System Connections
Like the front panel, the GDV-850's
rear panel is carefully arranged to
make hookup, configuration, and use
as simple as possible. However, the
GDV-850's capabilities take some study
to use most effectively. We strongly
suggest that you read this section of
the manual before beginning to hook
up your player. You will save yourself
much time and effort if you carefully
think out what you expect from your
system, consider the components you
will use, where they'll be placed,
and how you will want them to work
together. The notes in this section and
the connection diagrams that follow
will probably answer most of your
questions about interfacing the GDV-
850 into your system.
[ 11 ] Region Code
The GDV-850 is configured for use in spe-
cific geographic locations. Geographic
regions around the world are assigned a
numeric code by the DVD forum which is
indicated on this icon. See section 7.0 of
this manual for more information.

to a preamp that accepts component
video input or directly to your display. A
component video signal typically refers
to Y/Pb/Pr, which consists of three
75-ohm channels: one for luminance
information, and two for color.
Note: The 480P progressive scan output can only be used with
a digital television capable of displaying or converting 480P images.
[ 13 ] Video Format Switch
With the GDV-850 you have the abil-
ity to switch between progressive-scan
(480p) and an interlaced (480i) video
signal. Use this switch to set the video
output format. When the progressive
output is selected the S-video and
composite outputs are disabled and the
progressive status indicator on the front
panel will illuminate.
[ 14 ] S-video Output
S-video may also be referred to as
Y/C, the abbreviation for luminance/
chrominance. The S-video cable uses
a four-pin connector that is most com-

monly used with VCRs and DVD players.
S-video delivers a better picture than
composite connections and should be
used whenever possible unless you can
use component connections, which typi-
cally deliver better video than S-video.
[ 15 ] Composite Output
Composite video is used in nearly all con-
sumer video devices. Both chrominance
and luminance signals are carried on the
same 75-ohm RCA cable. Chrominance is
carried in a 3.58-mHz (NTSC) sideband
and filtered out by the TV's notch or
comb filter. Poor filtering can result in
dot crawl, hanging dots, or other im-
age artifacts. We recommend using this
output only when component or S-video
inputs are not available.
[ 16 ] RS232 Input
Allows control of the GDV-850 via com-
puter or home automation system. A DB-9
