I/O, Clocking and Reference
SDI I/O
ARC can access any of the eight audio pairs carried on an incoming HD- or SD-SDI stream and provide de-embedding and pair
shuffling at its input.
Note:
ARC will not generate SDI video signals, so in order for the unit to output an SDI signal, it must receive one.
An SDI video delay is provided to compensate for the latency incurred by the audio processing within ARC and to ensure proper
A/V sync at the embedded output. Detailed latency measurements are provided in Chapter 6.
ARC can simply pass through unprocessed audio from the input and/or route loudness controlled (processed) audio for two
program sources to the embedded SDI output. The output channel mapping can mirror the input channels or be pair shuffled as
needed.
AES-3 I/O
Audio received via the AES-3 input can be processed and sent to the AES-3 output, routed to the embedded SDI output, or sent
to the AES67 output.
AES67 I/O
Any visible and accessible AES67 networked audio source can be processed by ARC and returned to the network via AES67,
embedded into the SDI output, and/or sent to the AES-3 output.
Mixing and Matching Inputs and Outputs
It is possible to mix and match input sources and route the processed audio from those sources to the same or different outputs.
For example, both program sources may come in as SDI and be re-embedded to SDI. Or, one source may arrive via SDI and the
other via AES-3 or AES67, then be embedded to the SDI output or sent back to the network as AES67 audio.
