Query: QoE assessment for SVC streaming in ENVISION   Scalable video coding has drawn great interest in content delivery in many
multimedia services thanks to its capability to handle terminal heterogeneity
and network conditions variation. In our previous work, and under the umbrella
of ENVISION, we have proposed a playout smoothing mechanism to ensure the
uniform delivery of the layered stream, by reducing the quality changes that
the stream undergoes when adapting to changing network conditions. In this
paper we study the resulting video quality, from the final user perception
under different network conditions of loss and delays. For that we have adopted
the Double Stimulus Impairment Scale (DSIS) method. The results show that the
Mean Opinion Score for the smoothed video clips was higher under different
network configuration. This confirms the effectiveness of the proposed
smoothing mechanism.
