Will Directv HDTV Be Revolutionary?
Author: James Croydon

When we speak of transmission of pure digital television, we
mainly talk about its reception and display of the signals.
These signals come to us through the broadcasting over air or
by transmission through the satellite system or cable system in
our houses. There is a class of Direct TV that is getting a lot
of name at present which is called DirecTV HDTV. When we
combine a digital TV of high resolution with a Dolby surround
sound (AC-3), we get a DirecTV HDTV. To have a stunning image,
this combination has been made.

A new production and transmission equipment at the DirecTV HDTV
station and even a new equipment for reception for DirecTV HDTV
is required by the consumer. The strongest selling point for
DirecTV HDTV is the higher resolution picture. After media's
perfect show up about DirecTV HDTV, the DirecTV HDTV has
reached to all the electronic stores. The higher resolution
which produces crystal clarity, as never seen before through
picture tube, gives us a life like picture and digital sound. A
usual TV gives us an effective picture resolution of about
210,000 pixels whereas in the highest resolution DirecTV HDTV
format, each picture contains 2 million pixels. This nearly
gives us ten times more detailed picture. The basic aim behind
DirecTV HDTV is not to increase the definition per unit area
but it is rather that the visual field percentage contained by
the image should be increased. The proposal about all DirecTV
HDTV was first submitted by General Instrument Corporation on
May 31, 1990

By December 1990 ATRC also launched the same followed by Zenith
and AT&T and the MIT. At present Japan is the only country which
broadcasts DirecTV HDTV services to the viewers. The number of
converters and receivers sold to the customers has reached to
100,000 and 30,000 respectively. The possibility of starting a
digital satellite HDTV service in Japan has been eliminated by
the establishment of the analog broadcast service, DirecTV
HDTV. Right now, many stations do not broadcast HDTV program.

Slowly, the current analog TV can be either replaced or a new
set-top box can be purchased for converting the digital signal.
While purchasing any TV receivers we should first ensure that
the new receiver has all the input jacks that match the
connectors on the VCR, cable boxed DVD player etc.

We should always go in for a composite, S-video and component
video as a minimum set of analog jacks so we can use our
existing analog equipment with a new set.
