Executive Summary

For audiovisual and haptic interactive IP communications, the authors propose a media adaptive intra-stream synchronization control scheme, which exerts control suitable for each media. They assess QoE (Quality of Experience) of the following three intra-stream synchronization control schemes: media adaptive buffering, skipping & buffering and buffering. Schemes 1 and 2 are examples of the media adaptive intra-stream synchronization control scheme. In media adaptive buffering, they set the playout buffering time for each media according to its property. In skipping & buffering, they apply Skipping to haptic media and playout buffering to video and audio. Scheme 3 is the conventional playout buffering, which sets the same playout buffering time to the three media.
