摘要

This paper makes multidimensional QoE comparisons of GUIs for threshold selection in the QoE-based video output scheme SCS in audio-video IP transmission. SCS switches between error concealment and frame skipping by comparing the ratio of video slice loss in a video frame with a threshold value. For the purpose of adapting SCS to individual users' inclination, we need to create some appropriate threshold selection interfaces and give the option to select a threshold value to the user. We propose two new interfaces: a slide bar method (choosing a threshold value by a slide bar), and a two mode method (selection of one out of two modes by two buttons). In the latter, a threshold value is set according to the mode. To assess QoE multidimensionally, we conducted subjective experiments on four methods: the conventional error concealment method (100% method), a previously proposed interface called the radio button method (selecting a threshold value by four radio buttons) and the two new interfaces. As a result, we observe that the two new interfaces can achieve higher overall audiovisual QoE than the conventional 100% method and the radio button method. In addition, we show that the slide bar method achieves the highest controllability whereas it imposes a burden on the user and that the two mode method imposes the lightest burden on the user among the three interfaces while it provides high QoE.
