Vertigo XG
Installation and Quick Start Guide
Audio Input/Output Channels
The Vertigo XG supports both embedded and discrete audio channels. Each video
input/output can contain up to 8 stereo pairs (16 channels) of embedded audio.
The number of discrete audio input/output channels depends on the number of physical
inputs available. For each physical input available there will be a discrete audio breakout
cable. Each discrete audio breakout cable contains 4 BNC inputs and 8 BNC outputs. Each
BNC connector represents 1 stereo pair (2 channels) of digital AES/EBU audio. Therefore,
each discrete audio breakout cable contains 4 stereo pairs (8 channels) of input and 8
stereo pairs (16 channels) of output.
When capturing audio, the Vertigo XG can capture embedded and discrete simultaneously,
however there are restrictions. The stereo pair cannot be captured from both sources at the
same time. For example, if only capturing pairs 1 & 2 from embedded, then pairs 1 & 2 are
not available from AES, but 3-8 are available.
The Vertigo XG performs one-to-one passthrough of audio. All captured audio will be
broadcast on the corresponding outputs. For example, if the first 2 stereo pairs of
embedded audio on SDI IN A are captured, then the signal will be output as the first 2
stereo pairs of embedded audio on SDI OUT A and simultaneously on AES discrete outputs
1 & 2.
Ancillary Data Processing
The Vertigo XG reserves some hardware functionality for the extraction, processing, and
insertion of ancillary data into the output video signal, for example, Vertical Ancillary (VAnc)
data and Vertical Blanking Interval (VBI) data.
The ancillary data space can be used as a transport mechanism for data to be extracted by
the Vertigo XG for triggering keyers, squeezes (DVEs) or other graphics events. Metadata
embedded upstream of the Vertigo XG is extracted and processed by the control
application to control these actions.
