This paper proposes threshold selection interfaces for the video output scheme SCS (Switching between error Concealment and frame Skipping) in video-audio IP transmission. We conduct a subjective experiment with two threshold selection interfaces: the two mode method and the four mode method. The two interfaces are implemented with a handheld device. We then investigate the effect of user attributes on QoE. We compare the two methods with the 0 % method (pure frame skipping) and the 100 % method (pure error concealment). In the experiment, we utilize two content types: sport and drama. As a result, the threshold selection interfaces, in particular, the four mode method, achieves higher QoE than the other methods in sport. In addition, the user attributes affect preferred threshold values.
