Digital Signal and Sound
Th{' analog t{,levision broadcast system that has be_'n us{'d in the' United Statc,s
for the past 50 years transmits signals as electronic waves. These waves can
suff_T degradation as the signal travels to your home. Additionally, the analog
waves are susceptible to interf{'rence from planes passing overhead, weather,
and household appliances.
l)igital signals, in contrast to analog signals, can be reproduced precisely be-
cause the images a,'e transmitted and received using the computer language of
ls and 0s. Such precision yields a signal that is capable of displaying studio-
quality picture and 1)olby Digital 5.i channel sound.

TruScan Digital Reality TM Feature
With th(' f_i/l_ MoclP option turned on, th(' intellig{,nt signal proc'{'ssing o["
the TruScan I)igital Reality f_,ature recognizes incoming video signals and
progressively converts them to achieve optimum digital picture performance.
It also recognizes when original film sources have been modified and can
automatically convert the analog frame rate back to its original format to bring
out the detail--a process commonly ref{,rred to as reverse 3:2 pulldown.
DVI-HDTV Input
L{'ts you conn{'ct a c'omponent with a DVI (l)igital Visual Int{,rfac{,) output. 1)VI
providos an uncompr{,ss{,d, digital vid{'o int{,rtac{, d{,v{,lop{'d for high-bandwidth
digital connection. It supports the overlay of high-resolution graphics needed
by some electronic program guide navigation and other interactive services.
I)VI, when combined with H1)CP (High bandwidth Digital Content P,otection)
technology, c_{'ates a protected digital connection. The 1)VI-HI)T\/ connection
is designed to display either prog,{,ssive scan (480p or 720p) or HI)T\/ (1080i)
signals at a bandwidth of up to 1.78 Gigabits per second.
