1.2.4 Audio embedder/de-embedder with audio matrix and processing
The UDC-3G-XMUX4 comes with full embedder/de-embedder capabilities. The audio
embedded on the SDI is de-embedded and can be delayed relative to the video. Each audio
stereo pair can be swapped in a matrix before being embedded back into the SDI stream.
1.2.5 Four AES I/O ports
The UDC-3G-XMUX4 comes with four bidirectional AES ports. Bidirectional means that each
port can be configured to be either an input or an output. The direction can be set
independently for each of the four ports and they will then work as inputs or outputs to the
audio matrix. The AES I/O ports are an optional feature.
1.2.6 Audio delay lines
Each AES port comes with its own delay line, which means that the audio can be given a
(positive or negative) delay relative to the video. A common delay setting is also provided for
the eight embedded channels. The delay lines make it easy to pre-compensate for the delays
incurred by external audio processors such as Dolby E.
1.2.7 Closed Caption CEA708/CEA608 and time code support
The UDC-3G-XMUX4 will transport closed caption and time code packages between input
video standard and the output video standard. In the process it will convert and transform the
packages as necessary to confirm to the output video standard.
1.2.8 Input change-over with fallback to internal generators
The UDC-3G-XMUX4 comes with an electrical SDI input and an additional (optional) optical
input. Sophisticated input selection logic can switch between the physical input when a signal
is available, and also switch to one of several internal video generators in the event that no
physical input is present.
1.2.9 Multiple SDI outputs
The UDC-3G-XMUX4 comes with four BNC SDI outputs organized as two pairs of
inverting/non-inverting outputs. Each pair of outputs can be taken from the processed video
output, or directly from the input (reclocked only) for monitoring purposes.
1.2.10 In-monitor label inserter
The UDC-3G-XMUX4 comes with a built-in label-inserter that can be used to add a
identifying text string in active video, either permanently or only when the module has lost its
expected input and has reverted to a fallback generator.
1.2.11 Long-haul optical input
The UDC-3G-XMUX4 can be equipped with an optional 9/125µm single mode optical input
for long-haul applications.
1.2.12 Video processing
The UDC-3G-XMUX4 comes with luma/chroma gain and level adjustment and spatial low-
pass filters. The low-pass filters can be a useful tool to control the bandwidth of the input to
video compression equipment.
1.2.13 EDH processing
The UDC-3G-XMUX4 always does EDH processing.
