Tip: Reference settings can also be set up from the Reference
tab on the Configuration node in DashBoard.
1.
Press MENU > REF.
2.
Use the VidMode knob to select the video
format that you want to use.
The available video modes depends on the
reference format coming into the switcher.
3.
Press NEXT.
4.
Use the RefSrc knob to select an internal (Int)
or external (Ext) reference source.
5.
Press the RefSrc knob to conrm the reference
source.
Frame Sync and Format Conversion
The switcher has multiple input frame synchronizer /
format converter (FSFC) and input de-interlacers that
can be used to convert video input signals to the format
that the switcher is operating in, as well as correct
mistimed, or drifting, video input signal. The frame
synchronizers cannot completely correct badly formatted
video, mistimed switches, signal drops, or similar issues.
Each FSFC channel maintains a separate setting for
different video formats. This lets you change between
video formats without losing FSFC channel
congurations.
Keep the following in mind when working with Frame
Converters and Synchronizers:
• If a video format not compatible with the currently
dened conversion is used, the video image is
frozen with the last successfully processed image
frame.
• FSFC create a one-frame delay in the video output
of the switcher for the video signal being converted.
• FSFC strips embedded audio data from the video
signal. Ensure that no FSFC channels are assigned
to any input or bus you are using with external
audio mode.
• In the Carbonite and Carbonite eXtreme frames,
FSFC channels are assigned to either specic video
inputs or bus-pairs. Each bus-pair requires two
FSFC for key video and key alpha, or program and
preset. Aux buses do not require bus-pairs.
• If one FSFC channel in a bus-pair is turned off, the
paired FSFC channel is also turned off.
• The switcher is set to switch on the rst eld when
using Bus mode.
Supported FSFC Input Mode Video Formats
FSFC can only convert between specic video formats
at a given frequency. The available conversions also
depends on the switcher mode you are in.
• In a 3G mode, the Carbonite MultiMedia and
Carbonite+ switchers support synchronized and
unsynchronized 1080p and 1080i inputs. The 1080i
inputs are converted using a simple line-doubler
and may result in lower quality video.
• In a 3G mode, the Carbonite and Carbonite
eXtreme switchers only accept synchronized 1080p
inputs.
• In a 1080p 29.97Hz mode, the Carbonite
MultiMedia and Carbonite+ switchers support
synchronized and unsynchronized 1080p 29.97Hz
and 1080p 59.94Hz inputs. The 1080p 59.94Hz
inputs are converted by dropping half the frames
and may result in lower quality video.
