Executive Summary

This paper studies a method of enhancing QoE (Quality of Experience) in H.264 - video and audio IP transmission by jointly applying FMO (Flexible Macroblock Ordering) and SCS (Switching between error Concealment and frame Skipping), which is a QoE - based video output scheme simply based on the receiver's operation. The authors conducted objective and subjective experiment on the method for combinations of two slice group map types (interleaved and dispersed), four contents and three picture patterns (I, I+4P's and I+14P's); they measured QoS (Quality of Service) and then assessed QoE in terms of the psychological scale.
