Acquisition section 33
Acquisition section
The acquisition section of Matrox Morphis QxT can capture RS-170/CCIR
monochrome video and composite (CVBS) video in NTSC /PAL format. The
acquisition section of Matrox Morphis QxT has 16 independent acquisition paths.
These independent acquisition paths allow Matrox Morphis QxT to
simultaneously capture from any 16 connected, supported, synchronous or
asynchronous video sources.
The following diagram illustrates the main components of the acquisition section
of Matrox Morphis QxT.
To grab from a video source, allocate a MIL digitizer with a DCF that matches
the video source’s data type, using the MIL-Lite
MdigAlloc() function; a MIL
digitizer represents the acquisition path(s) with which to grab from one input
source of the specified type. Then, using the returned MIL digitizer identifier, call
MdigGrab() .
To grab video data from multiple video sources simultaneously, allocate the
appropriate number of digitizers with
MdigAlloc() and specify a different device
number for each. Then, using the returned MIL digitizer identifiers, call
MdigGrab() .
