3.4 Timecode Menu
Each Video output has a counting timecode channel associated with it:
SDI 1 and SDI Black 1 output
SDI 2 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:
LTC 1
LTC 2
LTC 3
LTC 4
There are five counting times that are important in the system. These are:
SPG Time
UTC DateTime
GPS DateTime – extracted from the optional GPS receiver
NTP DateTime – extracted from a suitable NTP server via the Ethernet interface
Analog Video Reference VITC – extracted from VITC on the analog video reference #
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 DateTime is locked to one of Real Time Clock (RTC), GPS DateTime, NTP DateTime or
Analog Ref VITC.
SPG Time is locked to UTC DateTime. UTC DateTime is the datum from which SPG Time is offset.
SPG Time is the central time to which all Video and LTC timecodes are locked. 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.
See Figure 1.2d : CY460 SPG – Timecode in Section 1.2 : Functional Diagrams for a functional
diagram of the CY460 Timecode system.
See Figure 3.2 : CY460 SPG – Setting Time and Date Parameters at the end of this section for a
flowchart outlining the procedure to initially set your local time and date parameters.
