Introduction Thank you for choosing RCA Congratulations on your purchase of an RCA High Definition television-a true viewing experience. Your purchase decision represents an investment in a new generation of technology. High Definition: What Makes it a True Viewing Experience You have chosen to embark on the next generation of TV viewing- HDTV. There are many technological advancements that make HDTV better, one of the largest aspects that bring you a superior viewing experience is resolution. Resolution The crisp, lifelike picture 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 television (called standard definition or analog) 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. And more pixels mean greater detail. So HDTV is capable of resolution that is up to almost 10 times the resolution of the picture on a regular, analog TV. Integrated HDTV Tuner with QAM RCA was the first to offer an integrated tuner with its HDTVs (no need for another box to receive digital programming). Now, we've gone one better- your HDTV's tuner is ready for digital cable (no need for a cablebox to view unscrambled digital cable programming). The tuner is able to decode all 16 formats of digital television broadcasts and it can interpret digital cable signals because it includes QAM (Quadrature Amplitude Modulation). Note: A cable box may be necessary to view scrambled channels. Contact your cable providerfor more information. 2
