Abstract
This paper assesses the media synchronization quality of preventive control schemes employed at sources for stored video and voice over a network. The preventive control techniques are required to try to avoid asynchrony (i.e., out of synchronization). We here deal with two preventive control techniques employed at sources: Advancement of transmission timing of media units (MUs) with network delay estimation and temporal resolution control of video. By experiment, we make a performance comparison among preventive control schemes which employ one or two of the preventive control techniques. Experimental results show that a scheme which exerts the advancement of transmission timing together with the temporal resolution control is the most effective in terms of the media synchronization quality.
