What is IG-Class
The distance learning platform IG-Class
constitutes a complete multimedia solution for
distance education using IP data networks,
eliminating the geographical barriers and
offering the best educative support for the
student. Ideal for the students instruction in
educative centers and for the training of
corporate employees.
Its pedagogical key is constituted for being the
only platform of conventional learning at
distance, and that offers the greater economic
advantages to the institutions and companies
that implement it.
Consist of two subsystems, integrated in Web, to offer the best educative solution, and to try to constitute in the ideal training
system:
• Asynchronous system, that incorporates functions such as access to the documentation, teamwork,
accomplishment of exams, electronic mail, agenda, administrative information, etc.
• Synchronous system, that makes possible for the students the access to a real live class, with audio and
video from the teacher, reception and attendance from a limitless number of students, remote visualization of
slides and applications, electronic whiteboard, etc.

The ideal learning system
As base, we are going to propose a series of necessities that must have the ideal learning system, and on which the pillars of
the IG-Class platform rise.
The main ones are the following:
• Reflect the traditional learning in the new electronic media, using
the latest telecommunication technologies and offering a total
interactivity between the teacher and the students.
• Incorporate in the same platform all the set of tools necessary for
the training, including documentation, exams, tools for teamwork
and collaboration, attendance to virtual multimedia classes, etc..
• Facilitate the access to learning for students and workers, being
implanted in students without needing expensive equipment, and
offering savings in the corporative training expenses.
• Very easy to use even for users with little computer skills to make it
extensive to the greater number of students.
• Sustained in standard architectures of the market, in order not to
remain obsolete and to have its extensibility assured in the future.

Traditional and distance learning
Now we will analyze the advantages and inconveniences offered by the traditional and the distance learning systems, for
which we will take a series of characteristics as base, showing the results in the following table.
Thus, it is possible to
appreciate, basically, how
the traditional education is a
proven and very powerful
system, valid for the learning
of a student, but too rigid for
the
training
necessities
needed by organizations like
companies
nowadays.
Nevertheless,
distance
learning, employee by itself,
also have deficiencies that
are due to be solved.
However, IG-Class, by its special conception, is based on the traditional learning, but integrates the
technologies and media to constitute itself in the most powerful distance learning platform, and offers
the advantages of both worlds, without any of the previously mentioned shortcomings.

Scopes and environments of application
The IG-Class platform is extensible to practically any environment, although, due to its characteristics, is clear its
implementation in the following situations:
Educative institutions such as schools, universities, private academies.
IG-Class will allow to reach simultaneously all the students enrolled in a course, without concerning their geographic location,
through a single teacher. Thanks to its synchronous and asynchronous operating modes, it is able to reflect real classes
without neglecting the personal study of the student, access to documentation, accomplishment of tests, etc.
Companies with multiple delegations geographically dispersed
From a single site it will be possible to offer continuous training or specific courses to employees in all the delegations of the
corporation, avoiding travel and lodging expenses, and reaching from the very first moment all the employees, who will not
have to dedicate complete working days to their training, but the merely precise time and will be in the office at all times.
Large corporations for internal communications
In the same way, directive sessions could be organized to reach the
employees, although the sessions be only carried out in a single location, but
the lack of space would make it impossible to concentrate them in a same
place.
In such cases, it would only be necessary the use of a local
network, with a minimum consumption of its capacity for the
session.

Economic advantages
The implementation of the E-Learning IG-Class platform, in addition to the pedagogical advantages previously described,
also offers great economic advantages to the company or the institution that incorporates it.
Thus, for educative centers , we can summarized the following ones:
• Expansion of courses and extension of students, although there is no
more existing physical space in the center, obtaining new clients
through this channel.
• The use of the IG-Class platform has reduced necessities, and even the
accomplishment of virtual multimedia classes precise very little space.
In companies and institutions where employees are trained is even clearer the
benefits obtain by implementing the IG-Class platform:
• The expenses derived from the training of workers, such as travels,
diets, lodging, etc., are eliminated almost totally.
• The employee continues being at the office, and invests only the time precise for his training, since it is
received in his job post. He will not even have to agree in dates and hours with other colleagues.
• Without special space requirements for training, avoiding in addition the concentration in a same place of
employees from dispersed centers. The IG-Class platform reaches all the centers at the same moment.

System characteristics
Ultimate generation of technological standards:
• Client/Server Web technology. Student client totally integrated in Internet Explorer.
• Audio-visual multimedia encoding based in MPEG-4 and in Microsoft Windows Media formats.
• Data transmission by any TCP/IP network using IP Unicast and IP Multicast protocols, taking advantage of any local
network, Internet, satellite, DTT, cable, etc.
Multiple collaboration tools in a real class:
• High quality audio and video of the teacher and students
• Slides presentation in GIF, JPG and Flash formats
• Remote electronic whiteboard controlled by the teacher
• Bi-directional chat in real time between all the class
• Test-type questionnaires with statistics in real-time
• Remote full-screen visualization of Windows applications
• Global Web navigation by Internet guided by the teacher
Complete teacher control of the class, with listing of the
students and their status, managing hundreds of
simultaneous students.

System architecture (I)
Three component 100% client/server architecture, specially designed for its use in networks with IP
Unicast and IP Multicast transmission protocols:
•
IG-Class Server (network and applications server)
•
IG-Class Teacher (teacher station and media encoding)
•
IG-Class Student (student client and system access)
Specially design for its use on IP Multicast networks, with total support of IP Unicast, as much for live
classes as for recorded, being optimized even for the combined and simultaneous use of different networks
at multiple bandwidths (asymmetric networks).
In scenarios with IP Multicast transmission:
• As broadband network it is supported the use of standard corporative networks or wireless networks (satellite, DTT,
DAB, cable and microwave)
• User return through any type of narrowband network (Internet access, GSM, PSTN, ISDN), or the same broadband
network if it is bi-directional.
• Satellite, DTT and DAB has the following advantages:
- Total coverage
- Cost of the service independent from the number of students
- Ease of installation for the student (for example, standard digital TV antenna)
