Black Time Code Settings
Note : The Black Time code settings are available only when a non - HD format is
set as the signal format of the selected Black output.
Source
Select the drop- down list and choose the time code source. The default value is
Disable.
Disable: Disables the time code function for the selected Black output.
Local (DST): Uses the local time of day with Daylight Savings Time offset
as the time code.
Local (No DST): Uses the local time of day without Daylight Savings Time
offset as the time code.
UTC: Uses Coordinated Universal Time as the time code.
Program Time: Uses the program time counter as the time code.
Note : In addition to enabling the time code source, at least one line must be
specified and enabled to carry a VITC signal.
Offset
Enter an offset for the selected Black output, relative to the selected time code
source in the format ±HH:MM:SS:FF. You can enter a time offset of up to
±23:59:59:29 (maximum frame value depends on the frame rate of the video
signal).
Note : The Offset adjustment allows you to enter a time zone correction of up to
±23:59 hours. However, the ST309 standard only implements codes for time
zones in the range of -12 to +13 hours ; when you are using ST309 data as the Time
of Day source, we recommend limiting the combined programmed offset from
time zone and daylight savings time to the range of -12 to +13 hours.
VITC 1 and 2 Line
selections
Use these menu items to insert the same VITC signal on 1 or 2 lines of the vertical
interval.
Enter the video line number to insert the selected VITC signal. For NTSC, you
can select lines from line 10 to 20 (lines 14 and 16 are recommended). For PAL,
you can select lines between 6 and 22 (lines 19 and 21 are recommended).
Select the Enable check box for the selected line to enable or disable the output
of a VITC signal.
