Executive Summary

This paper compares interactive Multi-View Video and Audio (MVV-A) IP communications and interactive Single-View Video and Audio (SVV-A) ones in terms of QoE. The authors employ a task which makes use of characteristics of interactive MVVA and perform a subjective experiment. They conduct multidimensional assessment and principal component analysis of QoE with 14 pairs of polar terms by the SD (Semantic Differential) method, which can assess an object from many viewpoints. They also assess the efficiency of the task objectively. As a result, they see that the users are more satisfied with MVV-A than SVV-A owing to viewpoint change.
