28 Chapter 4: Matrox RadientPro CL hardware reference
Matrox RadientPro CL hardware reference
This chapter provides information on the Matrox RadientPro CL hardware. It
covers the architecture, features, and modes of the board’s acquisition section. In
addition, the chapter covers the Matrox RadientPro CL hardware related to the
processing and transfer of data. A summary of the features of Matrox RadientPro
CL, as well as pin assignments for the various connectors, can be found in
Acquisition path
This manual uses the term acquisition path to refer to a path that has the capability
to, for example, capture a component or stream of the video input signal. The
term
independent acquisition path
is used to refer to an acquisition path that can,
if required, acquire data from a video source independently from another such
path on the same frame grabber. Each independent acquisition path has its own
programmable synchronization generator (PSG) to manage all video timing,
synchronization, triggering, timer, and user input and output signals for the path.
MIL-Lite uses the concept of a MIL digitizer to represent the acquisition path(s)
with which to grab from one input source of the specified type. When several MIL
digitizers are allocated, their device number along with their DCF identify if they
represent the same path(s) (but perhaps for a different input format) or
independent path(s) for simultaneous acquisition.
Digitizer
configuration format
To program the acquisition section, allocate a MIL digitizer using
MdigAlloc()
with an appropriate DCF (supplied or created) and digitizer device number. If
you find a DCF file that is suitable for your video source, but you need to adjust
some of the more common settings, you can do so directly, without adjusting the
file, using the appropriate MIL-Lite function. For more specialized adjustments,
use the Matrox Intellicam program to adjust the DCF file. Using Matrox
Intellicam, you can set the active video region, the sampling clock, and all the
other parameters related to the timing of the video signal (that is, standard and
non-standard video, interlaced or non-interlaced) in your DCF file.
