Parameter Default Setting range Description
TRIGGER DISABLE
DISABLE
ENABLE
Enables or disables auto changeover
for SDI video CRC error.
DURATION IMMEDIATE
IMMEDIATE
1 to 100 FRAMES
Sets the detected video CRC error
duration required to trigger a
changeover.
* To avoid an unexpected changeover
triggered by a switchover of input
signals via router, set DURATION to
longer than 2 frames.
* The “CHGOV DISABLED” message is displayed if CHANGEOVER is disabled in the
VIDEO INPUT SET (5-7-1) menu or VIDEO TRG is disabled in the CHGOV
(CHANGEOVER) MODE SET (5-7-4) menu. If this message is displayed, a changeover
will not be performed even though CRC ERROR TRG is enabled.
* CRC ERROR TRG also triggers a changeover for SDI input signal loss. If CRC ERROR
TRG is enabled and the SDI signal input is lost, a changeover will be performed, even
though SDI ERROR TRG is disabled, based on the CRC ERROR TRG DURATION
setting.
* “CRC ERROR TRG” (5-7-7) also detects TRS errors in blanking intervals as well as in the
active picture area, while “SDI ERROR TRG” (5-7-5) detects them only in the active picture
area. A changeover according to a TRS error in a blanking interval can only be triggered by
“CRC ERROR TRG” (5-7-7).
