Gee, when I talk to real broadcast engineers from LA stations -- including
those working at owned and operated ones, they tell me of how little their
plants have changed at this point to accomodate digital. If NBC has a 601
plant (designed to take advantage of the full capabilities of digital), then
they are the only one. There are plans, sure.
And, KABC can send wonderful live shots from their HDTV Helicopter, the second
in the nation (KUSA Denver being the first). Last time I checked, not a
single station in the market had bought HDTV cameras, and there was only one
HDTV ICR/TVPU microwave link in use in the city.
When was the last time I checked? Abpoit 10 weeks ago.
What do you know that I don't Tony? Or, are you saying more than you know to
be true?

In Las Vegas the stations are selling off some of their ATSC bandwidth to
USDigital. That would account for the SD pix being poorer than the NTSC. This
is a special case. Not the fault of the design specs of the system. I never
meant that Digital transmission could overcome downgraded transmission or poor
reception.
I have gone to the trouble to install a good antenna, on a mast 10 feet above
my roof and I get very solid digital reception, as well as excellent NTSC
reception. Even on my 42" HDTV plasma the standard definition programs look
much better than via the NTSC transmissions. This is partly due to most Los
Angeles stations haveing gone to great length to upgrade their plants to
accomodate the full capabilities of digital.
The system is capable of providing much higher quality pictures than analog,
even when viewed on an analog set. As far as the reception problems go,
tests here in Los Angeles have shown more locations get better reception on DTT
than worse. Terrain features here have meant that many homes were never able
to get NTSC signals either. Also those homes in the shadows of huge oil
refinery or container crane structures will never get any decent OTA reception.
My experience has shown that any change to improve service will result in some
locations getting poorer reception. This occurred when we went to circular
polarization. Surveys of TV repair shops got overwhelming reports of improved
reception, but there were numerous homes that had worse.
Cable isn't perfect either. Los Ageles City has gotten so overwhelmed with
complaints about poor cable service that the city council is undertaking an
overhaul of all the cable franchise terms and regulations. I'd bet that it
will prove un-neseccary as competition from satellite spurs the cable companies
to improve greatly.

Tony
