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

audio outputs.
1.2. Features
• Embedded audio processor for 3G/HD/SD-SDI digital video signals.
• Provides:
- One 3G/HD/SD-SDI program input.
- One 3G/HD/SD-SDI auxiliary input.
-One 3G/HD/SD-SDI program output with post-processed audio distributed to two
connectors.
- Two AES/EBU digital audio inputs.
- Two AES/EBU digital audio outputs.
- Four analog audio output channels.
- One analog reference input with loop-through.
•Allows routing of any channel from the following in the embedded audio channels of
the output video, in the AES/EBU digital audio outputs and in the analog audio outputs:
- The embedded audio in the program input signal.
-The embedded audio in the auxiliary input, even if this input is not synchronized to
the program input (up to four channels).
- The AES/EBU digital audio inputs including asynchronous signals.
• Full scale level adjustment between +15 and +22dB in 1dB steps.
• Provides an audio processor at the output capable of:
- Adjusting signal level.
- Reversing the phase.
- Channel summing of a stereo pair to generate a monaural signal.
- Delaying the signal by up to 10 s.
• Can operate in sync with the analog reference or with the digital input signal itself.
•Allows generation of the Greenwich Time Signal (GTS), popularly known as "pips",
triggered by the VITC video signal. Frequency and timing for the pips are
user-selectable.
• Provides 16 presets for storage of module configuration.
•Module control and supervision can be done remotely when the mounting frame is
equipped with a communications controller module.
