Bus Link Mode
The Bus Link Mode allows you to establish a relationship between the crosspoints
of different switcher buses. The mode has valuable applications in both live and
post production situations:
•
With a link established in a live broadcast, for example, selecting
camera one on M/E 2 could automatically select camera one on an
Aux bus. Offsets can also be established through the use of up to five
“link relationship tables” — allowing you to select the same source or
a different source on another bus, as required.
•
In post production, for example, the Bus Link Mode would allow you
to automatically select M/E 2 key matte on Aux 13, each time M/E 2 is
used as the program output source.
GPI Link Mode
The GPI Link Mode allows you to establish a relationship between switcher
crosspoints and the switcher’s GPI output ports. A variable timing relationship can
be established between the crosspoint selection and GPI outputs. For a virtual
studio application, for example, selecting a camera (on a switcher bus) would
trigger a GPI pulse that in turn switches computer-generated virtual backgrounds.
This action also delays the actual video switch by a certain number of fields —
allowing the background and foreground to switch in sync.
In operation, the GPI Link can be advanced or delayed from the initial “press” of
the switcher crosspoint.
