Hint: The term “genlock” refers to
“generator locking”.

Professional video devices often
provide a “genlock input”, which
allows an external reference signal
(often referred to as ‘house sync’)
to control its video timing.

The output of video devices
connected in this manner is
synchronized to the reference
signal, and they are referred to as
‘genlocked’.

The physical Display connectors may vary by model, but are typically presented
physically on TriCaster’s rear connection panels as HDMI and either DVI or VGA
ports. No audio is supplied to these connectors.

When a downstream monitor is detected on a Display port, the corresponding
Resolution menu permits selection of a suitable resolution (typically, an incorrect
selection here will result in an ‘out of range’ error message being displayed on the
downstream device).

Switches provided at left in each row permit the Display ports to be selectively
disabled when they are not required.

Note: TriCaster Mini, depending on the model, may also provide CASE DISPLAY setup
features, providing access to a number of useful display alternatives for the side-panel
LCD screen.

8.1.2 GENLOCK & FAILSAFE

TriCaster’s Genlock feature allows it to
‘lock’ its video output to a reference video
signal supplied to its Genlock input
connector. (Note that neither TriCaster 410
nor TriCaster Mini include Genlock
options.)

This synchronizes TriCaster output to other
external equipment locked to the same
reference. Genlocking is not a requirement,
but it is very beneficial, and you should
definitely use it if you have the capability.

TriCaster mixes and switches output from
up to eight camera sources (8-input
models). Miniscule local timing differences
between these may force tiny delays during
switching operations, which can also
contribute to throughput latency.
