Video Reference
The flexible reference system in the switcher allows
you to use an Interlaced video format as the reference
to operate the switcher in a video format of the same
frequency. Choosing a progressive video format as a
reference limits you to operating the switcher only in
that same video format and frequency.
Supported Reference Formats
The switcher supports a number of reference modes for
both internal and external reference signals. References
to 1080p 59.94Hz (A) and 1080p 50Hz (A) refer to
1080p Level A only.

The switcher allows you to use any interlaced video
format to operate the switcher in any format of
the same frequency; however, the use of 480i or
576i (Composite Sync) reference signals for High
Definition (720p, 1080i, or 1080p) video modes is not
recommended.
The use of composite sync reference formats
is recommended for Standard Definition video
modes only, and provides stable outputs with jitter
performance in compliance with SMPTE-259M
specifications.
Reference and Video Mode Setup
The switcher supports both internal and external
references. An external reference is provided by an
external device to the switcher through the
REF IN
BNC on the frame. An internal reference is generated
by the switcher and can be fed out to other devices.
The switcher automatically detects the reference signal
and only shows the video modes that you can operate
the switcher in that are supported for that reference
format.
To Set a Video Mode
If you are using an external reference, ensure that a
proper reference is connected to the REF IN input
BNC on the frame.
Note: You must use an interlaced reference source to have
the switcher operate in an interlaced reference format if you
are using an external reference.
