Introduction

AJA HD10AM HD/SD 8-Ch AES Embedder/Disembedder User Manual — Introduction

The HD10AM is a dual rate 8 channel AES audio Embedder/Disembedder. The
Disembedder is always functional, outputting group 1 and 2—or 3 and 4 (user
selectable) when present on the input SDI. This is independent of the embedding
process. The Embedder is user selectable, on a channel pair basis, to either “pass” SDI
input audio or embed input AES audio from the breakout cable. The ability to pass
incoming ancillary data makes it possible to embed up to 16 channels of audio by
cascading two units: the first embedding to groups 1/2, and the second embedding to
groups 3/4—or vice versa. It also means that any ancillary data packets in compliance
with SMPTE 291M will be passed through as-is.

With the SRC dipswitch setting ON, AES inputs are sample rate converted to a
48KHz rate synchronous to the video input.

The HD10AM automatically detects and configures to the input video standard. The

Lock LED glows red for HD and green for SD formats.

With the SRC dipswitch setting OFF, data packets are passed from the AES inputs to
embedded ancillary packets un-altered. This is done according to SMPTE 337M.
48KHz synchronous ancillary packets are disembedded and passed unaltered to the
AES outputs regardless of the position of the SRC dipswitch.

All AES3-2003 defined channel status bits are passed through unaltered in both the
embed and dis-embed directions—except for the sample rate field, which is always
set to 48KHz. The channel status CRC is re-calculated and inserted into the
bitstream. This ability, along with a very small audio embed/disembed latency,
ensures 100 percent compatibility with Dolby® bitstreams.
