9-2-1-2. Changeover and Loss Operation (Web)
Changeover has priority over Loss operation conducted by Video Loss Mode. However, if
neither a SDI 1 or SDI 2 input signal exists, the FA-9500 performs LOSS according to the
selection made under LOSS in the 9-2-1 Input Select menu. If both SDI 1 and 2 inputs
encounter the same problem and the problem is not signal loss, the FA-9500 will output
the SDI 1 input signal.
9-2-1-3. Changeover and Input Switchover Using a Router (Web)
An SDI 1 input signal switchover conducted via router will be detected as an error by the
CRC Error Trigger and Audio Error Trigger in section 9-2-1 Input Select. If either trigger
has been enabled for a short duration, a changeover will occur. To avoid such input
switchover-triggered changeovers, set DURATION under CRC Error Trigger to longer
than 2 frames, and DURATION under Audio Error Trigger to longer than 0.2 sec..
9-2-1-4. How to Reset to SDI 1 (Main Input) (Web)
This section describes how to reset input to SDI 1 after a Changeover.
1) Check the 9-7-5 Changeover Status menu to verify what caused the changeover.
2) Resolve the issue(s).
3) Check that the issue(s) is/are resolved using a waveform monitor.
4) Disable Changeover. (The status menu will be reset.)
5) Select SDI 1 under Input Select.
6) Enable Changeover again.
