Scrolling Index
Three new features will be discussed in this section:
•Scrolling Index
•DVI Interface
•Memory Stick® Interface
ScrollingIndex
The Scrolling Index allows you to select your
main video from a scrolling index of video
pictures.
TheScrollingIndexappearswiththecurrently
selected program in the main (left) window
and four scrolling video pictures in windows
down the right side of the picture tube.
As each picture on the right scrolls to the live
preview window, it changes briefly from a
frozen video to live video. The right side
continues to scroll through the entire channel
list.
Factors Affecting the Scrolling Index:
ØScrolling Index does not function
if you use a cable box to view all
channels.
ØSources connected to the AUX,
Video 5, Video 6 and Video 7 inputs
are visible in the left window, but not in the scrolling right windows.
ØScrolling Index does not function if the parental controls are set.

Introduction
As the digital display technology (e.g. Plasma and LCD) grows so does the need to replace the present analog
HD component connection between external digital device (e.g. Digital TV/Satellite Receiver) and the HDTVTM
set. The issue is the inherent picture quality problems caused by Digital-to Analog (D/A) and Analog-to-Digital
(A/D)conversionprocesses.
For example, if you have a digital Plasma display HDTVTM and a Digital TV/Satellite Receiver, the digital video
signal in the Digital TV/Satellite Receiver must be converted to a analog component video signal and then sent
to the HDTVTM where it must be converted back to a digital signal video to drive the Plasma display. Because of
the two video signals conversion steps and the possible analog signal loss across the connection between the
HDTVTM and the Digital TV/Satellite Receiver, the picture quality will suffer. Even with an analog CRT the Digital
TV/Satellite Receiver video signal must go through D/A conversion, which can adversely affect picture quality.
The resolution to this dilemma is the creation of a complete end-to-end standard digital video interface, such as
DVI. The DVI interface is a high-speed digital video interface allowing uncompressed high-definition content to
be passed to another DVI equipped device such as an HDTVTM set. DVI is the only digital interface capable of
