Introduction
Thank you for your interest in Dune HD Network—a flexible and powerful Full HD
Digital Signage solution, which allows automated demonstration of a wide range
of HD video materials (up to 1080p, including H.264) on monitors, television sets,
etc.
The solution includes support for scrolling text and graphic logos over video,
which is typically required in public places for commercial and announcements.
System Components
∙Presenter—an HD video playback device (player).
◦Is connected to a display (TV, monitor, etc.) or a number of displays via
HDMI splitter(s).
◦Contains a hard drive with video clips, scrolling text, graphic logos and the
playlist.
◦May be connected to a network (LAN). This makes the HDD available via FTP
to update the playlist.
∙Control Center—a PC application to control the Presenters on a network.
◦Offers to edit the playlist, download video clips to a Presenter.
◦Allows to view/change the configuration of a Presenter.
◦Shows the status of a Presenter, allows to restart it, etc.
◦Works on any platform—Windows®, MacOS®, Linux, etc. (based on the Java™
technology).
A typical installation of Dune HD Network consists of a number of video playback
devices, each connected to a display (or a series of displays via HDMI splitters),
and optionally to a Local Area Network (LAN). Such playback devices are called
Presenters in the scope of Dune HD Network.
Most of the HD video players manufactured under the Dune HD® brand are
capable of working as Presenters—the firmware of the players has a special Digital
Signage mode.
Note: The Digital Signage mode of a player is an optionally licensed
functionality. It is available only if the player license includes “HDNetwork”
option; this can be checked in the player menu Setup > Information. If the

© 2013 Dune HD. All rights reserved. 5
“HDNetwork” option is purchased, all the basic player functionality remains
available.
Each Presenter plays video files which are located on its local storage—a built-in
HDD or a connected USB drive (for clarity, in this manual such local storage is
always referred to as HDD). The configuration of a Presenter (the playlist, scrolling
text and other options) is also stored there.
If the Presenters are connected to a LAN, they may be configured to show the
same sequence of video clips synchronously. Also, the Control Center application
is offered to remotely control them from a PC connected to the same LAN—
transfer video files, edit configuration, restart Presenters, etc.
The Dune HD® brand is constantly improving its products, and may provide
firmware updates, which may extend the capabilities of Dune HD Network.
Capabilities
∙Playing the programmed sequence of video clips and static images.
∙Support for Full HD 1080p (1920×1080 Progressive) playback.
∙Support for most advanced video codecs (including H.264).
∙Showing text messages in the form of a scrolling text line over the video.
∙Showing graphic logos over the video clips and/or static images.
∙Possibility to automatically enter the Digital Signage mode after power on.
∙Working using a defined schedule.
◦Using different configurations (playlists) in different time intervals.
◦Turning the Presenter on and off according to the schedule.
◦Flexible capabilities of schedule configuration (including the possibility to
specify an individual schedule for each day of week).
∙Possibility for multiple Presenters in the same network to display video clips
synchronously.
∙Configuring all parameters via a locally stored configuration file which is
available on the network for reading and writing via the FTP protocol.
∙Control Center PC application for centralized remote control of the Presenters
on a network.
◦Support for controlling multiple players and groups of players.
◦Convenient user interface for players configuration.
Note: In future versions of the firmware, the capabilities may be changed or
extended.

Supported Media Formats
In the Digital Signage mode, the following file formats and codecs are supported:
∙Video files: TS, M2TS, MPG, VOB, AVI, MOV, MP4, QT, ASF, WMV.
∙Video codecs: MPEG-2, MPEG-4, DivX, Xvid, WMV9, VC1, H.264.
∙Audio codecs: AC3 (DD), EAC3 (DD+), DTS, MPEG 1 layer 1/2/3, AAC, LPCM,
WMA, WMAPro.
∙Image files: JPEG, PNG, BMP.
Notes:
1. Some variations of these file formats are not supported.
2. In some hardware models, DTS decoding is not supported.
3. The set of supported file formats may differ from the one of the basic
player mode. In particular, the MKV format is not supported in the Digital
Signage mode.
4. In future versions of the firmware, more media formats may be supported.

Automated Playback
When a Presenter enters the Digital Signage mode, it starts performing the
automated playback according to its configuration which is stored in the
configuration file on the local HDD. The configuration, among other options,
defines a playlist and optionally a schedule which may assign different
configurations for different time periods.
Playback Routine
The automated playback in the Digital Signage mode involves three independent
displaying activities which work in parallel:
∙Playlist playback—video clips and/or static images.
∙Scrolling text—running text line over the video.
∙Graphic logos—images shown over the video one after another for a specified
time periods.
Each of these activities is performed according to its own configuration options or
not performed at all (if demanded by a configuration).
Playlist Playback
Playlist consists of a number of video clips and/or static images. The items on a
playlist are shown sequentially, and the playlist is cycled—after the last item is
shown, the playback continues with the first one.
Note: Please do not confuse the static images shown on a playlist with graphic
logos—the latter are shown by a completely different mechanism.
Each video clip is shown to its end, unless some IR remote control buttons are
used.
All static images on a playlist are shown either for a fixed period of time or for an
unlimited time, according to the respective configuration option. In case of
unlimited time, the playlist item may be changed manually with an IR remote (if
the buttons are not locked), or when the schedule demands configuration change.

8 © 2013 Dune HD. All rights reserved.
Note: In case the synchronized playback for multiple devices is configured (see
a dedicated section of this manual), a black screen may be shown at the
beginning of each clip for a necessary time period.
Scrolling Text
The configuration of scrolling text specifies a list of messages and a number of
options.
The messages from the list are concatenated to form a single text (possibly long).
It may be configured to insert an arbitrary separator between messages. This text
is shown in a form of a scrolling text line. The location and colors of the text line
are defined by configuration options.
The text is shown in a cycle. The configuration defines one of the two ways to loop
the message list:
∙Presenter waits for the end of the last message to scroll out of the screen, then
after the specified number of seconds the first message appears.
∙The first message of the text is shown concatenated to the last one (using the
separator if configured).
Graphic Logos
The configuration allows to specify one or two graphic logos. The logos are shown
one after another in a cycle as follows.
1. Show the first logo for the specified period.
2. Hide the first logo and wait for the specified period.
3. If only one logo is defined, go to step 1.
4. Show the second logo for the specified period.
5. Hide the second logo and wait for the specified period.
6. Go to step 1.
Note: When a Presenter enters the Digital Signage mode, the logo cycle is not
guaranteed to start from the step 1. It may start at any time point inside the
cycle, even not necessarily from the beginning of some step.
The screen location for each logo may be configured, and some randomization of
the placement is supported which may be helpful to prevent screen wearing for
certain display types.

© 2013 Dune HD. All rights reserved. 9
Attention: It is the responsibility of the configuration author to assure that the
graphic logos will never intersect with the scrolling text line. Otherwise, visual
artefacts may occur.
Updating Configuration File
The configuration file may be updated any time via FTP (as the Control Center
application does) and SMB. However, it is reread by the Presenter only on certain
moments described below, and different groups of options are put into effect at
different moments.
Message list (scrolling text) and graphic logos changes, including switching to a
new configuration according to schedule, and related options, are put into effect
when the last message of the list is shown and scrolls out of the screen.
Other options, including video playlist changes and its switching to a new
configuration and going on/off according to schedule, come into effect after the
current video clip finishes. If the current position in the playlist is a static image,
these settings come into effect immediately, without waiting for the configured
image delay time.
Synchronized Playback
By default, each Presenter plays the video clips and/or static images independently
from other Presenters. However, if the configuration specifies the synchronized
playback mode, then before starting to play next clip/image, all devices which
belong to the same group (see below) will wait until the last device finishes
showing the previous clip/image.
Note: Synchronized playback may be unsupported for certain player models.
If the wait period exceeds the value specified in the configuration, a technical
information about the synchronization mode will appear on screens.
Note: The synchronization does not influence scrolling text and graphic
logos—these activities are independent from the playlist playback and are not
synchronized.
To assign a certain group to a Presenter, the group name should be specified in
the Presenter’s configuration. All Presenters which have the same group name are
considered to be members of that group. Presenters which have an empty group
name are considered to belong to the same group with an empty name.

10 © 2013 Dune HD. All rights reserved.
Attention: All devices in the same group should have identical synchronization
settings, schedule, playlist, and contents of files on the playlist. It is
recommended that all devices have identical configuration files. For
conveniency, the Control Center application allows to save the configuration to
all devices in a group, see corresponding section in this manual.
The changes of the synchronization options take effect only on entering the
Digital Signage mode. After any changes of the synchronized devices
configuration, it is recommended to simultaneously restart them using the
corresponding remote command, e.g. choosing Restart Selected Devices task in
the Control Center application for all Presenters in a group.
There are two modes of synchronization—server-based (recommended) and
serverless (special).
Server-Based Mode (Recommended)
In the server-based mode, one of the Presenters in each group is configured to act
as a server, and all other Presenters of that group are made aware of its IP
address.
During the first synchronization phase (before playing the first item in the
playlist), the server waits for the specified period of time for other Presenters to
announce their presence. During the subsequent phases it waits until all the
devices discovered at the first phase are reported to be ready.
If a Presenter does not respond on some non-first phase for the configured period
of time, it is temporary excluded till the next synchronization phase, and other
devices start the phase synchronously. Thus, temporary loss of network or power
by some devices does not lead to the broken synchronization.
Serverless Mode (Special)
In the serverless mode, during each synchronization phase (before playing next
item in a playlist) each Presenter in a group waits for all other Presenters in that
group to report being ready for playback.
This is achieved by broadcasting the synchronization messages to all devices that
are connected to a single network. Thus, this mode is more liable to the LAN
quality and loading level.
Note: This mode has some limitations and should not be preferred to the
recommended server-based mode unless there are special reasons.

© 2013 Dune HD. All rights reserved. 11
In this mode it is important to specify in the configuration the exact number of
devices in the group.
In case some device turns off, stops responding or loses the network, all other
devices in the group will wait until the device is back on, but after that the lost-
and-found device will continue playback from its playlist position, and other
devices—from their positions, thus, the manual restarting of all devices in the
group should be performed.
Attention: In the serverless mode, the playback on schedule is not supported,
so all Presenters should have the default schedule (“use the basic configuration
all the time”).
Synchronization Accuracy
It should be noted that the synchronization function does not guarantee the
frame-accurate precision.
In particular, if different video modes are set on the devices, it may happen that
devices having 50 Hz video modes do the speed-up by 1/25 of a second for
playback of video clips containing 24 frames per second. This does not take place
with e.g. the 60 Hz video modes.
Also the synchronization accuracy my depend on both the LAN quality and the
loading level, as well as the particular video file specifics.
Playback on Schedule
The “Dune HD Network” system supports performing on a weekly schedule.
To configure playback on schedule, a number of named configurations should be
defined. A named configuration defines options for playlist playback, scrolling text
and graphic logos.
There always exists a named configuration with an empty name, which is called
the basic configuration. When the schedule is not explicitly configured, the default
schedule is used which puts the basic configuration in effect.
The schedule itself is technically a list of time intervals within a week, defined with
a minute accuracy, and for each interval a name of a configuration to use is
specified. The schedule is week-based, that is, every week the behaviour repeats.

12 © 2013 Dune HD. All rights reserved.
If a time period is not mentioned in the schedule, it is considered that the
Presenter should stay off for that period.
Attention: The “off” state requested by the schedule is a special mode of a
player when the display is turned off, but the player software continues
working in order to be able to switch to a new configuration on a schedule, and
to accept a configuration file update as well as IR remote control button
presses (if not locked). So, technically this mode is not equivalent to the usual
“Standby” mode. This also means that if a Presenter is put to the “Standby”
mode, it will not wake up on a schedule until turned on manually.
The three independent activities—playlist playback, scrolling text and showing
graphic logos—follow the schedule independently, and check the necessity to
switch to another configuration at the same moments as the configuration file
update (see the corresponding section of this manual).
The request to stay “off” is processed in the scope of a playlist playback activity.
Other activities just show nothing after the “off” state has been demanded, so if
the “off” moment occurs and the current clip is still playing, it will continue playing
to its end while the scrolling text and graphic logos may already have
disappeared.
Note: Thus, it is a possible situation that at some moment e.g. the playlist of a
new configuration is being played, and the scrolling text from the previous
configuration is still being shown.
Real-Time Clock
The schedule feature requires that a Presenter has correct real-time clock setting.
If the player hardware model does not support hardware real-time clock with a
backup battery, the player may be configured to set the clock automatically on
every power-on by contacting a time server via the NTP protocol.
The player menu Setup > Miscellaneous > Time Synchronization allows to
configure the address of an NTP time server and related options. If the Presenter’s
LAN is connected to the Internet, a free public time server may be used, e.g. the
popular "pool.ntp.org".
In the absence of the Internet connection, using a time server software on one of
the PCs connected to the same LAN may be recommended, e.g.:

© 2013 Dune HD. All rights reserved. 13
∙Windows 2003 has a built-in Time Service which supports the NTP protocol.
Please refer to Microsoft Windows documentation for details, e.g.
http://technet.microsoft.com/en-us/library/cc773013.aspx.
∙For other Microsoft Windows versions, the free NTP server from
http://www.meinberg.de may be installed.
Please refer to the player manual for details.

Usage
Getting Started
In order to start using a number of Presenters in the Digital Signage mode, please
assure the following steps are taken (see the rest of this manual for details) for
each player which is intended to be a Presenter:
∙Install the latest firmware which supports Digital Signage. Please note that not
all firmware versions for a particular player model include the support for
Digital Signage, thus, the version to install will not necessarily be the most
recent for a model. Refer to the official web site for the firmware updates.
∙Obtain and install the license file which includes HDNetwork functionality.
Verify that Setup > Information > License includes HDNetwork license.
∙Connect an HDD or another local storage device (e.g. a USB Flash drive) into a
player. Verify that this device is accessible via the main screen icon, thus, is
not
listed in Setup > Information as a so-called System Storage device. See player
manual for details on System Storage concept. Installing a dedicated System
Storage device is not necessary for the Digital Signage mode.
∙On the HDD, create a folder named "HDNETWORK". No other contents is
required. Of course, when deploying multiple Presenters, the HDDs can be pre-
loaded with necessary content and configuration files.
∙Finally, connect the Presenter to a display and LAN. Appropriately set up video
output mode, network settings and other player settings (refer to the player
manual) which may affect the Digital Signage mode.
Turning On and Off
There are two ways to enter the Digital Signage mode. One is to use the player
menu: select the “Digital Signage” top-level item. The other is to configure a
Presenter to automatically enter the Digital Signage mode on power on and
restart, including return from the “Standby” mode. In either case, when the mode
is entered, the playback according to the playlist and the schedule starts
immediately.

© 2013 Dune HD. All rights reserved. 15
Note: The Setup > Applications > Digital Signage > Enabled option allows to
show and hide the Digital Signage top-level menu item.
To configure the Digital Signage mode automatic start, go to the player menu
Setup > Applications > Digital Signage and set the Automatic start option.
In the Digital Signage mode, the device power may be turned off at any moment.
Using IR Remote
An infrared remote control typically comes with Dune HD players. During the
playback in the Digital Signage mode, it may be used to control the playback, and
to exit the Digital Signage mode to the player menu.
Note: If several Presenter devices are installed close to each other, please take
special care to insure that the IR signal of the remote control is received by a
proper device. Covering an IR receiver of other devices by a piece of carton or
the like may help.

This setting is kept on switch to the next clip, but is reset upon Presenter restart.
STOP Exit the Digital Signage mode to the player menu.
POWER Enter the “Standby” mode.
Please refer to the player manual for details on the “Standby” mode.
Button Lock
In the Digital Signage mode there is a setting (defined in the configuration) which
allows to block the remote control buttons, including the POWER button.
Note: The usual value of this setting is “on”, so it is likely that in your sample
configuration the remote control buttons are locked.
When the remote control is locked, it is possible to exit the Digital Signage mode
to the player menu by typing a special sequence of buttons which is also
configured in the settings. Initially this sequence is tusttust (these
buttons carry letters “stopstop”). When this sequence is typed in, the remote
control lock will be turned off for the player menu, until the next time you enter
the Digital Signage mode.
The button lock function is useful to prevent accidental interruption of the
playback, especially when Presenters are used near some other Dune HD players,
e.g. in a store.
Note: If the synchronized playback mode is turned on in the configuration, the
button lock works as usual, but if the button lock is turned off, only the STOP
and POWER buttons work.
Configuration
The Digital Signage mode works according to the configuration which is defined
by the following:
∙Some settings in the player Setup menu.

© 2013 Dune HD. All rights reserved. 17
To edit these settings, you should use the IR remote control with the Presenter.
∙Configuration file "HDNETWORK/config.txt" on the Presenter’s HDD.
This file may be accessed by FTP/SMB. The Control Center application
reads/changes this file via FTP to allow the user to view/edit Presenter settings.
If you need to work with the configuration file directly, not using the Control
Center application, please refer to the dedicated section of this manual.
Player Setup
The player menu Setup > Applications > Digital Signage allows to configure the
following options:
∙Enabled: Yes/No
If set to “No”, the player menu top-level item Digital Signage is not shown, and
the automatic start of the Digital Signage mode is not performed regardless of
the Automatic start setting.
∙Automatic start: Yes/No
If set to “Yes”, the Presenter will automatically enter the Digital Signage mode
on power on, restart and return from the “Standby” mode.
The automatic start is not performed if the "HDNETWORK" top-level folder is
missing on the Presenter’s HDD.
∙On failure: Stop player/Switch to player menu
In case the Presenter encounters a fatal error during the Digital Signage mode
(e.g. an internal error or a hardware problem like HDD failure), it either returns
to the player menu or enters a special “Stop” mode showing the black screen
until the power is turned off.
In addition to the Setup > Applications > Digital Signage settings, the following
settings (and only them) from the player Setup menu influence the Digital Signage
mode:
∙Setup > Video
∙Setup > Audio
∙Setup > Network
∙Setup > Miscellaneous > Encodings >

Please refer to the player manual for details on these settings.
Local HDD Contents
The internal HDD of a Presenter is expected to have a top-level folder
"HDNETWORK". The contents of an HDD outside this folder does not influence the
Digital Signage mode.
Attention: If the "HDNETWORK" folder is not present, the Control Center
application will not be able to recognize a device as a Presenter. Also, the
automatic start of the Digital Signage mode will not be performed even if such
option is set. Thus, this folder should be created manually before attempting
to configure a Presenter.
The "HDNETWORK" folder contains the following files and folders:
∙clips
Folder containing video clips and static images which may be added to a
playlist. May contain items not included into any playlist. Subfolders are
ignored.
∙logos
Folder containing image files for logos to show over the video. Images should
be in the ".aai" format (see the corresponding section of this manual). May
contain other items and subfolders which are ignored.
Note: Please do not confuse static images (which are included into the playlist
the same way as video clips) and logos (which are shown over the video and/or
static images).
∙config.txt
The configuration file which defines the playlist and other options (see below).
Note: If this file is missing, it will be created by the Control Center application.

Local HDD Access
Each Presenter device has a local HDD, either internal or, when it is absent or the
device does not support it, a USB-connected one.
The contents of this hard drive may be accessed without having to disassemble
the Presenter device. The following means are provided:
∙Via the player menu (Navigator).
∙Via FTP.
∙Via SMB (Windows file sharing).
∙Directly, using an HDD rack (for some hardware models).
∙Via USB, as USB Slave (for some hardware models).
Player Menu (Navigator)
A Presenter device remains a fully functional HD player, so it is possible to exit the
Digital Signage mode and thus get to the player menu (the regular player mode). It
provides a powerful file/folder manager (called Navigator) with network support.
The Navigator allows to create, delete, rename, move and copy folders and files on
a connected HDD and on a network.
Please refer to the Dune HD player manual for the detailed instructions on how to
use the Navigator.
FTP/SMB
Each Presenter can serve as a Network Attached Storage (NAS) device. Other
computers/devices in the local network can access the HDD of the Presenter.
Both FTP and SMB (Windows file sharing) protocols are supported—a Presenter has
built-in FTP and SMB servers. In order to access a Presenter using one of these
protocols, you need to know the IP address of the device (it can be found in the
player menu Setup > Information), in examples below it is substituted with
“#.#.#.#”.
To access a Presenter’s HDD via FTP in Windows, type “ftp://#.#.#.#” into the
address bar of any opened folder. Of course, you may also use any other FTP
client of your choice.

20 © 2013 Dune HD. All rights reserved.
To access a Presenter via SMB, open “\\#.#.#.#\internal_hard_disk” in Windows
Explorer, e.g. using “Start” menu, “Run” command, or the address bar of any
opened folder.
Notes:
1. The usage of specialized FTP clients (such as FileZilla) is recommended for
better performance.
2. FTP access typically provides better performance for file transfer than SMB,
especially when a specialized FTP client software is used.
3. Accessing a Presenter via the network during the playback may result in
some video jerking or stuttering, especially when a high-bitrate video is
playing.
HDD Rack
Some hardware models are equipped with a mobile HDD rack which allows to
quickly remove/change the internal hard drive. The rack with the hard drive may
be inserted into a compatible rack part in a PC, or the HDD may be removed from
the rack
Attention: On some player models, inserting and ejecting of the HDD rack may
be performed only when the power is off (e.g. “Dune HD Mini”), while some
other models allow hot-swap operation (e.g. “Dune HD Center”). Please refer to
the appropriate player manual.
USB Slave
Some Dune HD player models, e.g. “Dune HD Mini”, have the USB Slave function,
which allows to use the player as a USB container for its internal HDD.
For example, you can attach a player to a computer via USB, and copy files from
the computer to the internal HDD of the player. This is the fastest method of
transferring files between a computer and a player.
To use the USB Slave function, perform the following steps:
