This menu item is used to set the contents of the user bits for the LTC and
VITC generators. All the LTC and VITC generators will operate in the same
user bit mode, although the actual user bits may vary from generator to
generator depending on the mode chosen and the respective time zone
being applied to the generator. Four of the user bit modes encode date
information into the user bits in various modes. This date information will be
the system date compensated for any time zone or daylight saving time
adjustments being applied to a particular output.
Select Legacy date to output the date in a format compatible with Leitch
master clock systems.
Select Production date to output the date in a format compatible with Time
code smart slates used in film and television production. In this mode the
date is encoded as yymmddrr, where rr is the nominal frame rate of the
respective output (30 for 29.97 Hz outputs).
Select SMPTE BCD date to output the date in the SMPTE 309M standard
BCD mode. In this mode the date is encoded as zzyymmdd, where zz is
the time zone of the respective output.
Select SMPTE MJD date to output the date in the SMPTE 309M standard
Modified Julian Date mode. In this mode the date is encoded as zzdddddd,
where zz is the time zone of the respective output and dddddd is the date
expressed in its Modified Julian Date representation.
Select Manual entry t o output the user bits that are entered using the Set
User Bits menu item.
Select Lat/Long to embed location information in the user bits. This is only
valid when a GPS clock is being used. Fields with even numbered frames
contain longitude in the user bits, and fields with odd numbered frames
contain latitude. Note that this gives the location of the antenna, and not the
5600MSC.
The format for latitude is wxxxyyzz where w is 1 for south, and 2 for north.
xxx is degrees, yy is minutes, and zz is fractions of minutes.
The format for longitude is wxxxyyzz where w is 3 for west, and 4 for east.
xxx is degrees, yy is minutes, and zz is fractions of minutes.
For example, at Evertz Microsystems factory, the data is:
which corresponds to 43 degrees, 20.49 minutes north and 79 degrees,
46.23 minutes west.
