HD10AM

AJA HD10am AES Audio Embedder/Disembedder

The AJA 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 DIP switch 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 DIP switch 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 DIP switch.

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.
