videocmd(3G)

NAME
     videocmd - initiates a command transfer sequence on a video peripheral

C SPECIFICATION
     void videocmd(cmd)
     long cmd;

PARAMETERS
     cmd   expects a command value which initiates a command transfer sequence
           on a video peripheral.  The valid command tokens are:

           VP_INITNTSC_COMP initialize the Live Video Digitizer for a
           composite NTSC video source.

           VP_INITNTSC_RGB initialize the Live Video Digitizer for a RGB NTSC
           video source.

           VP_INITPAL_COMP initialize the Live Video Digitizer for a composite
           PAL video source.

           VP_INITPAL_RGB initialize the Live Video Digitizer for a RGB PAL
           video source.

DESCRIPTION
     videocmd allows you to initialize the Live Video Digitizer peripheral
     board.  Four command tokens are recognized; these initialize the board
     for either an NTSC video source (composite or RGB) or a PAL video source
     (composite or RGB).
