Abstract

Multimedia desktop conferencing systems that include audio, video and application sharing are gaining momentum and increasingly becoming a reality. This paper describes one such system called Java Collaborative Environment (JCE). The application sharing component of JCE allows the conference participants to share any application written in Java using its Abstract Windows Toolkit (AWT). The audio and video components of JCE are based on the new Java Media Framework (JMF). In this paper, we describe the problems encountered during the use of JMF in a conference with a large number of participants. The problems are caused by using the real-time transport protocol (RTP) within JMF for sending and receiving many audio and video streams. Our solutions to these problems are based on using a video multiplexer and an audio mixer. The video multiplexer is to display the videos of many participants into few video windows and the audio mixer is to combine all audio streams into one.
