Distance Learning


Learning solutions for technology after satellite interactive
Working tele-education technology to create chapters Virtual Virtual classes from which to combine records and several thousands of students using the technology of Meetings visible after development, which allows the student to communicate with the lecturer through the environment interactive media where available to the student views the lecture and talk to the lecturer and lay down questions and received answers and send the reports immediately during the presence of the student in his home.
1. Advantages of distance education

There are many advantages of distance education systems for traditional teaching methods, which can be summarized as:
You do not need systems of education for students after a presence in universities and schools during the lecture which is a burden on universities and academic institutes in the provision of infrastructure and an amphitheater for classes that contain the numbers of students. Given the lack of transfer students to the site of the university that provide students with a lot of time and money is also on the national level, a tremendous savings in resources such as transportation, fuel and cost of establishing and running educational buildings. Systems are characterized by flexible distance education no later received lessons and lectures where the student can attend the lectures as they occur, and enjoy the benefits of virtual classrooms or record lectures and re-watch them, which fits many of the students and staff work as men in some professions. Help of distance education technology to open new markets for the institutes and colleges, and attract students from outside the territorial boundaries of the institutes also allow students to enroll in many colleges, which was difficult to attend because of the post-geographic.
The material recorded for the lectures is an important reference for students, reducing dependence on private lessons. May be a times after mixing in a suitable environment for diseases and epidemics Antphal Konflonza birds and swine influenza in the event of large numbers of students in closed places, which makes the technology of distance education the best solution to avoid outbreak of epidemics in some cases.
2. Different means of distance education technology
Universities and colleges rely on different ways to provide distance education vary in terms of advantages and disadvantages as follows:
2.1 Internet use

Adopt such institutes on the use of systems Meetings visual link between the lecturer and students via the Internet and fit these systems institutes with limited numbers of students with working systems Meetings visual Bertokolat data exchange unilateral contact Unicasting which you have to transfer data from the records to each student through the contact individual and which would raise the volume of data transmitted from the lecturer to the students. For example, when moving image records with the broadcast of material science Kalard inside of Presentation by connection speed 1mbps to get a picture with the clarity of a good number of ten students, it is necessary to the minutes of internet connection through the means of communication not less than speed of 10mbps, which is usually difficult to provide such speed at an economical price or the impossibility of provision at all in case I use a larger number of students, both in terms of technical or economic sense.
2.2 Broadcast TV

Overcomes the problem of broadcast television on the need for high-speed access to it technically difficult in the case of broadcasting to a large number of students where the so-called Broadcast and which rely on broadcast television transmission, either through terrestrial transmission or transmission space to all students on a TV channel and one received by students in their homes through television sets and satellite receivers are available in all homes now. In spite of the plains of delivery but these cannot be flawed by the way students interact with the lecturer where it is broadcast by one as flawed by the high cost of broadcasting where the cost of the broadcast TV channel on one satellite up to thirty thousand dollars a month
2.3 system of distance education using interactive satellite

That system relies on a combination of advantages of two previous methods and avoid Aaoppema. At a cost of up to 25% of the cost of broadcast television and unlike systems operating Bertokolat data exchange unilateral contact Unicasting that need to contact Sraat difficult provided that the system depends on the exchange of data Brtakul multihued Multicasting, which depends on the broadcast the same material to a large number of subscribers Using the same speed required to transfer data to one person is worth mentioning that it is not to use this protocol on the Internet do not allow the technology used in the Internet in the transfer of data from which by this Protocol.
That system was developed using the technology of satellite communications where it is processing the lecture hall VSAT satellite communications system operating on a computer screen broadcast of records, which contain

A vivid picture of the minutes during the explanation Presentation of the lecture Control of the broadcast presentation, or web browser interface or a software Space for text dialogues with students List the names of participating students with the lecturer to control or intervention to allow them to prevent them

And this system has been designed to suit all the different segments of students and provide maximum benefit where the satellite receiver more than one way:
2.3.1 Students who have computers and means of internet connection

For those men students are provided with their own computers with data reception from the satellites, which relate to the computer through the USB port and operates technology, DVB-S and which is provided with packet powerful programs allow students to record lectures and re-watch them when needed and use as a reference as a substitute for lessons Privacy and by means of Internet access traditional phone lines or ADSL, which allows the software package designed by the company development team, SAE, Sat interaction with the lecturer through Ersalrsalh text appears instantly on the screen of records or through voice communication over the Internet.

And allow that method to the student view and record the lecture and immediate interaction with the lecturer at a cost of no more than two hundred Egyptian pounds cost of the receiver.
2.3.2 Students who have computers and do not have the means of internet connection

Have these students to see the broadcast immediately to the lecture when they receive the devices receive data from satellites above at a cost of two hundred Egyptian pounds and if you want to interact with the lecturer it is to provide systems receive and send data satellite VSAT at a cost of five thousand Egyptian pounds and a monthly subscription hundred Egyptian pounds.
2.3.3 Students who do not have computers to Due to the use of technology in DVB-S satellite transmission; it is for these students the reception of such data on a television without the possibility of interaction with the lecturer.

Interactive map shows the broadcast of the lecture directly to the students and received by thousands of students, either through
1 - TVs and receivers lite traditional houses located all
2 - received on computers with the ability to record the lecture and a narrative or voice interaction with the lecturer of the lines of communication through the telephone or ADSL
3 - received on computers with the ability to record the lecture and a narrative or voice interaction with the lecturer through space VSAT transmitters that are providing students.
