The Effect of Bandwidth Allocation Methods on QoE of Multi-View Video and Audio IP Transmission

This paper compares two allocation methods of bandwidth for each video traffic in multi-view video and audio transmission over bandwidth guaranteed IP networks. The methods are a main viewpoint prioritized allocation method and an equally allocation method. We assume simultaneous video transmission of multiple viewpoints. When bandwidth is insufficient for simultaneously transmitted multiple video streams, we investigate the effect of two allocation methods on QoE. We conduct an subjective experiment with the combination of bandwidth allocation methods and playout buffering time. As a result, we see that the appropriate allocation method and playout buffering time change by available bandwidth and contents.
