HAM3000C03

1. DESCRIPTION

1.1. The HAM3000C03

The HAM3000C03 is a audio processing module that embeds asynchronous audio in the
SDI video signal. The asynchronous audio channels can come from balanced digital audio
AES/EBU input pairs or from another asynchronous video SDI signal with respect to the
SDI signal program video; in order to embed them it is necessary to resynchronize,
performing a conversion of the sampling frequency. In addition, the device also works as
a deembedder, allowing access to any of the audio channels present at the inputs in the
analog audio and/or AES/EBU digital audio output interfaces.

The HAM3000C03 module provides a 3G/HD/SD-SDI program video input (PGM IN), an
auxiliary 3G/HD/SD-SDI video input (AUX IN), a 3G/HD/SD-SDI program video output
(OUT) with video information from the program input, a loop-through analog reference
input (SYNC-LOOP), two AES/EBU balanced digital audio input pairs (AES1 IN y AES2 IN),
two AES/EBU balanced digital audio pairs (AES1 OUT y AES2 OUT) and two analog audio
output pairs (ANALOG1L/R OUT y ANALOG2L/R OUT).

In addition to embedding, deembedding and sample rate conversion, the HAM3000C03
can reassign input signal audio channels to any of the output signal audio channels and
adjust the gain applied to each of them independently. It is also possible to implement a
delay of up to 10 s in each audio channel.

The HAM3000C03 module can operate as a frame synchronizer or delayer. The output
video signal OUT can be synchronized to either the analog reference input or to the
program video input signal.

It is possible to monitor the HAM3000C03 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 HAM3000C03 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.

The HAM3000 is a family of several audio processors. The variations within the family
are as follows:

• HAM3000C01: Modifier for audio embedded in 3G/HD/SD-SDI digital video.

• HAM3000C02: Modifier for audio embedded in 3G/HD/SD-SDI digital video with analog

audio inputs.

• HAM3000C03: Modifier for audio embedded in 3G/HD/SD-SDI digital video with analog
