5.4.1.2.5. Selecting When the VITC Time is Synchronized to the System Time
This menu item allows the user to set the time of day when the VITC on the
sync output will be synchronized to the system time. This synchronization is
necessary once per day to maintain a long-term correlation between the
VITC time and system time for the NTSC-M sync format.
When the time reference is set to GPS, the VITC output time will have to be
synchronized to the system time to correct for leap seconds. This affects
both NTSC-M and PAL-B formats.
Enter the hour and minute with the and
buttons or by turning the
control knob.
The VITC can also be synchronized to system time immediately using the
Jam Output
menu item. All LTC and VITC timecode outputs can be
synchronized to system time in one shot using the Jam all VitcLtc menu
item.
This menu item is only applicable when the Sync Mode is set to the PAL-B
or NTSC-M formats and will disabled for other formats (shown in dark text).
5.4.1.2.6. Synchronizing the VITC to System Time Immediately
This menu item allows the user to synchronize the VITC on the sync output
to system time immediately. This synchronization will also happen once per
day at the time specified using the Set Jam Time menu item. Caution: This
menu item is a live control.
To synchronize the VITC on the sync output to system time immediately,
select the Jam Output menu item and press the SELECT button. The left
LCD screen will display TIME JAMMED in yellow for 2 seconds.
This menu item is only applicable when the Sync Mode is set to the PAL-B
or NTSC-M formats and will disabled for other formats (shown in dark text).
When the time reference is set to VITC or LTC and the frame rate of the time
reference is the same as the sync output, the time will be jammed directly from the
time reference rather than from system time.
