3.4 Theory of Operation
The M2D Decoder includes both DVB-ASI and Ethernet ports (refer to figure 1 block diagram
below). The system also offers a choice of transport protocols with support for AVC embedded
within a MPEG-2 TS (ASI input or over IP**) and raw H.264 bit streams. Both transport mechanisms
can be delivered over UDP** and RTP/UDP**. A compressed stream can be input from the DVB-ASI
interface, and reformatted for IP Streaming** and output at the same time that it is being locally
decoded.

Control & Status
Figure 1 Block Diagram
The Decoder can be set to tune both video and audio in two ways: Auto or Manual. In Auto
mode the unit will self acquire the first MPEG program in the transport stream and decode the first
audio & video PID listed in the PMT for that Program.
In Manual mode the program number can be selected when Multi Program Transport Streams
(MPTS) are present. Within the selected MPEG program, each of the two** audio processors can
have an audio PID from that program selected.
The M2D can be controlled through its front-panel control interface. Additionally, it has two LED
status lights. The green “Lock” LED notifies user that the M2D has a valid ASI stream and is able to
decode the Transport Steam. The second red LED status light is for “Error” conditions.
The Decoder incorporates error resiliency features. In the event of damaged bit-stream the
Decoder can replace the corrupt slice with skips and resume decoding at the next NAL (Network
Abstraction Layer) unit. Alternatively it can freeze the output until a new I-frame is received.

3.5 Normal or Ultra-Low Latency Modes
All GMS Messenger products include two operating modes that relate to system latency. In
“Normal” latency mode GMS offers full compatibility with conventional digital video products. In
this mode, delay will be equivalent to the normal delay found in commercial equipment (250msec
to 500msec, decoder dependant).
The Ultra-low latency mode provides an incredibly low system latency of down to ~44msec plus“
propagation time! This unique capability provides the fastest response times to time critical
situations. The main contributor to normal operating mode latency is the size of the “I” or IntraRefresh frame and the time it takes for this to travel through the wireless link. The ‘I’ frame is
normally 5-7 times larger than the “P” or Progressive frames. In Ultra-low latency mode we perform
a non-conventional compression operation. We break-up the I-frame and send it in pieces along
with multiple P-frames. This tends to level or smooth the data throughput through our Constant Bit
Rate (CBR) wireless link. This allows the latency to be dramatically reduced!
.
This non-conventional operating mode is part of the MPEG standard. However, it is not universally
supported by all commercial vendors because many applications do not need to deal with its
complexity.
4. Initial Check Out
Prior to installing a M2D unit into the desired target environment, an initial checkout should be
performed to ensure proper operation of the unit. The initial checkout consists of taking an ASI
source and feeding it into the ASI IN of the M2D and ensuring video and audio are decoded.
The M2D is pretty much a ‘plug & play’ unit and thus is ready to work “right out of the box”.
Just supply a power source and power cable along with an ASI stream, switch on the unit and it will
start to decode without any input from the user.
The following power supply and power cable are available from the factory as follows:
780-C0485 Cable, M2D Mic Conn Pigtail
473-064-G Power Supply with Mic Connector
If a +12Vdc source is already available with the proper current handling capability (see
specifications under section 9) then only a pigtail cable with the proper connector needs to be
ordered.
780-C0484 Cable
The basic setup is shown in Figure 2 below.

Figure 2 Check Out
Provide power to the M2D by attaching GMS # 473-064-G pigtail mic connector to the M2D
“DC PWR” connector and to GMS power supply 780-C0485. Plug the supply into a wall
socket.
Note: If using an off the shelf power supply ensure it can source at least 1.5A at
+12VDC and use GMS pigtail cable # 780-C0484 to attach to the M2D.
Attach a known good ASI stream (DVB compliant) into the ASI IN connector of the M2D.
Attach video cables from the video outputs to a monitor.
Attach audio cables from the audio XLR connectors to speakers.
Power on the M2D by toggling the “PWR” switch on the front panel to up position. The two
LEDs on the front panel momentarily turn on & off. After a few seconds the front panel LCD
lights and displays the “AVC Messenger 2 Decoder” logo and then displays the TS (transport
screen). It should decode the video and audio from the program on the TS. The front “LOCK”
green LED should light.
The initial checkout described above is simply to check the basic video operation of the M2D
unit.

5. Hardware Overview
5.1 Front Panel Description
Front Panel view of M2D is shown in Figure 3 below. A brief description of the LEDs, power switch,
connectors, and front panel are stated below.
Figure 3 Front Panel
5.1.1 ON/OFF Power Switch
The PWR switch is a toggle type switch, up for ON and down for OFF.
5.1.2 Local Control Panel
The Local Control Panel consists of a backlit LCD Display (dual line, 16 characters per line) and
4-button keypad, ENTR, CTRL, the up and the down arrows.
Refer to the flowcharts (see section 6).
The CTRL key allows the user to sequence through each of the available menus.
The ENTR key allows the user to enter sub-menus when available and to confirm a
selection.
The UP and DOWN arrows are for toggling through various selections when available.
5.1.3 Status Indicators
The green LOCK LED lights when the M2D receives a valid MPEG Transport Stream (TS).
The red ERROR LED lights when an error occurs in the unit:
When the unit first powers up and when there is no TS, a corrupt TS or a non-valid TS
For units with the optional Genlock :
Genlock function is enabled but the M2D can’t lock to the reference Genlock
clock.
The Genlock reference input signal does not match the video format which is
decoded.
100-M0134X1B 11 of 40
www.cobham.com/gms
Note: If the red error LED lights on the front panel and the unit has Multi-Program or
Genlock optional features installed then it’s a good idea to check the STATUS menu (see
section 6.2.2) for clues as to why the errors are occurring.
5.1.4 A/V Connectors
VID yellow RCA-F type connector is the port for Composite Video. When processing HD
AVC the composite video out is from an internal video scaler. When unable to scale the
output displays color bars.
Note: The Video Scaler does not always accurately represent the HD signal. Test
patterns with very narrow lines can be distorted by the scaler. However, it does an
acceptable job of converting normal video from a camera.
AUD 1 and AUD 2 red and white respectively are single ended audio outputs, type RCA-
F connectors. Audio levels are not adjustable from the M2D.
5.2 Rear Panel Description
Figure 4 shows the rear view of the M2D. A brief description of the connectors (type and
function) is mentioned here. Refer to the specifications section (section 9) for additional detailed
information.

5.2.2 LAN
The LAN connector is a type RJ45 Ethernet 10/100 base T. It can be used to update new
firmware versions (see section 10), streaming video (future update) and for remote
operations (future update).
5.2.3 ASI IN
The ASI IN is the input connector (BNC-F) for an ASI stream (TS input/DVB compliant)
which are to be decoded.
5.2.4 ASI OUT
The ASI OUT is a loop-through output (connector type BNC-F) of the ASI stream presented
on the ASI IN connector.
5.2.5 HD-SDI/SDI
The HD-SDI/ SDI is an output (connector type: BNC-F) which can display high definition or
standard definition through the serial digital interface (SDI).
Available as an option; audio which is decoded is automatically placed on the SDI stream
(embedded). Only two channels are available and are mapped to channel 1 and channel 2.
5.2.6 SNYC
5.2.7 Y,Pb,Pr
5.2.8 VID
The SYNC is used as an input sync source for Genlock (a BNC-F connector).
Y, Pb and Pr are the three RCA-F output connectors for analog component video. These
connectors are not color coded according to industry standards. Y carries the luma, the
brightness & sync information (colors associated with this connector are usually green or
yellow).
Pb carries the difference between blue and luma (B-Y) and Pr carries the difference between
red and luma (R-Y). Blue & red colors are associated with these connectors respectively.
The VID connector (RCA-F) is a second composite video output which essentially mirrors the
front composite video output. As mentioned above when processing HD AVC the composite
video out is from an internal video scaler. When unable to scale the output displays color
bars.
Note: The Video Scaler does not always accurately represent the HD signal. Test
patterns with very narrow lines can be distorted by the scaler. However, it does an
acceptable job of converting normal video from a camera.
100-M0134X1B 13 of 40
www.cobham.com/gms
5.2.9 DVI
The DVI (Digital Video Interface) connector (DVI-I socket-female) is an output which
provides another means of viewing the video into a monitor with a DVI connector or it can
be converted to HDMI (using a external adapter) Composite signals (NTSC & PAL) are not
available through this output.
5.2.10 MISC I/O
The MISC I/O is a specialized connector (see the specifications section 9 for details and pin
outs) which contains the signals for RS232 user data (future update), USB control (future
update) and digital audio (future update).
5.2.11 AUD 1 & AUD 2
AUD 1 and AUD 2 are XLR-M connectors providing balance audio out. Audio levels (gain)
are not adjustable from the M2D
5.2.12 RF1 & RF2
These spaces are reserved for RF inputs which are not used on the M2D.
6. Local Front Panel Display & Screens Explained
NOTE: The words display and screen are used interchangeably.
The M2D’s front panel LCD display and various screens are explained in this section.
When power is first applied the LCD backlight lights up and within 5 seconds or so the unit boots up
and displays the product type, in this case it’s a Messenger 2 AVC Decoder. The display then
changes to the MAIN menu screen. This screen as explained below gives the user a quick status of
the system. For example it shows if a TS (transport stream) is present, if audio and video are being
decoded and in addition it shows the decoded video format.
In general the CTRL button sequences through the top level menus or if in a submenu it will
traverse through each of the menu options within the submenu. The ENTR button allows the user
to enter a submenu if presented with a choice to do so and it also allows the user to confirm a
selection when more than one option is available. In some cases the ENTR button can act as a
shortcut and allows the user to jump to a setup menu. The UP and DOWN arrows allows the
user to choose between various options when presented with them. When you see the following
symbol in a screen then you have other options to select from:

6.1 Flow Chart (including the Genlock option )
This section explains the various screens available to the user. The menu structure consists of the
Main menu page, the Status menu page, the Setup menu page (which is broken down into the
Genlock and Program submenus) & the System menu page.
6.1.1 Main Menu
The M2D boots up in the MAIN menu which is shown in figure 6 below. The Main menu is
literally the status of the TS (transport stream). It shows the user at a glance if a TS is present
with a capital ‘Y’ for yes or an ‘N’ for no. It shows if a Prg (program) is present on the transport
stream with the same indicators ‘Y’ or ‘N’. It also shows if ‘Aud (audio) and VID (video) are
present. All menus returning to the MAIN menu return here.

Note: Two flowcharts are shown in figure 9 for the Genlock menu. One is when
Genlock is ON and the other is when Genlock is OFF. Also refer to section 7.0 for an
explanation of the various Genlock setup options.
The first screen presents the user with the options to turn Genlock ON, OFF or to
AUTO. If ON and there is no reference signal or incorrect reference on the SYNC input
(see section 5.2.6) the red error LED on the front panel lights. Otherwise if the reference
is correct the green LOCK LED on the front panel lights. If OFF Genlock is disabled
regardless if and what type of reference signal is on the SYNC input. . In AUTO mode
Genlock automatically locks if there is a reference signal on the SYNC in which it can
lock to.
If Genlock is ON then the Genlock offset Pixels and Genlock Offset Lines screens are
shown otherwise they are not. These screens give the user the option of adjusting the
100-M0134X1B 18 of 40
www.cobham.com/gms
Genlock signal offset in terms of pixels or lines. The total number of pixels or lines
available for adjustment is determined by the type of reference signal on the SYNC
input.
The remaining displays allow the user to either return to the MAIN menu or to the
SETUP menu.
Once Genlock has been setup it can be monitored from the STATUS menu, see section
6.2.2 (and figure 7). The STATUS menu “Genlock” screen shows if Genlock is locked, if it is
ON, OFF, or in AUTO mode, if a reference signal is present (and the format), and the output

6.1.3.2 Program Menu
The PROGRAM menu allows users to choose AUTO or MANUAL mode detection.. The
PROGRAM menus (see figure 10 below) are displayed a little differently depending on which
mode is selected. Basically if decoding a multi-program stream then MANUAL mode offers
the user the ability to choose the desired program which is to be decoded. AUTO mode is
mainly for a TS with a single program. If the TS has multi-programs and the M2D is in
AUTO mode then the first program it can detect (from the PAT table) is decoded,
The “SELECTED PRG: #” display shows which program is currently being decoded and it
cycles through the PIDs of the decoded program...
NOTE: If the M2D is power cycled and it was previously set for MANUAL program
detection it remembers the specific program number it was decoding. Hence if for some
reason that particular program number is no longer present then another program
number needs to be selected from the “MANUAL PROGRAM” display in order for
decoding to continue.

6.1.4 System Setup
The following screens are found und the System menu.
There are three firmware versions labeled DSP, Xil, and Dec. The firmware versions are
displayed in the first screen one line at a time (briefly) and the versions are continuously
cycled until the CTRL key is pressed. If updating to new code this is a good place to check
to see if the new versions are actually correct.
The next two displays, ‘Hardware Version’ and ‘Serial Number’ are self-explanatory. The
serial number should be recorded in case it’s needed when talking to customer service.
The next screen displays the model name.
The final screen gives the user the ability to get back to the Main menu.

7. GenLock (option)
Genlock is a means to ensure video signals are synchronized; this is an optional feature and is not
available on all units. The specifications for Genlock are listed in section 9, “Genlock Option”. The
Genlock input signal is attached to the SYNC BNC connector on the rear of the M2D (see rear
panel description, 5.2).
Genlock can be setup under the GENLOCK MENU (see section 6.1.3.1). This is where it can be
turned ON, OFF or to AUTO and offsets (pixels or lines) can be adjusted. Once Genlock has been
setup it can be monitored under the STATUS menu (see section 6.1.2). Under the STATUS menu
Genlock is continuously monitored and shows the reference signal format (if there is one) the
video format which is being decoded and the current mode it is set to (ON, OFF, AUTO).
A brief description of the operating modes (ON, OFF, AUTO) are described below:
ON keeps the Genlock function enabled regardless if there is a reference signal on
the SYNC input. If a TS is present the audio & video are processed with or without a
Genlock reference signal. However, extra latency is added to the decoding process
with Genlock always ON. (see specifications section 9).
AUTO mode turns the Genlock function OFF until it detects a reference signal on
the SYNC input connector. If a TS is present audio & video are processed with or
without a Genlock reference signal. If a reference signal is detected the Genlock
function is enabled. The benefit to this mode is that until a reference signal is
detected on the SYNC input the Genlock function is essentially OFF and therefore
the decoding latency is not increased.
OFF mode keeps the Genlock function disabled regardless if there is a reference
signal on the SYNC input.
In addition to the operating modes, Genlock synchronization can be adjusted with the pixels or
lines of the reference signal. The numbers of lines or pixels which are available correspond to the
reference signal video format.
8. Embedded Audio (option)
The audio on the TS which is decoded is automatically embedded into the SDI output along with
the video. Only two channels are supported and they are mapped to channel 1 and channel 2 on
the output. The sample rate supported is 48 KHz. There are no controls or selections to enable,
this is done automatically.
9. Multi Program Transport Stream
Transport Streams containing multi-programs can be decoded. Up to 16 programs can be detected
from the PAT table, all others are ignored. Users can decide which program to decode when the
decoder is set up for MANUAL under the PROGRAM menu setup (see section 6.1.3.2).
The PIDS (PCR, Video, Audio & PMT) of the current program selected are displayed under the
PROGRAM setup menu and in addition are monitored and displayed under the STATUS menu (see
the “Selected Prg: #” screen).
If running a multi-program TS and the decoder is set for AUTO (under the PROGRAM menu setup
it) will decode the first program it finds in the PAT table.
100-M0134X1B 23 of 40
www.cobham.com/gms
Note: When running in MANUAL mode the M2D decoder remembers the program number
it currently is decoding. If for some reason the program number becomes unavailable the
decoder will not continue decoding until another program number (which is available) is
selected. It will however show if a particular program number is no longer available.

The Video Scaler does not always accurately represent the HD signal. Test patterns with very
narrow lines can be distorted by the scaler. However, it does an acceptable job of converting
normal video.
11. Upgrading New Firmware Through the IP Port
This section explains how to load the M2D with new firmware releases. There can be up to three
separate firmware loads. They are usually labeled as D; X & W.
D: The LCD displays DSP code as a “D:” (this code is always updated with the “.out
file)
X: The LCD displays this FPGA code (for Xilinx) as an “X” (this code is always updated
with a “.bit
” file)
W (also noted as “DEC”): The LCD displays this FPGA code (for the Altera) as a “W” or
“DEC” (this code is always updated with an “.rbf
The correct file type (.out, .bit, or an .rbf) must be selected before programming.
Step 1:Open Microsoft Internet Explorer or Firefox and type in the IP address, see section 6
(6.1) on how to acquire the IP address from the M2D. See figure xx below. The Web
Interface opens…click on the “continue” button.

www.cobham.com/gms
Figure 11 Web Interface
Step 2: Next an “Authentication required” text box appears. Type in “admin” for User Name
and “admin” for Password.
Step 3: The main M2 AVC Decoder screen opens, see figure 13 below. Select
“System/Upgrade/DSP Firmware“(or the corresponding firmware which needs to be
100-M0134X1B 30 of 40

loaded….Xilinx or Altera). This example deals with the DSP upgrade, however all upgrades
are very similar.
NOTE: If a firmware upgrade is necessary customer service notifies the end user as to
which firmware load is necessary and sends the link to the FTP site where the correct file
can be downloaded.
Figure 13 Main Screen
Step 4: The “Browse” for file screen opens. See Figure 14. Scroll down to the bottom of
the screen and click on the “Browse” button to browse for the correct file. Remember in this
example the DSP firmware is being updated so the “.out” file is the correct file to use. Also in
this example the DSP presents a checkbox choice for the “Program Number”; 1 for
“(factory)” or 2 for “(field upgrade”.) The “field upgrade” checkbox should be selected.
What this ensures is that the new firmware will be loaded from location 2. If for some reason
the new load is corrupted (or does not load correctly) the M2D will fall back to the firmware
in location 1 (the firmware which was running before the upgrade). Also it is not necessary to
check the “Update Boot Loader”. This is done during the initial programming of the flash at
the factory.

Figure 14 Browse for File
Step 5: After browsing for the correct file and it’s been placed into the “File Name” text box,
click on the “Upload File and Program Flash” button. The “Progress” screen appears (see figure 15
below). Wait until the programming is complete before removing power or taking any other
action.

Figure 15 Progress Screen
Step 6: After the file has been written into Flash an update status screen appears (see figure 16)
notifying the user that the file was successfully written into Flash (or not). To run the new code
the M2D must be re-powered. The new version (s) should also show up under the “Version” LCD
screen (see section 6.22 & 6.1).

NOTE… Although the example above deals with uploading new code for the DSP the
procedure is almost exactly the same for loading new FPGA (Xilinx or Altera) code. The only
difference is the “Browse” screen. There are no check boxes to worry about (see figure 17
below)

If TS = Y, PRG = Y but VID = N then chances
are the video source into the transmitter has

Ensure it is enabled at the transmitter end.
Volume level is not adjusted from the M2D.
Ensure the volume level is sufficient for it to be
hear (either at the transmitter end or an external
amplifier).
