Outputs
The outputs on the back of the Video Processor frame are numbered 1
through 12 and 13 through 24 on the 4RU frame. All of the outputs carry
the same video format, as determined by standard selected and by the ref-
erence signals connected. The number of outputs that are active depends
on the number of full mix/effects or I/O Expansion modules installed in
the chassis. There are 12 outputs active for every mix/effects and expansion
module installed.
Reference Input
There are two separate, looping reference input pairs. The upper pair
accepts analog 525 or 625 composite video. Burst is not required, but typi-
cally facility reference color black is used. Kayak HD can auto-sense
whether the reference is 525 or 625 and can change the internal standard
accordingly.
The lower looping reference input pair is for HD production and uses
analog tri-level sync.
75-ohm termination of one of each of these looping inputs is required,
either directly on the adjacent connector or at the end of a daisy chain
looping to other equipment.
Any one of the SDI inputs can also be used as reference in the respective
standard.
