提出了IP视频音频传输中视频输出方案SCS（Switching between Error Concealing and Frame Skipping）的门限选择接口。我们进行了主观实验与两个阈值选择接口：两个模式的方法和四个模式的方法。这两个接口是用手持设备实现的。然后，我们调查用户属性对QoE的影响。我们将这两种方法与0%方法（纯跳帧）和100%方法（纯错误隐藏）进行了比较。在实验中，我们使用两种内容类型：体育和戏剧。结果，阈值选择接口，特别是四模式方法，实现了比运动中的其他方法更高的QoE。此外，用户属性影响首选阈值。
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.
