Section 3 — K-Frame Cabling
Inputs
Non-looping video inputs on the back of the Video Processor Frame are
numbered 1 through 32 on each input module. Each accepts a 270 MHz,
1.485 Gb, or 3 Gb serial digital video signal. The number of inputs that are
active depends on the number of input modules installed in the chassis.
Outputs
Paired outputs on the back of the Video Processor Frame are numbered 1
through 16 on each output module. Identical signals are present on each of
the paired output connectors. All of the outputs carry the same video
format, as determined by the selected video standard.
MatchDef and SetDef Format Conversion
K-Frame Video Processor modular IO is available for MatchDef and SetDef
signal conversion, or to increase the number of standard video inputs and
outputs. This functionality is configurable in software. The 13-RU Standard
K-Frame can hold up to eight modules, and the 8-RU can hold up to four.
Each modular I/O module has four pairs of connectors, labeled IN 1-4 and
OUT 1-4. The connectors with the same number on that module constitutes
a configurable pair. Three different software settings are available for each
pair of modular I/O connectors:
Reference Input
The K-Frame Video Processor has one analog looping reference input,
which can be used with any SD/HD/3G standard. This reference input
signal must have the same frame rate as the native operating standard of
the K-Frame.
75-ohm termination of the looping input is required, either directly on the
adjacent connector or at the end of a daisy chain looping to other equip-
ment.
