Matrox Vio Duo acquisition section 29
A built-in multiplexer allows for connectivity to multiple video sources and
internal current and voltage clamps ensure the removal of DC offsets from the
input video signal. Three 12-bit A/D converters then digitize the analog video
signal into a 20-bit YCbCr pixel stream. The video decoder has an adaptive
multi-line comb filter for enhanced chrominance and luminance separation of
composite video signals.
The video decoder also features automatic gain control (AGC). This allows the
video signal processing range to be optimized before being digitized. You can,
however, disable the AGC and set the gain manually, using the MIL-Lite function
MdigControl() function with M_GRAB_AUTOMATIC_INPUT_GAIN set to
M_DISABLE and M_GRAB_INPUT_GAIN set to any integer value between
0 to 255.
