Connecting a Video Capture Device
NOTE: To take advantage of the AV input port, the Video Capture driver supplied with
your computer must be installed (see chapter 6 for details).
Your computer has an AV input port on the rear of the computer for
connecting a video capture device such as high-quality CCD, as well as
consumer electronic equipment such as DVCAM and VCR.
To connect a video capturing device, simply plug the device cable to the
AV input port (conexant 878A PCI; BNC-type) of the system.
