Tech Guy:  I want to clear up some confusion about the whole digital TV transition that's going to happen next year.  A lot of people have said it's an HD TV transition...where does the confusion come in?

Jim Barry:  Well,  it's really both- and there is some confusion.  Digital TV means it uses computer code, and the new format.  The best digital TV is high definition. so all high definition is digital, but not all digital is high definition.

TG:  So some digital cahnnels will be standard definition.

JB:  Standard definition- and you don't really need high definition for some programs.  You certainly need it for your ballgames, with Dolby digital surround sound- for your prime time shows, and for your movies.

TG:  What are the other big beneifts of going digital, other than the better picture?

JB:  Well better picture, better sound we mentioned.  You can also get more programs in one channel- so that's good for both the broadcaster, but it's good for viewers also.  You can get a couple of different programs in the same channel.  Even if you're getting it free off the air using an antenna or using the rabbit ears on the set top.

TG:  For instance, here at ABC 33/40, we do a second broadcast of just weather information.  One big question on my mind...why are we doing this?  Whats the big deal?  We've heard some of the big benefits, but what's the underlying cuase?

JB:  Well, everything is going digital now.  We're using digital cameras instead of film now, we're using digital wireless phones- cell phones are digital. digital- cordless phones around the house.  Digital video discs have replaced video cassettes.  Everything in electronics has gone digital- and depending on the product, you've got real benefits for both the consumers and for the manufacturers and the marketers.
