SDI Outputs
Identical signals are present on each of the paired output connectors on the back of the
Video Processor Frame. All of the outputs carry the same video format, as determined by
the standard selected and by the reference signals connected.
Reference Input
The GV K-Frame XP Video Processor has referencing that can lock to any digital input video
signal or one analog looping reference input. Each can be used with any SD/HD/3G/4K
standard.
Note:
The Frame Operating Mode does not automatically set to the
reference input and does not follow the input sync rate. The Frame Operating
Mode is set in the Eng Setup, Video Settings menu.
For the analog looping reference input, 75-ohm termination of the looping input can be
used either directly, on the adjacent connector, or at the end of a daisy chain looping to
other equipment.
Input Sync Rates will show ‘Locked’ in the Frame Status pane of the Eng Setup, Video
Settings menu when the Frame Operating Mode matches an evenly divisible input
reference frequency. For example, if your reference is NTSC color black (frame rate 29.97Hz,
field rate 59.94Hz) you can select any Frame Operating Mode that has a vertical rate of
29.97Hz or 59.94Hz.

Ethernet switch, to the bottom left (of the four) 100BT/1000BT Ethernet ports on the
Summit/Solo backplane. Refer to the K2 Summit/Solo manuals included with the your K2
