About High Definition Television
High Definition TV will dazzle you with up to six times the picture detail of
conventional TV. HDTV means a widescreen 16:9 picture with cinematic sweep and
grandeur. It also means Dolby Digital sound, including surround sound for movies and
TV dramas. Best of all, High Definition television is not a promise for the future. It's
here today. The DIRECTV satellite service carries three HDTV feeds (HBO, Showtime
and HDNet) to a national audience. Some cable TV services are beginning to offer High
Definition feeds. And HDTV is becoming more and more available in over-the-air TV
broadcasting.
In May 2003, the National Association of Broadcasters (NAB) reported that 885
television stations in 189 cities are broadcasting digital signals that can be received in
97% of American homes. More than 78% of homes are in markets with five or more
digital television broadcasters. And many of these digital broadcasts are in High
Definition.
An April 2003 NAB listing of shows broadcast in High Definition includes 8
Simple Rules for Dating My Teenage Daughter, Alias, American Dreams, Crossing
Jordan, Becker, CSI: Crime Scene Investigation, CSI: Miami, The Drew Carey Show,
Everybody Loves Raymond, Frasier, Hack, JAG, The King of Queens, NYPD Blue, The
Practice, Reba, Robbery Homicide Division, Smallville, The Tonight Show with Jay
Leno and Without a Trace, plus 40 other network TV shows.
This doesn't even count HDTV sports and special events, which have included
NCAA football, the Rose Parade, the Super Bowl, the U.S. Masters Golf Tournament, the
U.S. Open Tennis Championships, and the 2002 Winter Olympics. In addition, ABC has
announced that it will transmit the NBA finals and the Stanley Cup, as well as the 2003-
2004 season of Monday Night Football in HDTV.
For many viewers, one stumbling block on the road to HDTV has been the
relative lack of local HDTV broadcasts over cable TV. But recent agreements between
representatives of the consumer electronics industry and the cable television industry
have done much to clear the way to widespread distribution of local HDTV broadcasts
over cable.
The U.S. recommendations for Digital Television (DTV) broadcasting actually
encompass 18 different television formats. High Definition TVs and HDTV set top
boxes (usually called "HDTV receivers") are designed to tune all 18 formats. Six of
these are designated as "High Definition," while the others are called "Standard
Definition." All but a few formats can deliver a visibly better picture than conventional
television. Broadcasters have been encouraged, but not required to use their DTV
spectrum for High Definition.
