Background Video
Next we will connect the background video source. The background video is the footage that you want
behind your subject in the finished keyed video. A few examples of backgrounds would be a virtual studio, or
a weather map or perhaps a famous building or landmark. You can feed any video signal as the background
source; most often the footage will be coming from a Deck or DVD Player.
DVD Players and VCRs generally have one of two types of video output:
Most DVD Players and VCRs have outputs like these, although the
layout may differ slightly. There is a mini 4 pin din socket for S-Video
(Y/C) out, and a RCA / Phono socket (almost always colour coded
yellow) for Composite Video Out. In addition there will be two RCA /
Phono sockets for left and right audio (almost always colour coded
white and red).
Some DVD Players and VCRs (mostly in Europe) use a SCART
connector instead of the above. A SCART connector carries many
different types of signal in one multi pin socket. The easiest thing to
do if you have a SCART connector is to purchase a SCART to RCA /
Phono Adaptor as illustrated below.
SCART ADAPTOR
with In / Out Switch
A SCART Adaptor simply plugs into the SCART Socket and
breaks it out to RCA / Phono Sockets. Some adaptors have an
Input / Output switch which changes the direction of the
connections, whereas others are specified as In or Out only.
Some adaptors have an S-Video Socket whereas others do not.
If you are buying a SCART adaptor for your playback device
make sure that it is an OUT adaptor.
N.B. If your VCR or DVD Player does not support S-Video output
via the SCART connection, using an S-Video port on a SCART
Adaptor will only give you a black & white picture.

If your player has an S-Video Out connect it to the BG (Background) S-Video Input on the DVK-200 rear
As you are using an S-Video connection, set the BG Input Select Switch to S Input

If your player does not have an S-Video Out, connect the Composite Video Out (Yellow
RCA/Phono) to the BG Composite Video BNC Input on the rear of the DVK-200.
(You may need a BNC to RCA / Phono Adaptor to connect the BNC cable to your player)
As you are using a Composite Video connection, set the BG Input Select Switch to CV
