"O.k, High Definition TV broadcasting. Television stations in your local broadcasting area can broadcast a High Definition video signal over the air which means you would need an antenna to pick these signals up, either attached to your TV or on the top of your house. The broadcasting signal differs from a Standard Definition Television signal because it's completely digital. You must have a special tuner for this reception either built into your TV or separate, as a separate digital receiving device. And, then you would be able to get the High Definition image being produced onto your Television set.

It'll take up the entire wide screen of your television set, as opposed to a standard broadcasting which will have bars on the side of the screen and that creates a standard four by three television picture."
