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 unit
(Bridge mode), or inserted and/or extracted to and from the unit 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.
Video Output Crosspoint
Used in common as a routing source for both
Path 1
/
Path 2
is a four-output
video matrix crosspoint that allows independently applying the unit processed
video output, reclocked input, or wings/key-fill previews to any of the four
discrete coaxial outputs (
SDI OUT 1
thru
SDI OUT 4
). For an SD output, a
CVBS coaxial output is available as a processed video output.
Audio Processor Description
Note:
Path 1 and Path 2 have individual independent digital audio embed and
de-embed banks for each of the processing path’s 16-channels of embedded
audio. The unit’s 16 channels of AES embed/de-embed can be allocated indi-
vidually to any or either path’s embed or de-embed nodes. Similarly,
four-channel analog audio can be individually allocated across any or either
path’s embed or de-embed nodes.
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
1
•
Up to 4 channels of balanced analog audio input
(See Figure 1-3.) The audio processing subsection is built around the card’s
two internal 16-channel audio buses (Path 1 and Path 2). Each 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 card bus.
Correspondingly, at the output end of each 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.
