Abstract

This paper presents an empirical study of several policies for managing the effect of delay jitter on the playout of audio and video in computer-based conferences. The problem addressed is that of managing the fundamental tradeoff between display with low latency and display with few gaps. We describe a particular policy called queue monitoring which observes delay jitter over time and dynamically adjusts display latency in order to support low-latency ...
