Chapter 3, Using Your Matrox MC-100 Hardware
MC-100 channel definitions
Matrox MC-100 can process up to two video channels at one time. Use the
following channel definitions when specifying the output settings:
• For all input video signals except 3G level B, channel 1 refers to the input
signal on SDI 1, and channel 2 refers to the input signal on SDI 2.
• If one 3G level B input video signal is connected to MC-100, channel 1 and
channel 2 refer to the two channels in the 3G level B signal. If you connect
two 3G level B input signals, channel 1 and channel 2 refer to the two
channels in input SDI 1, and the 3G level B signal connected to SDI 2 can be
output using the
SDI 2 bypass option only (see “Specifying your output
settings” on page 17 ).
• When you select the Channel 1 , Channel 2 , 3D , Analysis , or Multiplex
option for a given output (see “Specifying your output settings” on page 17 ),
channel 1 and/or channel 2 is output using the current MC-100 settings. If
you want to output an input video signal without applying the MC-100
settings, choose the
SDI 1 bypass or SDI 2 bypass output option instead.
Amplifying input signals
MC-100 also functions as an input signal amplifier. Input signals connected to
MC-100 are automatically amplified within MC-100. This allows you to transfer
the SDI and HDMI output signals over greater distances. The distances for the
different input types are as follows:
• SD 300 meters (984 feet)
• HD 100 meters (328 feet)
• 3G 70 meters (229 feet)
Time base correction and synchronization
When input sources are connected to SDI 1 and SDI 2, MC-100’s time base
corrector ensures that the two video signals are synchronized at the output by
using the video signal that is set as the reference source (see
“Specifying your
input settings” on page 15 ) to correct the other video signal. MC-100’s time base
does not correct the audio portion of the signal.
¦ Note The time base corrector does not apply when using the SDI 1 bypass or
SDI 2 bypass output setting (see “Specifying your output settings” on page 17 ).
This means that if the two input sources are not synchronized using an external
reference source, the input signals may not be synchronized at the output.
Depending on the amount of discrepancy between the two input signal clocks,
the input signal that is not set as the reference source may not be output.
