Abstract :
This paper studies the QoE-Based Video Output Scheme SCS (Switching between error Concealment and frame Skipping) for audio-video IP transmission in terms of QoE; it adapts the threshold-setting method of SCS to time-varying traffic. The conventional error concealment method corresponds to a constant threshold value of 100%. We then employ three adaptive methods for threshold-setting; looking up into a reference table, setting by estimating QoE, and selection by the user. We conducted subjective experiments on the four methods for combinations of two contents, three picture patterns, and two patterns of variation in the amount of load traffic. We assessed QoE by the method of successive categories. As a result, we observe that the adaptive methods can achieve higher QoE than the conventional error concealment method for time-varying traffic.
