Audio Processor Description

1-12
Ancillary Data Processor
This function provides full VANC/HANC ancillary data de-embedding and
embedding for 3G/HD/SD-SDI streams. Direct access to DID and SDID
locations allows extraction or insertion of user data such as camera PTZ,
SCTE 104, closed-captioning read/insert, GPI/GPO via ANC, or other
specialized user payloads. Data can be extracted and inserted within the
device (Bridge mode), or inserted and/or extracted to and from the device via
serial or IP interfaces connecting to external devices/systems. A rear I/O
module with a dedicated IP port can be used with the ancillary data processor
function for data insertion or extraction via IP.
This option also provides SMPTE 337 embed/de-embed, which allows serial
user data to be embedded and de-embedded over unused embedded audio
pairs.
Video Output Crosspoint
A four-output video matrix crosspoint allows independently applying the
device processed video output, reclocked input, or wings/key-fill previews to
any of the four discrete coaxial outputs (
output, a CVBS coaxial output is available as a processed video output. An

The audio processor operates as an internal audio router. This function
chooses from the following inputs:
16 channels of embedded audio from the SDI video input (default
•
1-to-1 routing to SDI output)
Up to 16 channels (8 pairs) of discrete AES input
•
Up to 4 channels of balanced analog audio input
•
(See Figure 1-4.) The audio processing subsection is built around an internal
16-channel audio bus. This 16-channel bus receives inputs from an input
routing crosspoint that routes de-embedded, and discrete AES and analog
audio inputs, over the 16-channel bus. Correspondingly, at the output end of
the 16-channel bus is an output routing crosspoint that in turn distributes the
16-channel bus signals to embedded, and discrete AES and analog audio
outputs.
1. Discrete audio I/O channel count is dependent on model. Current models may not support maximum
number of available discrete channels.
