This will be a greater leap in the quality of the home entertainment
experience than even the change from black-and-white TV to color, or
Hi-Fi to Stereo, or AM to FM. HDTV, in addition to picture and sound
will also deliver data services, such as electronic program guides or
information related to the programs you watch. Local broadcast stations
broadcasting in HD will be able to broadcast one extra high quality
picture, or several separate camera angles equal to today's pictures.
HDTV will offer the opportunity to develop sophisticated services that
meet consumer demand for flexibility and convenience.
HD will be
presented in a 16:9 format and will allow resolutions up to 1940x1080
plus provide you with twice the amount of picture information both
vertically and horizontally. It will not work on regular analog
televisions since these sets don't support the interfaces required for
HDTV signals.
After February 17th of 2009 local analog TV channels
will stop transmitting, everything else connected to your analog TV will
continue to work.
DVD
By the time HDTV is wide spread,
high-definition movies will be on the shelves, playable on Blu-ray, HD
DVD or both, depending on which way the format wars go. When you switch
over to HD, you may need to connect your HD set-top box, Blu-ray or HD
DVD player to your TV using a HDMI (High-Definition Multimedia
Interface) cable. Both Blu-ray and HD DVD are compatible with existing
standard DVD, so you can play your current discs on a next-gen player,
but the two competing formats are not compatible with each other. It's a
bit of a laugh if you are old enough to remember the 'Beta-Max VHS
Wars', Beta you say?
Technology
What problems are facing
the early adopters of this new technology and what caveats remain for it
to become mainstream? The people buying HDTV units today are known as
"early adopters". They usually buy whatever is the 'Latest &
Greatest' especially in the Hi-Tech field. Other consumers will have to
be sold on the technology. A huge number of older television sets will
instantly become obsolete and when their owners make plans to replace
them, newer technology like HDTV as it exists at the time of the mass
conversion will be very attractive. You can bet that there will be a
market for 'conversion hardware' to enable the use of 'analog' sets with
the new HD Broadcast Technology. If you now record off-air local TV
shows on your VCR you will not be able to continue doing that after
February 17th of 2009 without an upgrade. To continue recording local TV
programs you will either have to connect a Digital to Analog TV
Converter box to your VCR or purchase a different TV recording device
that has a DTV tuner built in. You'll need that to continue to record
programs from local TV stations after February 17th of 2009. The advent
of Tivo will eventually make the VCR question irrelevant.
While
the prices of HDTV sets are dropping, the High Definition equivalents of
many of the complimentary technologies that we've come to expect will
remain relatively expensive, such as home recording and storage media.
The HD DVD and Blu-ray war is another slow down in bringing High
Definition technology into the mainstream. In reality the main
distinctions between competing HD formats will be virtually unnoticeable
unless you are viewing on a screen 55"+ in size.
Antenna
In
cities across the nation stations have already begun broadcasting an
HDTV signal, receivable with an antenna. In order to receive
over-the-air digital and HD signals, you need a tuner and a digital
antenna. In order to watch local network affiliates, some satellite
customers may have to switch from their dish to an antenna. To receive
HDTV via antenna you'll need: An HDTV, HDTV tuner, HDTV antenna.
Depending on your location you may need an antenna rotor to point the
antenna to multiple broadcast towers.
A major hurdle to overcome
with over-the-air HD broadcasts via Antenna is, the technology has to
overcome the 'consumers' mis perceptions and long held myths, combined
with lack of knowledge about the capabilities of antennas. The solution
to the Antenna/Satellite conversion question may have a more long term
effect on the consumer response than the seemingly obvious debate in
other hardware.
Note: HDTV tuners that come built-into many HDTVs are
over-the-air tuners for use with an antenna and cannot be used as your
cable HD tuner.
Local Response
It's always a good idea to
check with your local TV dealer regarding what HDTV services are
available in your area before buying. It would even be a good idea to
call your local TV stations and ask for the Chief Engineer to find out
the stations' particulars.
