heres some of what DTV had said in reply when I asked them about it :
Dear Tony,
Thanks for asking about High Definition Television (HDTV). DIRECTV was
the first national broadcast service to offer HDTV programming, and
we're proud to offer you an unbeatable selection of programming
featuring this exciting technology. For the channels we carry in HDTV
format, DIRECTV provides a turn-around service. This means we receive
and transmit the content without decompressing and compressing content,
so the resolution provided to the customer is exactly the same as the
resolution transmitted to DIRECTV by the program providers.
Our newest package for customers with HDTV equipment delivers the most
popular channels available, including ESPN HD, Discovery HD Theater,
HDNet and HDNet Movies, as well select NFL Network programs. Additional
premium HD channels are available with subscriptions to the premium
package that contains them: HBO HD is included in the HBO package;
Showtime HD is included in Showtime package; and select NFL SUNDAY
TICKET games (subject to blackout and game availability restrictions)
are available with a subscription to NFL SUNDAY TICKET. We also offer HD
pay per view movies, and sometimes free NBA games (blackout restrictions
apply) on channel 85. Visit DIRECTV.com/HDTV to read all about our HDTV
service and the equipment you need to receive those channels.
We also recently began offering CBS-HD to customers in selected areas of
the country where we have permission from the local broadcasters, and we
hope to have an agreement with FOX to offer their HDTV broadcasts soon.
Visit DIRECTV.com/HDChannels to see if CBS-HD is available in your area.
In addition, most high-definition DIRECTV receivers allow you to get
your high-definition broadcasts from your local networks by using an
off-air (rooftop) antenna in combination with your HDTV equipment. If
you have this setup, your local channels appear on the DIRECTV on-screen
guide for easy selection. For more information on how to get HDTV
broadcasts using an off-air antenna, check with your local HDTV
retailer.
We are committed to continue providing the best in HDTV programming and
we're in constant discussions with various program providers to increase
the number of high definition programs we offer. Stay tuned to
DIRECTV.com/HDTV for the latest news and announcements as they become
available.
Sincerely,
Ed
DIRECTV Customer Service
