Timecode Menus
Each Video output has a counting timecode channel associated with it:
• SDI and SDI Black 1 output
• SDI and SDI Black 2 output
• Composite 1 output
• Black 1 output
• Tri-Sync Black 2 output
• Tri-Sync Black 3 output
• Tri-Sync Black 4 output
There are 4 linear counting timecode (LTC) channels:
• LTC1
• LTC2
• LTC3
• LTC4
There are five more counting times that are important in the system. These are:
• SPG Time
• UTC Date Time
• GPS Date Time - extracted from the optional GPS receiver
• NTP Date Time - extracted from a suitable NTP timeserver via the Ethernet interface
There are three more non-counting times that are important in the system. These are:
• Summer DST Event
• Winter DST Event
• Leap Second Event
UTC Date Time is locked to one of Real Time Clock (RTC), GPS Date Time, NTP Date Time, or
Analog Ref VITC.
SPG Time is locked to UTC Date Time. UTC Date Time is the datum from which SPG Time is
offset. The central time to which all Video and LTC timecodes are locked is SPG Time. SPG
Time is also the datum from which all Video and LTC timecodes are offset.
Summer DST Event, Winter DST Event and Leap Second Event each define times and dates at
which TC-events occur.
The inter-relationships between the times and timecode is fixed. Only the offsets and TC-events
affect the times for each timecode.
