Abstract

In this paper, we present a hardware architecture and a software architecture for computer based teleconferencing systems. And also we analyse stream activation mechanisms for them from the viewpoint of delay. MuX that is a multimedia I/O server provides various processing elements for data I/O, synchronization, interleaving and mixing. We describe methods to build teleconferencing systems with the elements and compares the technique using master clock with the technique using self clock. In the phase of data input, the technique using self clock is better than the technique using master clock. When we generate interleaved stream from audio and video stream and activate channel objects by periodic audio stream as activation clock, delay from input audio stream to interleaved stream is reduced but delay for video stream is not reduced as much as in the case of audio stream.
