Adapter for HD

My local tv station will begin to broadcast HD signal soon, and I got an
anolog TV. Do I need to buy some kind of HD adapter/receiver inorder to get
the signal? If I don't buy it, can I still be able to get the signal
through the analog TV? Thanks

If I understand you correctly, the HD signals will be in *addition* to the
regular analog signals. You can keep your old set and everything remains the
same.

However, to receive the extra HD signals, you will need an extra cost
set-top receiver, as well as a TV that can properly display the HD signal.

If/when they are switching from an analog to a *digital* signal, you will
need a *digital*
set-top receiver, but you should be able to keep your old TV.

Not all digital signals are HD...

The analog TV format in use for the last half century is NTSC. You can't
view digital signals on a NTSC only TV without a converter. Note that
existing digital satellite receivers (Direct TV and Dish Network) and
"digital cable" converters are already accomplishing a digital to NTSC
conversion,

The more recent digital format is ATSC with 480, 729 or 1080 vertical
resolutions. These resolutions are typically followed by "i" for
interlaced (like an NTSC signal) or "P" for progressive (like a CRT
computer monitor). Like NTSC TV, interlaced signals generate alternate
lines across the screen and THEN make a second pass to fill in the gaps.
Progressive scans generate each line of the display in order in a single
pass.

Large and mid size televisions manufactured for sale in the US have been
required to have ATSC tuners IF they have NTSC tuners for about a year.
Smaller TVs should be appearing in retailers SOON. "Monitors" often
labeled "HDTV Ready" aren't required to have either ATSC OR NTSC tuners.
TVs and monitors CAN be "digital" Standard Definition (SD) devices
capable of ONLY 480i ATSC display. A TV or monitor should have 720i,
720p OR 1080i capability to have the "HD" label.

Most broadcasters in the US will duplicate their ATSC programming in
NTSC format (downgraded to lower resolution where applicable) for the
remainder of 2007, all of 2008 and the first several weeks of 2009. NTSC
format broadcasting licenses are currently slated by legislation to
expire in February of 2009. This WOULD require passage of legislation in
BOTH houses of the US congress and either presidential approval or veto
override to change. The NTSC cutoff doesn't apply to
converters/receivers used with satellite and cable systems. Cable and
satellite providers are allowed to determine how long they are willing
to support customers with NTSC only TVs. Cable companies will be allowed
(but not required) to continue analog distribution for the convenience
of analog "cable ready" TV owners.

Demand for external ATSC to NTSC converters hasn't been high enough to
support modest priced units Or even widespread availability of expensive
units. The same legislation that set the NTSC cutoff provides for a
government agency to supply up to two $40 vouchers per household to
subsidize the purchase of ATSC to NTSC converters. The agency is
supposed to start issuing vouchers in 2008. I wouldn't recommend relying
on these vouchers if you are using cable or satellite to get your TV
signals. There MAY be means tests to qualify for the vouchers too. The
funds earmarked for the vouchers is nowhere near enough to offer two
vouchers to EVERY household in the US.

Of course any picture you see with an NTSC TV connected to an ATSC to
NTSC converter WILL be displayed in SD (480i).

You will need an ATSC Tuner somewhere connected to your TV. Either in a
PC, VCR, DVD recorder, whatever. You don't need a special TV. You can use
one 20 years old if it still works and has the inputs to match the outputs
of the device with the ATSC tuner(s) in it. You will see exactly what
anyone with a real HDTV will see, only in a lower resolution. It will be a
lot clearer than the NTSC broadcast though overall.

Yep.
Not all digital signals are HD...

ATSC allows for many different formats. The most common are plain SD at a
low signal rate. HD at a high signal rate. And SD over HD.

The advice you got, especially from RobertVA, is excellent. The most
basic thing you need to know is that TV stations will all be changing
over to digital transmission, instead of the analog transmission that
they are using now. When they do that you will need a converter that
will receive the digital signals, allow you to select the station you
want to watch, and convert it to a signal your TV can understand.

You'll also want to know that HD stations broadcast digitally, but
digital transmissions don't have to be HD. They can be Standard
Definition. The difference is that SD fills your current TV, and HD
fills (usually) the newer wide screen TV's.

=============================
You understand incorrectly.
ALL analog will be shut off in 2 years.
ALL transmissions will then be digital.
This will include SD DTV and HDTV.

It sounds like you understand some of it, but why does the last half
contradict the
errors in the first half of you post?

Not true--I will be watching Fox in analog past 2009 because the
network affiliate here is low-powered and doesn't even have a digital
freq assigned yet.

I'm not happy about it but it is what it is. I wasn't aware of it
until Alan F. posted about it awhile back. Certain low-powered
stations are exempt.
