General Information
DVB Explorer is a new-generation portable analyzer that provides detailed DVB component
information. It is perfect for use in the eld but what really makes this product one of a kind is the
fact that it covers all DVB standards - T/T2, C and S/S2. It can receive live DVB T/T2, DVB C
and DVB S/S2 signals and ensures complete and advanced MPEG decoding, ETSI TR 101 290
Layers 1,2 & 3 and multi-PLP analysis including PLP allocation, PLP extraction, T2 timestamp,
T2/L1 pre- and post-signaling, BB frame, PID and EIT Tables.
It also supports MPEG transport stream analysis, plus MPEG-2 TS record and playback and
MPEG-2 TS over IP forward. Powerful, practical and ecient, it has a compact and elegant design
coupled with great features which include a selectable wide range IF lter bandwidth, a spectrum
analyzer allowing checks of the RF carrier, constellation and Echo diagram display and precise
measuring of RF, SNR, BER, CBER, PER, MER, SSI, SQI, C/N, Freq oset. All RF measurements
can be stored into a log le for further analysis. This product lets users select between a predened
DVB channels scan or manual tune. PCR graphs and advanced EIT display are also available.
The device supports all modulation schemes from QPSK to 64QAM for DVB-T, QPS to
256QAM for DVB-T2, QAMQPSK to 32APSK for DVB-S/S2 and from 16QAM to 256QAM for
DVB-C. File-based oine analysis is provided as well. The product oers an audio/video player
supporting H.265/HEVC, H.264/MPEG-4 AVC, MPEG-1/2, AAC, MP3, etc. It also provides
multistream support for DVB-S2, as well as support for DVB-T, DVB-T/T2 & T2 Lite.
DVB Explorer is a solution that has no parallel on the market. Easy to power up via the USB
port of your Windows laptop and available at an aordable price, which further increases its appeal,
this versatile multi-standard product is your must-have portable analyzer.

Before you start
TECHNICAL MATTERS
The DVB Explorer is simple and small. It utilizes surface-mounted (SMD) components, some
of which are ‘application-specic’. Moreover, certain chips require ‘rmware’ programming. To a
large extent this precludes servicing the unit in the eld. For these reasons, and also because of the
small format of this Manual, we have elected to dispense with the schematic diagram, servicing
instructions and a parts listing. Because it is so small and light (and because it is not in the program
signal path!), returning a product such as the DVB Explorer for factory servicing is an option that
we encourage. DEVA Broadcast Ltd. has never considered factory repair charges as a signicant
source of revenue; you would be astonished at how reasonable our rates actually are! Having said
all that, our policy has always been one of ‘full disclosure.’ We feel that, unless you are doing
something nefarious, there should be no reason to hide anything. With a clear conscience we will
cheerfully provide additional documentation and divulge any secrets concerning the DVB Explorer
upon request.
UNPACKING AND INSPECTION
Upon receipt, the equipment should be inspected for possible shipping damages. If such are
found or suspected, notify the carrier at once and contact DEVA Broadcast Ltd. The original
shipping carton box and packing materials should be kept for possible reuse, in case of return for
Warranty repair, for example. Shipping damages as a result of improper packing for return may
invalidate the Warranty!
IT IS VERY IMPORTANT that the “Product Registration Card” included in the Manual be
completed accurately and returned. This will assure coverage of the terms of the Warranty and it will
provide a means of trace in case of lost or stolen equipment. In addition, the user will automatically
receive SERVICE OR MODIFICATION INSTRUCTIONS from DEVA Broadcast Ltd.

Working with DVB explorer
Before launching the software, you must connect the DVB Explorer to one of the free USB
ports of a PC. At least one of the inputs of the ANT or LNB device must be connected to a DVB
signal source. When the software starts, it checks all USB ports for the device and upon nding it,
initializes it.
Selecting a Conguration
First, the Select Conguration window appears. On the right is the information about the
available device, software and status of the USB connection. Right under them is a button to start
the selected conguration.
This manual will use the term conguration to refer to a group of television channels, which are
multiplexed with the aim of broadcasting and are demultiplexed by the receiver. The most widely
used term in Europe is multiplex (MUX), but in France Bouquet is also used. The USA and Canada
use channel with virtual sub-channels.

On the left of the window, the scanning parameters must be selected in succession, after which
the [Start BandScan] button is pressed and the scanning starts. The scanning process can be stopped
by clicking on the [Abort] button. During that process, each newly-found channel is added to the
list of channels in the lower section of the window.
Once the automatic scanning process nishes, each channel can be selected or rejected by
clicking in the checkbox next to it. Clicking on the [OK] button adds the selected channels to the
end of the congurations list.

- 18 -
The [Add] button is used to add a conguration whose parameters are known in advance.
The [Edit] button is used to edit the description of the selected conguration.
The [Delete] button deletes the selected conguration, while the [Clear] button will clear all
congurations from the list and create a new empty list.
The software allows for working with multiple lists of congurations. Each congurations list
is a separate le. The [Open] button is used to select a le of previously created congurations,
which will be added to the list.
The [Save] button is used to save the changes in the selected list of congurations.
It is quite useful, especially when scanning in the DVB-S/DVB-S2 standard, where there are
multiple channels, to clear the list in advance with the Clear button and then save the newly-found
channels in a le with the selected polarization and band.
To continue to the main software screen, select the [Play selected conguration] button. This
button is active only when a conguration has been selected from the list, a DVB Explorer unit
has been found and the communication with it is error-free, i.e. the Device status and USB status
elds are green.

Main Window
The main DVB Explorer screen is functionally divided into four parts.
On the left are three sections containing information derived directly from the transport
stream packets. They are presented as tree structures - Transport stream tables, Services, PIDs.
Each section is selected by a left click of the mouse on the section title. The sections are also
automatically activated upon selecting the tabs - RF, Bitrate and Service. A detailed description of
the functionality of each section can be found further on in this Manual.
To the right of the tree section are six tabs: RF, Bitrate, Service, PCR, EIT and TV. The tabs are
activated by selecting the tab title with the mouse. Each tab provides specic information about the
selected conguration. A detailed description of the functionality of each tab can be found further
on in this Manual.
The space under the tabs is divided into two sections - ETSI TR 101 290 and Log Info. The rst
section provides clear information about measurement errors and DVB transport streams analysis
in accordance with the ETSI TR 101 290 standard. Log Info brings up specic information from
events during the operation of the software.
The lower section of the main screen contains information about the currently selected
conguration and the buttons to manage the DVB Explorer.

Management Buttons
[PLAY] – This is the button that starts the measurements and the analysis of the input signal
from the selected conguration.
[STOP] – Stops all actions related to the analysis of the selected conguration. The same
conguration can be started again using [PLAY]. The Conguration button is used to select another
conguration, if a change is needed.
[RECORD] – Used to record the transport stream (TS) of the selected conguration into a le.
The path and the le name can be set directly or selected by clicking on the yellow folder button
after the le name eld. The parameters for duration and size of the le are optional but if they are
selected, the record will stop upon fullling the rst condition.
[Video] – Used for local streaming of the input data from TS to external UDP video players –
VLC, Windows Media Player, etc.
The DVB Explorer settings allow for specifying the path to VLC and the optional parameters
upon starting it (see “Streaming Settings” on page 23). If VLC is installed and its settings are
correct, VLC will start automatically.
