B.3.2 No Video Output
•
Check that the correct standard SDI monitor is connected to the chosen output.
Note: Some monitors only support a limited number of video standards.
•
Check that a valid input is routed to the appropriate video channel. To do this:
1.
On the front panel, press the CH SELECT button to select an unused processing
channel.
2
Press the INPUT Shortcut button.
3
From the Input Select menu, choose the SDI input that has a valid video source.
You can create a valid video source from any of the two or four channel products by
setting up a test pattern on any of the unused channels. To do this:
1.
On the front panel, press the CH SELECT button to select an unused processing
channel.
2
Press the OUTPUT Shortcut button.
3
Select Test Patterns and choose Ramp or Bars to create a suitable test pattern.
•
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.
2
Select Test Patterns and make sure that the Off radio button is selected.
