV". The system only ALLOWS for HDTV. The
stations have the choice of either a single HDTV channel, OR up to FIVE
lower resolution channels. I can see most network channels running HD only
during prime time or sporting events for the most part, while leaving the
option open to run other services during the day.


Furthermore, the signal was jerky, like streaming internet video, with
frequent pixelation. I even lost the signal for a few seconds, after
which I checked to see if there was a "trip wire" in the settings that
I could turn down or off. I once had a Panasonic TV that would give
you a blue screen if the signal got too low. That I could turn off;
this I can't. If the signal gets too low with the Samsung STB, it will
give you a "weak signal" screensaver.


You will need an outdoor antenna to get a good usable digital signal. Where
rabbit ears, etc. type indoor antennas can normally get a usable (though
often poor) picture, they will not work well for a digital stream.

My setup at first wouldn't pick up several stations with the slew
buttons; I had to download an HDTV channel list off the net, then
manually enter those stations into memory. Even more confusing, the
Samsung box lists channels not by their HDTV assignment, but by their
standard def channel, a hyphen, and a subchannel, ex. 6-1, 6-2, and
6-3 instead of Channel 53. You can USE the HD channel, but it switches
you right back to this hyphenated system on the display. I suppose
this is to ease the transition, and to allow subchannels, but you are
left not only with two channel numbers for one station but something
less than true HDTV, since stations force two or three services onto
one HD channel. I doubt that was the FCC's intention.


Again, it's not HDTV, it's DIGITAL TV, with the OPTION for the station to
use the entire bandwidth for an HDTV signal.

I suspect that when people realize that they're being forced into HDTV-
with beaucoup dollar amounts required to switch-only to get standard
def, they'll be mad. I'm an electronics geek anyway, so for me it was
worth it. But Joe Sixpack will spend this sort of outlay and find his
HD experience reduced so that his local TV station can bring him 24
hour weather or music videos, and start talking a blue streak.



Joe Sixpack most likely doesn't even notice a difference between HD and
Analog (though there is one, most don't notice or care... after working as a
repair tech for decades, I've seen it more than a few times where a customer
would gripe about how their picture looked worse after I changed a CRT... of
course it did.. with the 3/4 dead CRT that was replaced, they couldn't see
the ghosting or the snow.
