Configuring the S-Video Mode
BYTE Set_S_VideoEx(WORD nDevNo, BYTE input);
Input: MINIDIN = Mini DIN socket is the input
AUTO = automatic configuration
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 = Memory storage of the COMBI socket
NO_SIGNAL = signal not found (AUTO mode)
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.
