4.3.5. Setting the VITC Reader Line
This menu item is used to specify which line on the black burst reference
input the VITC will be read from. The VITC that is read from the reference
input can be viewed in the STATUS menu on the System/LTC time status
4.3.6. Configuring the VITC and LTC Time Reference Date Format
The Date Mode menu item is used to select how the 5601MSC will decode
date information from the user bits of the VITC and LTC inputs. It is only
valid when the time reference source is set to VITC or LTC.
When set to Auto mode, the 5601MSC will analyze the incoming user bits to
try to find the best date format. Use caution with this as some random data,
including all 0s will look like a valid Legacy date format.
Select No date to ignore the user bits of the incoming VITC and LTC. This
means that if the time reference is set to VITC or LTC the date must be set
manually in the GENERAL menu.
Select Legacy to decode the date in a format compatible with Leitch master
clock systems.
Select Production to decode the date in a format compatible with timecode
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 29.97Hz outputs).
Select SMPTE 309 BCD date to decode the date in the SMPTE ST 309
standard Binary Coded Decimal mode. In this mode the date is encoded as
zzyymmdd, where zz is the time zone of the respective output.
Select SMPTE 309 MJD date to decode the date in the SMPTE ST 309
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.

4.3.7. Selecting the IRIG Input Mode
The Irig Mode menu item is used to set what format of IRIG to expect. It is
valid only when the time reference has been set to IRIG.
See section 2.3.5 for a description on the different IRIG formats supported.
Select B12* AUTO to auto-detect the IRIG type. Otherwise the input IRIG
format can be forced using this control. Note that only IRIG-B127 provides
year information.
B120 to B123
