S-video and composite video
The Marvel connector box has two composite
video
connectors (one input and one output),
and two
S-video connectors (one input and one
output). Most video equipment uses composite
video, but some devices (for example, S-VHS
VCRs) use S-video, which is a higher quality
video signal.
If you have a video device with S-video
connectors, you should use a Matrox
S-VIDEO IN or S-VIDEO OUT connector. If your
S-video device didn’t come with S-video
cables, this type of cable is available at most
electronics stores.
You can use the Matrox S-video connectors
instead of – or in addition to – the composite
video connectors. If you use composite and
S-video connectors, you can connect up to four
video devices to Matrox Marvel at the same
time (two input and two output).
Matrox Marvel video output is
simultaneous
on its composite (
VIDEO OUT ) and S-video
(
S-VIDEO OUT ) lines.
Both video input types may be connected at the
same time, but only one video input signal at a
time can be used by Matrox Marvel. You need
to select either the composite video (
VIDEO IN )
or S-video (
S-VIDEO IN ) signal in the software
(see page 34 and page 39).
(Note: Using the Matrox composite
video and S-video connectors at
the same time is optional.)
