IP Network Grand Master Clock & Video Master Clock System
Page - 76 Revision 0.2
5.3.2. Configuring the Time Inputs
5.3.2.1. Selecting the Time Reference
INPUT
The Reference Src menu item in the Time Reference Src menu is used to
select the time reference that the 5700MSC-IP will use to lock its internal
clock. All outputs are driven from this common time source
When set to GNSS, time data is obtained from the GPS and / or GLONASS
satellite constellations. This is the most accurate source of time reference
available
When set to LTC, the 5700MSC-IP obtains time from an LTC clock wired to
its LTC input.
When set to VITC, the 5700MSC-
IP obtains time from Video reference
wired to the Reference Loop Thru HD-BNC connectors, or Frame Reference
1 or Frame Reference 2 BNC connectors, depending on how the Frequency
Reference Genlock Source is configured. Note that this Video reference can
only be NTSC-M or PAL format, and must have VITC time code present.
When set to None, the internal clock of the 5700MSC-
IP is in “free run”
state, and regulated by the extremely accurate ovenized oscillator, resulting
in a drift of less than one millisecond per day.
When set to IRIG, the 5700MSC-IP obtains time from the LTC input using
the IRIG protocol.
When set to SNTP, the 5700MSC-
IP obtains time via any of its network
interfaces (
Gigabit Ethernet 1, Gigabit Ethernet 2, 10G Ethernet 1, 10G
Ethernet 2 and Frame Ethernet) from the first available configured SNTP
server.
When set to 1588, the 5700MSC-IP obtains time
from the best available
PTP Master found on its network interfaces:
Gigabit Ethernet 1, Gigabit
Ethernet 2, 10G Ethernet 1, 10G Ethernet 2 and Frame Ethernet. The PTP
BMCA (Best Master Clock Agorithm) is used to establish which PTP clock in
each PTP doma
in assumes the role of active PTP Master, while all other
potential masters enter into a passive state. The network interface on this
5700MSC-IP that is used to lock to a PTP Master will enter into Slave state.

5.3.2.2. Setting the VITC Reader Line
INPUT
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/In time status
screen.
