eight as defined in the SMPTE time code specification. The "87:65:43:21" numbers shown here are not the
actual user bit values, but instead indicate where the so numbered "groups" of user bits are displayed by the
TVC-50.

UB DATE
Selects the format for
HORITA
FMT
:
how the "date" data is
LEITCH
decoded (interpreted)
from the user bits of
the time code.
For HORITA this is ZZ:YY:MM:DD for the 87:65:43:21 user bits, where ZZ is the time zone, YY is the year, MM the month
and DD the day. For LEITCH the encoding does not have the date data in an order that is easily describable here.
CLOCK/CALENDAR
TIME HMS
:
HH:MM:SS User settable
HH = 00-23 hours
hours, minutes, and seconds MM = 00-59 minutes
time value of internal clock. SS = 00-59 seconds
The time display here
is always in the 24 hour
"military" time format.
DATE MDY
:
MM-DD-YY User settable MM = 01-12 months
day, month, year value of the DD = 01-31 days
internal
internal (clock) calendar The YY = 00-99 years
date display here is always in
this MDY format.
JAM TIME: Preset internal clock time to Y = Do Jam
that of the SMPTE time code N = NO or Jam performed
time value.
Invalid values of time code cannot jam the time. When the time jam is first selected, the selection momentarily
changes from "N" to "Y", then back to "N" to indicate that the jam function has been performed. This takes from
one to two seconds. If this sequence is not observed, then the jam operation did not occur and should be
attempted again.
JAM DATE
:
Preset internal clock date to
Y = Do Jam operation
that of the SMPTE time code N = NO or Jam performed
user bit date value.
Note that invalid user bit date values cannot jam the date. When the date jam is first selected, the selection
momentarily changes from "N" to "Y", then back to "N" to indicate that the jam function has been performed.
This takes from one to two seconds. If this sequence is not observed, then the jam operation did not occur and
should be attempted again.

This setup menu allows setting up of the TVC-50 time and date displays. The displays can be turned ON or OFF, the position
and format changed and the time and date reference selected.
The first menu items are for setting up the time display.
