A TMO-based approach to tolerance of transmission jitters in tele-audio services

Abstract

An approach to realizing high-quality audio streaming tele-audio services over networks by applying the global time based coordination principle is presented. The goal is to play the audio stream at a remote site with minimal loss of the temporal relationship among the audio data units in spite of the jitters in the transmission delays over networks. The results of a feasibility evaluation of this global time based approach for audio streaming teleaudio services with tolerance of transmission jitters are presented. The effective programming tool used was the Time-triggered Message-triggered Object (TMO) programming tool, a tool enabling construction of real-time distributed computing programs in the form of networks of high-level easily analyzable real-time objects.
