Video and Key Outputs J17ÐJ24 and J33ÐJ38

Connect the video and key outputs to any desired destinations. Output
delay is approximately 63 µs relative to the inputs. Digital outputs conform
to CCIR 601 4:2:2 component digital video standards and may be either
serial or parallel, depending on which output options have been ordered.
All outputs match the line rate of the reference input (525 or 625). Because
outputs are optional, some outputs mentioned here may not be present in
your system.

Program (PGM) Output

The Program Output is the main signal output of the switcher. There may
be up to three identical Program outputs: PGM OUT 1 J19 (parallel digital),
PGM OUT 2 J23 (serial digital), and PGM ANALOG OUTPUTS J33ÐJ35
(analog component).

Program Key Output

The Program Key Output is a luminance key signal derived from the
Program video output. There may be up to two identical Program Key
outputs: PGM KEY OUT 1 J20 (parallel digital) and PGM KEY OUT 2 J24
(serial digital).

Preview (PVW) Output

The Preview Output, which is available only if the Preview Mixer and a
Preview Output option are installed, shows what the switcher output will
look like after the next transition occurs. Up to two identical outputs are
available: PVW OUT J22 (serial digital) and PVW ANALOG OUTPUT J36Ð
J38 (analog component).

Clean Feed Output

The Clean Feed Output J21 (serial digital) consists of PGM video minus the
downstream key.

Aux Bus/Effects Send Outputs

AUX OUT 1 J17 and AUX OUT 2 J18 provide outputs (parallel digital) for
Aux Buses 1 and 2, respectively, if the Aux Output option is installed.
When Effects Send mode is selected, J17 provides the Effects Send Key
Output, and J18 provides the Effects Send Fill Video Output.
