Chapter 1: Introduction
Overview
The 3G-AM is a triple rate 8 channel AES audio embedder/disembedder. AES audio can
be embedded and disembedded simultaneously. The embedder is user selectable, on a
channel pair basis, to either “pass” existing SDI input audio or embed AES input 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. Horizontal ancillary data
(HANC) packets in compliance with SMPTE 291M can also be dropped at the input.
The 3G-AM automatically detects and configures to the input video standard. 3G-SDI
formats up to and including 2048x1080p 60 YCbCr 4:2:2 are supported (see
for a complete listing). SDI video loops through the device with
minimal delay. Loop through embedded SDI audio supports up to 16 channels.
NOTE:
2048x1080p/psf 29.97 and 30 formats support a maximum of 8 channels embedded audio.
Using the MiniConfig application, you can configure data packets to be passed from the
AES inputs to embedded ancillary packets un-altered. This, along with minimized
embed/disembed latency, ensures 100 percent compatibility with Dolby® bitstreams.
