A Quality Comparison of Preventive Control Schemes for Media Synchronization of Voice and Video Streams

Abstract

In this paper, we assess the media synchronization quality of preventive control schemes at media sources and media destinations for voice and video communications.Two preventive control techniques are considered at the sources:Advancement of transmission timing with network delay estimation and temporal resolution control of video.Three preventive control techniques are considered at the destinations:Change of buffering time with network delay estimation, preventive pausing,and preventive shortening of output duration.By experiment, we make a comparison of the media synchronization quality of preventive control schemes that use these preventive control techniques.
