Introduction

1.1 Background of the Study

As computer and electronics technology continues to grow over the ages, many new innovations continue to flood the industry, creating machine and avenues through which human activities can be enhanced.

The development video messaging over media is an important aspect of this growth in technology. Such information was then able to be packaged and transmitted remotely from source to intended users. But this was rarely a real time scenario. The best we can get out of this was a live coverage of an event, which was usually of high cost and difficult for individuals to own.

The advent of the internet offered better opportunity for inventors to think of better ways of making the communication of video information from source to target in real time and with less cost. Many equipment have been developed to this effect. Further improvement has given birth to what is now known as teleconference.

The word ‘tele’ means distance. The word ‗conference‘ means consultations, discussions. Through teleconferencing two or more locations situated at a distance are connected so that they can hear or both see and hear each other. It allows the distant sites to interact with each other and with the teaching end through phone, fax, and e-mail. The interactions occur in real time. This means that the learners/participants and the resource persons are present at the same time in different locations and are able to communicate with each other. In some situations, questions can be faxed/e-mailed early for response by the resource persons conference is further described by Matthew Lombard and Theresa Ditton as ―an illusion that a mediated experience is not mediated.” Today, it often considers the effect that people experience when they interact with a computer-mediated or computer-generated environment.

The conceptualization of presence borrows from multiple fields including communication, computer science, psychology, science, engineering, philosophy, and the arts. The concept of presence accounts for a variety of computer applications and Web-based entertainment today that are developed on the fundamentals of the phenomenon, in order to give people the sense of, as Sheridan called it, ―being there.” Since teleconferencing is actually a useful tool in organizations because it is solely used to bridge the geographical distance between two or more companies, and from my research, I have discovered that it is only big companies that can actually afford it, so I designed this project inorder to curb that trend that is allow smaller companies purchase and also make use of it.


1.2 Aims and Objectives

The major objective of this work is to develop a Computer Based Teleconference. It also targets at contributing to academic research work.


1.3 Justification for the project

The need for a teleconference system is obvious for several reasons as shown below:

  1. It Impacts on education by allowing live participation without physically being present for a lecture
  2. Legal issues can still be treated even when a person is not fit to go to court
  3. Press men can attained international conferences without having to be physically present
  4. Telemedicine is possible because of teleconference
  5. It makes the best use of the available resources by expanding the learning opportunity and taking the resources to the learners.
  6. It overcomes time or scheduling problems for the learners who can assemble at a learning center for a limited period only because of their full time or part time work, and family and community commitments.
  7. It can be designed to meet local specific requirements of training in terms of content, language and conditions.
  8. Training is of high quality and consistent. There is exposure to multiple perspectives from the primary sources, and therefore as the input from the resource persons is direct, there is little loss of quality in transaction.
  9. There is greater appeal, motivation and retention of information as a variety of teaching methodologies are used.

1.4 Scope of the Project

The scope of this work will include the following

  1. A dynamic Network system that can communicate in real time
  2. To be able to implement a video streaming server.
  3. Explore the power of visual basic in data handling

Summary, Recommendation And Conclusion

5.1 Summary of findings

I am glad to have finished such a project although a lot of problems were encountered during the design and implementation phase, it seemed to be worth it because it turned out to be an opportunity to do some thing of that magnitude and complexity, which of cause, has exposed and taken me deep into programming especially with the use of Visual Basic Programming language and all of the wonderful features it has to offer. This project has been a challenging and fulfilling one because it took me much time and effort to develop and the final output proved it to be worth it. Today, with the internet in place, organizations can now hook up to their websites and get a teleconference system without the hug cost of installing necessary equipment for this.


5.2 Limitations of the project

The achievements mentioned above were however not without its attendant challenges. These are as follow:

Difficulty in gathering the necessary materials: These was really challenge for me, It was difficult to get the much-needed information on which to implement this project. Most business outfits seem to be too busy and reluctant to attend to my request of getting relevant information. My suggestion is that the school authorities should assist student who experience such setbacks in their project design by way of organizing a forum where such problem can be discussed with the cross section of the public.

Unsteady power supply: There was continuous power failure most time especially during the implementation stages of the project. Although this is more or less a common problem in this country, its negative impact becomes more apparent, unbearable and crippling when you are working against time. Power Holding Company should do a better job by ensuring that there is at least a fairly steady power supply.

Time and money spent: An appreciable amount of time and money was spent browsing the internet to get more additional information that would facilitates the smooth implementation of the project.


5.3 Recommendations

Project design and implementation is a continuous process; this is the same in computer and software development. However, I recommend this teleconference system for all schools, hospitals, financial institutions and other industries. This system will be useful since it is computerized and will promote effective, efficient and improved service delivery, thereby promoting profit oriented activities and save time and transportation cost.

5.5 Conclusion

Computerization of a video conference is an important aspect to consider in the live of every organization. A situation where meetings and other crucial gatherings such as conference, lectures media briefing and others can be actualized by a single click of the mouse is not just interesting but a sought after. This work has contributed in the development of computer based Teleconference system. A working model of the work was submitted alongside this report.
