1. DESCRIPTION
1.1. The DEM3000C01
The DEM3000C01 module is a embedder of AES/EBU-format digital audio
AES/EBU-format digital audio into SDI video signals as per SMPTE 272M-AC. The
DEM3000C01 consists of two identical sections that can insert two streams of digital
audio, the equivalent of four channels of analog audio, into each SDI video signal. The
audio to be embedded must have a sampling frequency of 48kHz and be synchronized
to the video. The module includes digital audio reference outputs as per AES11 that are
generated from the input SDI video and can be used to synchronize other sources of
digital audio when needed.
The DEM3000C01 operates with binary encoded video at 270 and 360Mbit/s for both
525 and 625 line systems.
The module provides a pushbutton and various LEDs on the front panel in order to select
and indicate into which group the audio will be embedded. This and other operations
can also be performed remotely by installing a communications controller in the same
mounting frame as the DEM3000C01.
The reserved fields of the SDI stream for (EDH) error detection are both processed and
updated completely.
It is possible to monitor the DEM3000C01 status remotely using a communications
controller module installed in the same mounting frame. In addition, certain controller
modules provide SNMP management and the ability to record events in a file including
date and time information for further analysis.
The DEM3000C01 is a TL3000 terminal line module and can be housed in a three rack
unit (3 RU) UR3000 mounting frame or a 1 RU UR3100 mounting frame.
