Configuring the S-Video Mode
BYTE Set_S_VideoEx(WORD nDevNo, BYTE input);
Input: MINIDIN = Mini DIN socket is the input
COMBI = Combi plug (socket X3) is the input
AUTO = automatic configuration
Return
(a) input = MINIDIN or COMBI
SUCCESSFUL = no error occurred
NOT_SUPPORTED = eGrabber-2, EPC-031 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 the cable.
Caution:
The S-Video source can either be connected to the Mini-DIN socket
or alternatively to socket X3. 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.
