Digital Signal and Sound
The analog television broadcast system that has been used in the United States for the past 50
years transmits signals as electronic waves. These waves can suffer degradation as the signal
travels to your home. Additionally, the analog waves are susceptible to interference from planes
passing overhead, weather, and household appliances.
Digital signals, in contrast to analog signals, can be reproduced precisely because the images
are transmitted and received using the computer language of 1s and 0s. Such precision yields a
signal that is capable of displaying studio-quality picture and Dolby Digital 5.1 channel sound.
Part 3: Other Key Features of owning an RCA Scenium HDTV
There are other HDTV’s on the market– even some that use DLP™ technology. But your RCA
Scenium HDTV has been designed with features that will enhance your TV viewing experience,
and features that provide fl exibility to build on the digital revolution that is taking place. A
summary of your TV’s most unique features follows. Go to Chapter 3 for more details on these
and additional features.
Integrated HDTV Tuner with Digital Cable Ready QAM
RCA Scenium was the fi rst to offer an integrated tuner with its HDTVs, which means there is no
need for another box to receive digital programming. Now, we’ve gone one better–your HDTV’s
tuner is digital cable ready, which means there is no need for a cable box to view unscrambled
digital cable programming. The CableCARD™ slot on your HDTV allows you to use a digital
cable card to access digital cable. The tuner is able to decode all 35 formats of digital television
broadcasts, and it can interpret unscrambled digital cable signals because it includes QAM
(Quadrature Amplitude Modulation).
Note: A digital cable card may be necessary to view scrambled (encrypted) channels.

TruScan Digital Reality
The intelligent signal processing of TruScan Digital Reality recognizes incoming video signals
and progressively converts them to achieve optimum digital picture performance. It also
recognizes when original fi lm sources have been modifi ed and can automatically convert
the analog frame rate back to its original format to bring out the detail–a process commonly
referred to as reverse 3:2 pulldown.
