Input:
MINIDIN

Return
(a) input =
MINIDIN or COMBI
SUCCESSFUL
= no error occurred
NOT_SUPPORTED = pciGrabber-4 (old model) and
the COMBI parameter
(b) input
= AUTO
MINIDIN
= Memory storage from the Mini-DIN
socket
COMBI

NO_SIGNAL

The video processor’s second ADC must be activated when
connecting an S-Video source. The function
Set_S_Video
activates
the
chroma ADC
. The excessive luma notch filter in the Luma path is
deactivated, creating a sharper image.
Set_S_Video
also
automatically connects the input channel to the S-Video input.
S-Video sources are color cameras that have a special output in order
to separate brightness and color signals. These cameras can be
connected to a Grabber with either the WK051 cable.
Caution:
An S-Video source can either be connected to the Mini DIN socket or
to the lower HD-DB-15 socket.
The S-Video source can not be
connected to both sockets simultaneously!
The function has a hand-over parameter that specifies which socket
the S-Video camera is connected to. If
AUTO
is given as a parameter,
then the driver searches for the S-Video camera. The driver first tests
the Mini DIN socket for an active signal.
