摘　　要：Face-to-face Videoconferencing is a popular option for many large organizations because it minimizes the need for travel. Instead of continually paying for traveling expenses, a company can either pay to set up a high speed network which has many usages （including videoconferencing） or they can rent time on an existing network. Employees will also no longer be burdened with the need to travel. While face-to-face videoconferencing performance is heavily influenced by the underlying hardware and software, a good video compression scheme can help make the best use of videoconferencing and provide a high quality picture. H.263 standard is now widely used for real-time video communications over a range of networks including the Internet. A frame work for better understanding the H.263 including the implementation of encoder and decoder for face-to-face videoconferencing is presented. This software was written in C＋＋ language, running under the Microsoft Windows operating system.Face-to-face Videoconferencing is a popular option for many large organizations because it minimizes the need for travel.
