Abstract: In the last times, the mobile terminals have experienced an accelerated technological development. This
evolution has provided numerous advances in presentation and interactivity in general and it has given rise
to the generation of numerous applications for it. Following this line; this article shows how to incorporate
on mobile terminals a simple interaction with the environment across the technological successor of the bar
codes: the two-dimensional codes. We will use three basic elements -camera quality, growth in data traffic
and increased bandwidth in mobile phones- to create a platform that provides to the user an easy and useful
way of obtaining information multimedia that improves his relation with the environment. We will look for
a complete and global development of the system, that is, the generation of the two-dimensional code; his
interaction with the platform and final obtaining of the information in the terminal.
Throughout its history, mobile phones have been
used for more tasks than serving as a voice
communication device Thanks to the quickly
advance of mobile technology, we can add new
applications that solve or improve access to
information or communication. One of these
contributions is the exhibited in this article and it is
related with the two-dimensional codes. These codes
allow to store more data and more efficiently than
traditional bar codes. This new technology, two-
dimensional codes, properly applied, can save the
existing limitations, and give the user an easy way to
interact with the environment and multimedia
information to enrich their relationship with it. This
technique should take advantage of two stimuli easily
verifiable which are the following two:
Best multimedia and data communication (in
particular, the diffusion of mobile terminals
with built-in camera is growing)
The forecast for the next years point out that,
while the global voice traffic will increase
linearly, the data traffic will do it exponentially.
That is the reason why it is necessary a work of I +
D + i; in order to design a platform to deploy
services based on two-dimensional codes and that
is also scalable and configurable
2.1 Barcodes and Two-dimensional
The bar code (IEEE, 2008) is a code based on the
representation by a set of parallel vertical lines of
different widths and spacing which together contain
certain information. Currently, the bar code is
massively deployed globally. There are several
papers studying barcode readers using the camera
device in mobile phones (Ohbuchi; Hanaizumi;
Hock, 2004), (Tasos Falas, Hossein Kashani, 2007),
(Yue Liu; Bo Yang; Yu Yang, 2007). The problem
arises when you want to store a certain amount of
information. In short, traditional bar codes are very
limited in the amount of information which can be
stored and this give rise to another, more appropriate,
codes to the current market. That's when the idea of
two-dimensional codes arises.
Two-dimensional codes (TEC NEWSLETTER,
2008) are matrices formed by the combination of
dots of certain colours allowing a subsequent scan
by a reader in a very quick and efficient way. There
are a lot of types of two-dimensional codes such as

Figure 1: General structure of a DataMatrix code.
The complete development of the system is reached,
from the generation of the two-dimensional code up
to the final obtaining of the information in the mobile
terminal. Definitively, it will be necessary implement
the following aspects:
Application for two-dimensional code
Architecture and platform for the diffusion of
the application for the recognition of the
generated graph.
Platform architecture and on-demand video
System for receiving and sending MMS with
images requested by the mobile terminal.
For an overview and anticipate the tools used, in
the following image shows the general pattern:
Figure 2: Basic scheme of the platform.
As can be seen, a number of tools (Darwin
Streaming Server, Tomcat, MySQL, RedBox, etc.)
software and hardware will be required which are
shown here.
3.1 Multi-platform Messaging: RedBox
The operation of RedBox (RedBox-Vodafone, 2008)
is very simple. Basically consists of making a bridge
between the mobile and the applications that are
programmed to send and receive SMS, MMS, etc.
All SMS sent by a mobile terminal to reach the
platform, are forwarded to a particular website.
From these web applications, the user may be
capable of sending SMS, MMS or request the
location of a particular mobile terminal which has
previously been discharged from the service LBS.
3.2 Videos on Demand
The concept of VOD or Video On Demand (VoD)
consist in the possibility of, through a specific
interface, to view a video hosted on a server through
the technique known as "streaming". The
transmission protocol used for distributing video over
the Internet (TCP / IP) is RTSP (H. Shulzrinne, R.
Lanphier, 2007). For this project has been chosen the
so-called Darwin Streaming Server.
The system implemented must meet the following
Generate two-dimensional codes with three
different formats: URL, plain text and SMS.
A mobile terminal may, by the send of an
SMS, to receive the application made to read
two-dimensional codes.
4.1 Server
The central element of the platform is the server,
which will be equipped with the Ubuntu operating
system 6. It’s necessary to install other tools, yet
explained. It is; therefore; essential requirement to
MySQL: To collect data from mobile terminals.
DarwinStreaming Server: Copying the files
properly in the folder, will be possible to access
each of the videos by clicking the following
way: rtsp: / / SERVER_IP: 554/NAME_FILE
Tomcat: Installation of this web server will
contain all three web applications made for this
platform (generation of two-dimensional code,
the compilation of statistics and management of
4.2 Applications
Applications developed can be divided into two
main groups: Generation of two-dimensional codes
and RedBox management and statistics.
4.2.1 Code Generation
The first application developed will be responsible
SIGMAP 2011 - International Conference on Signal Processing and Multimedia Applications
for generating two-dimensional codes (namely, QR
and Datamatrix) by completely dynamic way and
with a user-friendly graphical interface.
Figure 3: Interface two-dimensional code generator.
The following figures show the two-dimensional
symbols (QR and DataMatrix) associated with a web
address with the URL: This is the
result of this application code generation:
Figure 4: QR Code (left), DataMatrix (right).
4.2.2 RedBox Management
RedBox manages the incoming requests from users
and the SMS or MMS from the application to a
particular mobile phone. The previous set of actions
can be divided into three main blocks:
Block I: This block is responsible for receiving
information from RedBox. Depending on what
comes, take a particular decision making any
module block II to act.
Block II. This block will act accordingly,
depending on the orders laid down by the block
I: Send an SMS, send an MMS or store some
information in the database.
Block III. Block assigned to receive
notifications and subsequent writing them in
the database.
5.1 Multimedia Results
Let's start with the request to download a two-
dimensional code reader. To obtain an application
will be necessary to send an SMS from our mobile
to phone number of RedBox (600124XXX) with
content "focuses lectorc2d." Automatically; RedBox
redirect to the application developed and it will pick
up the petition that the user is asking. Thus, the
method adopted is to send an SMS with the URL I-
Nigma Reader. So, the user can access the URL of
the reader and can download the specific application
for his mobile model. The following illustration
shows this procedure:
Figure 5: Process for obtaining a code reader.
With a simple click you can proceed with the
installation and the terminal will be ready to read
QR codes previously generated.
To view a web page through a QR code in the
first place we will start the application. Next, we will
focus on the QR code generated and automatically
interpret what type of content is. Simply; with a
click on the "Connect" will enter the requested
website. In the following illustrations we can see the
process of viewing web through a QR code:
Figure 6: Viewing a web through a QR code.
The next step is to verify that the RedBox system
for displaying images works correctly. Through a
QR code, which is interpreted like a sending of a
SMS with a specific keyword and after the
developed application will send to the mobile
terminal, an image based on the words entered in the
content of SMS.
Figure 7: Image display process RedBox.
It will be necessary hope that RedBox acts
adequately sending to the developed application, the
request that has been requested by the user. This
application will realize how the user are trying to
download a map image and then it will send an
MMS to RedBox to carry out the sending this image
to the mobile terminal.
Finally, we check the video display on the
terminal through video streaming. To do so, the user
should access a URL very characteristic since the
protocol to be used will not be "http" but "rtsp". The
terminal N95, used for the development of the
project, will interpret that it is a question of a
transfer for streaming and will automatically open
his streaming video player to start viewing the video.
Figure 8: Video visualization process.
5.2 Statistical Results
This section is responsible for displaying different
statistics generated by the system RedBox. A series
of tables are created where the information stored in
the database appears.
In the first table will display data as total
requests, demands complete, incomplete or
erroneous. In the second table the requested requests
are stored supplying data; as data of the request, the
type, the origin and the message. In the third table
(table 1), a list of all requests sent to the platform
and the type of message requesting will be shown.
Table 1: Mobile table requests.
You can study the integration of these codes in
various scenarios that generate added value.
An application of QR codes is the possibility of
incorporating them along a cultural visit, for
example, in a museum next to a sculpture or a
painting, where, to take a picture the code in
question, will facilitate the reproduction an audio
Also, in the poster for a concert you can include a
QR code to provide access to buy the ticket through a
secure payment platform (via web). Then it will be
provided a link to an image with a QR, which is your
e-ticket. Only have to access this link to download it.
The mobile terminals are increasingly smaller sizes
to provide user mobility. But as a disadvantage,
appears to have to enter web addresses in the
browser using a keyboard too small. This article has
been shown how the use of QR codes facilitates this
work. QR codes are based on open standards,
allowing us to use in any environment without
restrictions. This makes the QR useful for mobile
payment platforms and applications through mobile-
oriented web pages. This opens a wide range of
development opportunities in the mobile
environment. It requires a joint effort of all actors
involved in technology development and public
administration to facilitate standardization and
technology integration. Also, the advantages QR
codes have been joined the use of the Platform
RedBox Vodafone. The integration of the two makes
it even easier access to mobile Internet.
