Chapter 1: 3GM – 3G/1.5G HD-SDI Multiplexer

Overview

The 3GM is a versatile and economical tool for interconnecting dual-link 1.5G
SMPTE372M and 3G SMPTE425M. 3GM is bi-directional, allowing dual 1.5G to 3G or 3G to
dual 1.5G conversion. Additionally, 3GM’s 3G HD-SDI output is configurable for
SMPTE425M type A or B. The 3GM can even convert 3G from/to type A or B. 3GM also
provides a monitor output which is a single link SMPTE292M 1.5G HD-SDI. The 3GM is
compatible with SMPTE259M 270Mb SDI.

Features • Compact 3G to/from 1.5G conversion

• SMPTE425M-AB inputs, 3G outputs configurable to A or B

•Converts SMPTE425M A to/from SMPTE425M B

• Provides SMPTE292 monitor output for dual 1.5G or 3G inputs

• Fully equalizing and re-clocking with jitter attenuation

• Passes all ancillary data

NOTE: The Lock LED indicates valid input video by color. Green is SD video, red is HD/Dual Link

video, amber is 3G video, off is no input.

DIP Switches

OFF ON

User Controls

The user interface for the 3GM is an 8-position DIP switch accessible through a cut-out in
the bottom of the unit.

Table 1. 3GM DIP Switch Settings

Switch FUNCTION LEFT RIGHT

1 MODE:

Multiplex
or DA

2 OUT MAP:

3G A or 3G B
output map
(when set to
output 3G)

3 INPUT:

Input signal
color space:
YCbCr/RGB

MUX:
Converts between Dual-link (SMPTE 372M) and
3G (SMPTE 425M).

A Dual-Link input results in a 3G output (mode
A or B).

A 3G-SDI input (mode A or B) results in a Dual­Link output

Note: In both cases, the monitor output for a 3G or Dual-Link input will be a downconverted HD
(SMPTE 292M compliant) output.
Note: In both cases, if a single HD or SD SDI signal is fed to the Link A input connector, 3GM
enters DA mode and routes that SDI input signal to all three output connectors.

B:

Selects 3G B output mapping.
3G output is set to the B mapping structure.

YCbrCr:
If Dipswitch 8 is set to Manual or there is no
payload ID, the 3GM will behave as if the input
video is in the YC color space.

Note: In both cases, if payload ID is present and Dipswitch 8 is set to Auto, the 3GM uses the
video specifications in the payload ID.

DA:
Places device in distribution amplifier mode.

A Dual-Link input results in a Dual-Link output

A 3G-SDI input results in a 3G output
(either in mode A or B).

A:

Selects 3G A output mapping.
3G output is set to the A mapping structure.

RGB:
If Dipswitch 8 is set to Manual or there is no
payload ID, the 3GM will behave as if the input
video is in the RGB color space.

4 INPUT:

3GM v1.5 www.aja.com

Input signal
bit depth:
10 or 12-bit

10-Bit:
If Dipswitch 8 is set to Manual or there is no
payload ID, the 3GM will behave as if the input
video is 10-bit.

NOTE: In both cases if payload ID is present and Dipswitch 8 is set to Auto, the 3GM uses the
video specifications in the payload ID.

12-Bit:
If Dipswitch 8 is set to Manual or there is no
payload ID, the 3GM will behave as if the input
video is 12-bit.

5 MON TYPE:

Linear or
log color

6 MON RNG:

SMPTE or
Full range
color values

7 MON SEL:

Video or Key
for Monitor
output

LIN:
Configure input video as linear color.
Will colorspace convert and resample as
needed.

Note: Switches 5, 6, and 7 only affect the monitor output. This switch has no effect on the
primary outputs.

SMPTE:
Defines input video as SMPTE color range
(040h-3ACh).

Note: Switches 5, 6, and 7 only affect the monitor output. This switch has no effect on the
primary outputs.

VID/A:
For video input with an Alpha channel, this
sets the monitor output to Video in the case of
4:4:4:4 video input.

For video input without an Alpha channel, this
sets the monitor output to be Link A.

Note: Switches 5, 6, and 7 only affect the monitor output. This switch has no effect on the
primary outputs.

LOG:
Configure input video as logarithmic color.
Will perform a 10-bit Cineon to 8-bit linear
conversion before colorspace converting and
resampling the monitor output.

FULL:
Defines input video as FULL color range (004h­3FBh).

KEY/B:
For video input with an Alpha channel, this sets
monitor output to the Alpha (key) in the case of
4:4:4:4 video input.

For video input without an Alpha channel, this
sets the monitor output to be Link B.

8 INP MODE:

Automatic
or Manual
Setup

Installation

AUTO:
If payload ID is present, the 3GM uses data
from the payload ID information to set color
space and bit depth (switches 3 and 4).

If payload ID is not present, the 3GM reverts to
switches 3 and 4 for input information.

In normal operation the 3GM uses between 4 and 6 watts of power. Because it is
designed to use the outer case and the attached cables for heat dissipation, the case can
feel warm to the touch. This is normal. Although the 3GM has been tested for proper
operation in an ambient temperature up to 45 degrees Celsius (113 F), it is recommended
to not position the 3GM in close proximity to other warm surfaces or airflow.

To install, connect BNC cables to the desired source and destination devices and apply
power to the converter (AJA power supply included).

MAN:
The 3GM uses switches 3 and 4 for color space
and bit depth, regardless of whether payload
ID is present or not.
