Chapter 3: Operation
Input and Output Standards
The Output Video Standard parameter and the Input Video Standard
parameters are related in their function. If Auto is selected in the Input
Video Standard, the Output Video Standard will select either 1080i
(interlaced) or 720p (progressive) and the frame rate will follow. If
Auto is selected in the Input Video Standard, the module will accept
the incoming format (525 or 625) and the frame rate will follow (that is,
1080i/720p at 59.94 or 50, respectively).
If you require an output that always has the same frame rate (for
example, 1080i/59.94 or 1080i/50), select either 525 or 625,
respectively, as an input standard. In this configuration, if the input
changes, the other standard will be treated as loss of video—for which
you can designate Pass, Black, Freeze, or Test Pattern handling.
An HD signal that is fed into the input when Auto is selected will place
the module in Bypass mode if the frame rate in the input and output are
the same. If the input HD signal has a different frame rate than the
output, the loss-of-video circuit will be enabled; the signal cannot enter
Bypass.
