Each of the 16 MatchDef buttons report the current source, format, and crop
status for that input.
The Enable buttons activate and deactivate conversion for the individual
input connector button located immediately above.
The currently operating Karrera video standard is shown in the System Video
Format status display on the upper right portion of the menu.
Auto Line-Rate Enable – When on, the Karrera system detects the input video
format and automatically chooses the appropriate line rate for the selected
input. One frame of video is required for detection. If the incoming video
signal format changes, one incorrect frame of video will be displayed.
When Auto Line-Rate Enable is on, the 720p, 1080i, and SDi buttons below
are inactive.
Note If the incoming source has a noisy signal, choosing the correct line rate man-
ually may provide better performance.
