Grab features
The Matrox CronosPlus board is equipped with a video decoder chip that has an
integrated PCI interface. The chip can grab RS-170 /CCIR monochrome video
and composite (CVBS) and component (Y/C) video in NTSC /PAL format.
Performance
The video timing parameters supported by Matrox CronosPlus are as follows:
F i e l d r a t e ( H z )
P i x e l / l i n e ( P i x e l s )

Input channels
With Matrox CronosPlus, you can only acquire data from one video source at a
time; however, you can attach several video sources and switch between them.
The Matrox CronosPlus board can switch between up to four independent
composite/monochrome sources. Alternatively, the board can switch between
1 Y/C and 3 composite/monochrome sources.
To switch between video sources of the same type, allocate a single digitizer (using
the MIL-Lite function MdigAlloc()) and switch between the input channels
(using the MIL-Lite function MdigControl() with M_CHANNEL
*. As of MIL 10.
