April 7 , 2005 - Podcast #2
We received a lot of great feedback from you last week. Listener Andrew
from STAFFORD. ENGLAND wins the award for being the farthest distance
from Orange County CA. It is very cool to think our Podcast is being
heard so many miles away. We will include more information from Europe
and Canada. But please understand that most of our knowlege and
information is US based. We are not trying to ignore you we just don't
have too much information outside the US. If there is something you
would like us to talk about or if you want to contribute drop us a line
or send us and mp3 comment. We thank you for listening. We will do our
best to incorporate your comments into the show.
This weeks show
On
tap today we will cover the news, talk about where you can get HDTV
programming and how to get it hooked up. We have information about the
HD Summit held recently in Washington DC and finally we give you the
pros and cons of DLP, LCD and Plasma.
How do I get HDTV
There are three basic choices for getting HDTV:
- Cable TV
- DBS (Direct Broadcast Satellite)
- Over the Air (OTA) via an antenna
Cable is the easiest, you just call them and let them hook you up,
you can call your cable system or check their website to see if they
have HD service where you live
Satellite is not much harder to get but
the install is more difficult if you don't currently subscribe. If you
already have sat service it may be as simple as adding a new box. In
some cases an additional dish may be required. Dish Network, Direct TV and Voom all provide HD services. In Canada ExpressVu
is a Satellite provider that has up to 25 HD channels to chose from. I
keep hearing that Voom is going away or is being bought by Dish
network. Voom actually has the most HD channels in the US. They even
have world news in HD. If you go with them make sure you get in with
little or no cost. If you are fortunate enough to live in LA or New
York broadcast area you can get the major networks in HD over the
satellite on DirectTV. Dish Network only has CBS. If you don't live in
NY or LA you can still get the HD feeds if :
- You don't live near a metropolitan area
- You can't get any TV reception whatsoever
- You live more than 70 miles from TV station broadcast towers
Finally you can always ask your local station for a waiver to
receive distant broadcasts. ABC and Fox granted me a waiver and its
great. I record 24, Lost, and Alias from the east coast on my HD Tivo
and watch them early. We'll talk about recording HD in a future podcast.
The last method to receive a HD signal is the old fashioned way by
using an Antenna. You don't even need a special antenna. If there is an
antenna already on your roof just hook it up to your HD tuner and scan
for digital channels. The results are nothing like the old days where
you would see ghosts or snow. If you get the signal strong enough you
are locked on with fantastic picture quality. Over the air is my
preferred way to receive HD programming. It is in the purest form. Both
Cable and Satellite companies will compress the signal for transmission
and then decompress it at the set top box. I live 50 miles from the
transmitters so I have a very large antenna. I have friends that pick
up LA channels with rabbit ears. But they live close to the
transmitters on Mt Wilson. Antennaweb.org
has a great website that allows you to put in your address and it will
tell you what kind of antenna you need to pull in the signals. This
feature only works with US addresses.
HDTV Summit, March 15 2005, Washington D.C.
The Analog Cut-Off, What will it take? What are the opportunities?
Keynote Speakers:
* Rep Joe Barton, R, Texas
* Rep Fred Upton, R, Michigan
* Sen John Ensign, R, Nevada
Goal is to find out when the Analog cut over will be complete.
LCD vs DLP vs Plasma
----
Plasma
----
Pros
* Excellent contrast ratios
* Excellent color reproduction
* Excellent life expectancy
* Excellent viewing angle
* Very bright screens
* Instant picture response
Cons
* Very susceptible to screen burn-in
* Cannot produce deep black levels accurately
* Use a lot of power
* Faily expensive
----
DLP
----
Pros
* Incredible color reproduction
* Lightweight
* Excellent lamp life
* Fully digital displays supporting DVI/HDMI without analogue conversion
* Good price point
Cons
* Requires a minimum of 12-14” depth for lamp-based technology
* Older models (pre-HD2) may not perform as well as upper scale CRT projection systems
* Potential for "Rainbow Effect" in older and single chip systems.
* Bulb replacement can be expensive
----
LCD
----
Pros
* Excellent clarity
* Relatively inexpensive
* Lightweight
* Only 12-16” depth required for RPTVs
* Newer units sporting better contrast levels
* Excellent price point
Cons
* Perceived “screen door” effect common in lower cost front projectors
* Lamp life (2000 hours)
* Color representation may not be the best
* Delayed picture response (blocky-ness or pixelation)
