INTRODUCTION!!
In the modern world, when time became precious than anything else) man began to think of a new technology by which he will be virtually present at the site of his desire without undertaking the strain and loss of the travel. The outcome of such a thought is the videoconferencing technology This new technology is a result of combining the strength and powers of a number of technologies namely communication, networking, video/audio coding and software!) The response and growth of the technology in the present decade is reflecting in its diversified application and it can be rightly called as technology to the present century.
Brief survey of videoconferencing system
Back in the 1960's AT&T introduced the concept of video conferencing at the Newyork World fair and the name given was 'picture phone'. During 1970's full motion two way closed circuit video emerged in boardroom environment. In 1980's by the development of digital TV and progress in compression algorithms circuit based video conferencing appeared. By 1990 with the popularity of multimedia and packet switching networks desktop video system emerged. The latter half of this decade witnessed the development of videoconferencing products by world's leading computer companies like Intel, Apple etc.
Thinking of the potential of the system, World Trade Center (WTC) Mumbai has introduced video conferencing system in March 1997.
What is Video Conferencing?
Video conferencing may be defined as the dynamic exchange of all kinds of information, text, graphics, audio, video etc. in a context of structured conversation organized by item and allowing a participant to contribute spontaneous responses to any item in the conversation. The goal of such a structure of online conversation .nay be decision-making, technical support, community building, project management, distance education, electronic meeting and much more.
An overview of the report
In this seminar titled "Video conferencing system" a theoretical approach has been adopted. Rather than giving a generalized overview of the videoconferencing techniques, its engineering aspects have been discussed. In chapter-1 various types of videoconferencing systems and their features are mentioned. This is followed by the detailed study of a typical video conferencing system in chapter-2. Chapter-3 describes the PC based videoconferencing and its features. The recent trends and versatility application of this emerging technique is presented in chapter-4. Finally the scope, potential and future role of videoconferencing technology in overall communication strategy has also been discussed.
