Introduction
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 be-
cause 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.
Other Key Features of owning an RCA HDTV
There are other HDTVs on the market. But your RCA 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.
TruScan Digital Reality™ Feature
With the Film Mode option turned on, the intelligent signal processing of Film Mode Film Mode
the TruScan Digital Reality feature 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.
DVI-HDTV Input
Lets you connect a component with a DVI (Digital Visual Interface) output. DVI
provides an uncompressed, digital video interface developed for high-bandwidth
digital connection. It supports the overlay of high-resolution graphics needed
by some electronic program guide navigation and other interactive services.
DVI, when combined with HDCP (High bandwidth Digital Content Protection)
technology, creates a protected digital connection. The DVI-HDTV connection
is designed to display either progressive scan (480p or 720p) or HDTV (1080i)
signals at a bandwidth of up to 1.78 Gigabits per second.
