Thank you for choosing RCA Congratulations on purchasing this RCA High Definition Television (HDTV). Your purchase decision represents an investment in a new generation of technology-HDTV. Even though this is a technologically advanced HDTV, it is the most user-friendly of its kind-with on-screen instructions that guide you through all of the TV's features. The best of both worlds Your HDTV has two tuners: one for regular, analog television and one for off-air digital television (ATSC). On your HDTV's back panel you'll see two inputs-one for cable TV or regular, off-air programming and one for off-air digital television. While you're watching TV, you can switch from one tuner to the other with the ANT•CABLE button on your remote. There are many off-air antennas you can use to receive off-air digital television. Find out which antenna will work best in your environment and where you should put your antenna for the best reception.

What makes HDTV better With your new High-Definition Television, you can embark on the next generation of TV viewing-HDTV. There are many technological advancements that make HDTV better than analog TV, but there are basically three things about HDTV that bring you a superior viewing experience: (1) resolution, (2) aspect ratio, and (3) digital signal and sound. Resolution (it's math...that works for you) The crisp, lifelike picture that people rave about when experiencing true HDTV is due to the resolution this technology provides. The resolution is measured by calculating the number of active lines of pixels. A pixel (which stands for picture element) is a small dot. The picture you see on your TV is composed of these dots. A regular, analog television only has a resolution of about 200,000 pixels (480 vertical pixels x 440 horizontal pixels = 211,200 pixels). The HDTV format is capable of more than 2 million pixels (1,920 x 1,080 = 2,073,600). More pixels equal more detail. In summary, HDTV is capable of resolution that is up to 10 times the resolution of the picture on a regular, analog TV!
