Adaptive video conference system on a low bit Rate network

الملخص EN

This paper studies video conference system over low bit rate network.

As a result of this study, some ideas are employed to transfer video and audio information through the dial up network with minimum jerky views, discontinuous voice and with a reasonable number of users.

A video conference standard, which contains video standard and audio standard, is chosen to build a developed Video Conference System that takes into consideration the monitoring of the network load, j by using a special designed sensor, called Network Load Sensor.

The NLS is built to sense the network load.

Based on the test results, the video resolution and audio compression ratio vary; continuously.

The system is implemented using visual C++, with using of sockets programming as the; interface between clients and the conference server and the use of the Windows Multimedia Platform (SDK, which support some audiovisual functions).
