•
If you are using a composite output, check that your monitor accepts composite
signals.
Note: Only SD outputs can use the CVBS encoders.
•
If you are using composite input sources, check that these are connected to the
correct CVBS inputs. See “Block Diagrams” on page 15.
B.3.3 Front Panel Display is Blank
•
Check that you have valid SDI video on the video channel selected.
•
On the Home screen, check that the correct standard is showing on the status display
for the processing channel in use. If the display shows "Input Loss", check that your
video source is playing out correctly. If there is no input to the processing channel in
use, the right-side of the display is black.
•
If you can see a valid input on the channel status screen and you are sure that the
correct SDI input has been routed to this processing channel, check the test patterns
to ensure that you have not set a black test pattern on the output. To do this:
1.
On the front panel, press the OUTPUT Shortcut button.
b
Select Test Patterns and make sure that the Off radio button is selected.
B.3.4 Composite Input Problems (MC1000/MC2000 Only)
If you are routing a composite signal via one of the CVBS decoders:
•
Check that you have a valid SD composite source. You can create a valid composite
source from any of the two or four channel products by routing an SD test pattern
through the CVBS encoder (if fitted) on the unused channel. To do this:
1.
On the front panel, press the CH SELECT button to select an unused processing
channel.
b
Press the OUTPUT Shortcut button.
c
Select Test Patterns and choose Ramp or Bars to create a suitable test pattern.
d
Press the SYSTEM Shortcut button.
e
Select CVBS and route the appropriate channel through the chosen CVBS
encoder.
If you are having problems with composite inputs:
•
Check that the correct input format is selected for the chosen input connection(s). To
do this:
1.
On the front panel, press the SYSTEM Shortcut button.
b
Select CVBS > CVBS Decoder (A–D) > Source.
c
Scroll until the appropriate radio button for the source is highlighted. For
example, select Input 1 for a PAL signal on CVBS In A1, or Y/C for a signal using
both CVBS in A1 and CVBS In A2.
d
Select Done.
Note:
When using the CVBS inputs or outputs, it is important to remember that they can be used
for single connection composite signals (such as PAL or NTSC) or for Separated Y/C
signals, which use both BNCs.
