摘要：By subjective assessment, this paper investigates the effects of group (or inter-destination) synchro-nization control in multipoint communications where users have a conversation with each other by using voice and video. The results of our assessment show that the fairness among the users can be kept high by using the group synchronization control in networked competitive work. We also demonstrate that the synchronization qual-ity of networked collaborative work in which the interactivity is not so important can be improved by using the group synchronization control. However, the group synchronization control deteriorates the easiness of networked collaborative work in which the interactivity is important.
