The DAI-3206 is a high performance audio embedder for 270 Mbit SDI video signals. It supersedes the earlier DAI-3200 audio embedder.
Existing embedded data packets may be optionally
removed and/or replaced via link settings on the PCB.
Each DAI-3206 is capable of inserting one audio group (2 AES signals, 4 analogue channels or combination of AES and analogue pair channels) into an existing SDI video stream. Group position selection is made by the front panel local control.
Note that when inserting 2 AES streams, both
channels must be frequency locked to each other.
Analogue audio is automatically locked to the other
AES signal, if present, or else to the SDI video input. |
The DAI-3206 supports AES/EBU synchronous/
asynchronous 48 kHz, 20-bit audio data packets.
An audio presence indicator is provided for each
input. If one AES or analogue audio pair is missing
then those particular channels are set to zero. If both
AES and/or analogue audio pairs are missing
(dependent on mode selected), then no packets are
inserted.
The DAI-3206 complements the DAX-3206 audio
extractor.
The DAI-3206 is fabricated in IRT's standard
Eurocard format and may be housed in a variety of
IRT Eurocard frames alongside other standard
modules. |
