SYNC HD Guide 10
Synchronization and
Time Code Connections to
Machines, Decks, and Other
Devices
The following sections describe connections re-
quired for different applications. For more infor-
mation on time code applications, see
Appendix A, “Additional Synchronization In-
formation.”
Connecting a Video Source
This section describes connections required
when using house video reference (SD or HD).
To have the SYNC HD resolve to house sync:
„
Connect the house video reference/black
burst/tri-level sync source to the Video Ref In
port on the SYNC HD.
To have the SYNC HD resolve directly to an
incoming SD video signal:
„
Connect an SD video signal to the SYNC HD
Video In port.
Character Generator for Window Burn
The SYNC HD can generate a window burn on
SD signals coming in to the Video In port.
To use the SYNC HD Time Code Character
Generator to make a window burn (SD signal):
1
Connect an SD video signal to the SYNC HD
Video Ref In port.
2
Connect the SYNC HD Video Ref Out port to
the Video In port.
3
Connect the SYNC HD Video Out port to
other video devices, ensuring that the signal is
terminated by the last device in the chain.
Connecting LTC
The SYNC HD provides LTC input and output
connectors.
To input LTC to the SYNC HD:
„
Connect the LTC signal from your machine,
synchronizer or other source to the SYNC HD
LTC In port.
To output LTC from the SYNC HD:
„
Connect the SYNC HD LTC Out port to your
external devices.
The Video Ref ports are a non-terminated
loop-through connection. If the Video Ref
Out port is not used, then you must
terminate it using the included 75-ohm
BNC terminator.
Even when you have an HD video refer-
ence signal connected to the Video Ref In
connector, you can still connect an SD
video signal to the Video In connector to
provide a window burn.
