About GV K-Frame XP Compact Source Definition Inputs
The GV K-Frame XP supports a maximum configuration of 80 inputs: 4 boards with 16
inputs (80 inputs) and 2 boards with eight inputs (16 inputs). Up to two Media Ports (one
per board) can be added by installing the 8x4 SDI Conversion I/O boards in the Mod I/O
board slots.

Change Direct Source Definition
1 Select Eng Setup , Source Definition in the menu.
2 Select a Source from the scrolling list located on left side of the screen.
3 Select the Engineering Name data pad to name the source using the pop up
alphanumeric keypad or standard keyboard. Up to 30 characters can be entered, but
shorter names are recommended.
4 Select the
Video Input
data pad to enter or scroll to the input number of the connector
the source will use for video. The change is immediate and can be viewed on a
connected monitor.
5 If the source includes a key signal, select Linear key with the lower touch buttons. Then
select the Key Input data pad and enter to the input number of the connector the
source will use for the key.
6 For Chroma keys you can select either Linear or No Key . Chroma keys always use the
video signal for keying, ignoring any separate key signal.
7 If desired, define
Clip High
and
Clip Low
values (used when a fixed linear key is selected
for that source) with the labeled soft knobs and data pads.
Source Naming Background Information
Facility engineers need to know the exact routing of all the video signals connecting all the
devices they are responsible for. These engineers need to be able to identify video signals in
a way that will help them connect devices properly. Production personnel, on the other
hand, are interested in the content they work with for their shows, and are generally not
concerned about which individual device or routing path is used to make those signals
available. They just need a way to identify the content and access it when they need it. To
support these differing needs, two source naming mechanisms are available on GV K-Frame
XP systems.
Engineering Names, Eng IDs, and Logical IDs
Engineering names are intended to identify a source as it applies to a specific facility. In a
truck, for example, cameras may be hard wired to the production switcher and might be
given Engineering names 1, 2, and 3. Names like Patch 14 or Rtr 5 may be
