Definition

Teleconferencing is an aggregation of audio conferencing, video conferencing, and data conferencing, and includes multiple participants in a live real-time session.

Introduction

Teleconferencing (a.k.a. Multimedia Conference Services [1]) consists of a live real-time session between multiple participants with the ability to hear and see each other as well as share data and applications. Alternatively, teleconferencing can be thought of as an aggregation of audio conferencing, video conferencing, and data conferencing(or application sharing). Although a subject of interest for many years, teleconferencing has recently grabbed a lot of attention due to current economic and social trends, which emphasize the need for rich media communication between geographically-distributed people. Economic incentives include cutting traveling costs, as well as reducing security risks, and increasing worker availability, whereas social incentives are...
