Matrox Meteor-II /Standard grab section 55
Performance The video timing parameters supported by the Matrox
Meteor-II /Standard board are as follows:
Input channels
Matrox Meteor-II /Standard for PCI and PC/104-Plus can
switch between up to twelve independent composite or six Y/C
video sources. Matrox Meteor-II /Standard for CompactPCI can
switch between seven independent composite sources, or up to
three Y/C video sources.
You can only acquire data from one channel at a time. Channels
can be selected with the MIL-Lite command, MdigChannel().
Low-pass filter
The input low-pass filtering stage is used to limit high
frequency noise and aliasing effects at the input of the decoder.
The filter used on Matrox Meteor-II /Standard for PCI and
CompactPCI is a 4th order Butterworth filter with a cutoff
frequency of 8 MHZ. The filter used on Matrox Meteor-II
/Standard for PC/104-Plus is a single-order filter with a cutoff
frequency of 6 MHz.
Video decoder
A multi-standard video decoder is used to convert NTSC and
PAL analog video signals that are in composite (CVBS), or (Y/C)
formats to digitized component video. The decoder supports
