We've already established that DTV means a crisper, perfect picture. It also gives broadcasters the ability to deliver much, much more to enrich your TV viewing experience.
TV will sound better. With digital TV, you can get six channels of CD-quality Dolby Digital Surround Sound. Owners of home entertainment systems will recognize the six channels: Center speaker, right and left front speakers, right and left rear speakers, and one channel for the subwoofer (technically, this is referred to as 5.1 channels, with the subwoofer being the ".1" channel).
By attaching your DTV receiver to a Surround Sound speaker system, you'll hear the train chugging from left to right, you'll hear the plane coming toward you and then behind you, you'll hear the birds chirping around the scenery.
And that's not all!
When we're not broadcasting an HDTV program that has five, six, even ten times the clarity of today's TV, there's enough room in digital signal to broadcast four TV programs with today's picture quality. They would appear on your TV as channel 2-1, 2-2, 2-3, and 2-4.
WBAY, for example, broadcasts three TV signals: Its primary channel, which includes WBAY's regular programming including ABC primetime and Action 2 News; StormCenter 2 24/7, which is an always-on weather channel with current conditions and forecast information; and the Retro Television Network, bringing back popular TV shows from decades ago.
But wait, there's more!
You could someday see a channel of information devoted to the program you're watching. Imagine not having to sit through the credits at the end of a TV program or movie, because ABC made the cast list available during the show complete with a list of their previous work on a separate channel. When one TV show ends the next one begins with nary an interruption.
During a football game, see the team rosters on another channel and read the season and career records for the wide receiver the announcers are talking about.
Turn to another channel during Action 2 News at Noon to see the schedule for that Weidner Center production they're talking about and the phone number for ordering tickets.
Digital TV isn't only changing the way you watch TV, it will someday change the way we produce and broadcast it.
