functional description
The C8651 allows to receive and transmit asynchronous Dolby metadata (RDD6) via serial RS485
interface. The metadata received will be inserted into a pre selected audio data bus for reception by
any module within a c8k frame. This proprietary metadata transport mechanism is very flexible
and powerful for metadata exchange and management.
Since Junger Audio is using the AES User Bits for transportation, this method is compatible with all kind of
AES/EBU related audio transport interfaces like AES3, AES3id, MADI and SDI embedded audio.
If one connects such an audio bus to a C8188/89 AES output you will be able to move the metadata
alongside with discreet audio.
The C8651 will also extract metadata from a c8k audio bus and will move it to the asynchronous serial
RS485 output connector. The source of such metadata can be any kind of module inside a c8k frame
(e.g. the VANC Dolby metadata de-embedder).
