Input Channels; Low-Pass Filter; Video Decoder - Matrox Meteor-II /Standard Installation And Hardware Reference

The video timing parameters supported by the Matrox Meteor-II /Standard board
Performance
are as follows:
Field rate (Hz)
Pixel/line (Pixels)
Active pixel/line (Pixels)
Active lines/frame (Lines)
Pixel rate (MHz)
ADC sampling rate (MHz)
Line rate (KHz)

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. A channel is 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 composite (CVBS) or component (Y/C) to digitized component
video. The decoder supports RGB 8:8:8 (24-bit), RGB 5:6:5, YUV 4:2:2, and
YUV 4:1:1 output pixel formats. Note that YUV 4:2:2 output pixel formats are
grabbed as YUYV.
