1.1 The core functionality
The UDC-3G-XMUX4 is a format and standard converter that can convert between all the
common SD, HD and 3G level A video standards. As part of the conversion, the aspect ratio,
the crop, or the position of the output picture can also be altered. This process can be fully
automated by AFD, WSS, WSS-EXT, or VI in combination with 12 built-in conversions, or the
user can take full manual control by selecting between 12 built-in conversions and 12 fully
configurable custom conversions.
Motion adaptive de-interlacing is used to ensure optimal picture quality.
The UDC-3G-XMUX4 comes in the standard Flashlink form factor and it is designed to be
used with Multicon Gyda, the Nevion system controller. A subset of the configuration
parameters can also be controlled by onboard switches, enabling stand-alone operation.
1.2 Secondary functionality
1.2.1 Standard conversion
The UDC-3G-XMUX4 can be used for standard conversion, i.e. conversion between 50 Hz
and 60 Hz / 59.94 Hz time bases. The motion adaptive de-interlacing ensures a remarkably
artefact-free output for this class of converter.
1.2.2 Frame synchronizer
The UDC-3G-XMUX4 has a built-in frame synchronizer. It can synchronize the SDI output to
a traditional black & burst reference or to a tri-level sync reference. The SDI output can be
phase adjusted relative to the sync signal. No additional frame delay is available for the
UDC-3G-XMUX4.
1.2.3 De-glitcher
The UDC-3G-XMUX4 comes with a built-in de-glitcher for continuous and seamless output.
This will clean up line errors due to up-stream switching or other signal glitches. The output
even remains error-free with change of input formats.
