This paper exploits the idea of SCS (Switching between error Concealment and frame Skipping) for H.265/HEVC video and audio IP transmission. The method skips output of video frames with a larger ratio of lost slices than a predefined threshold. It continues frame skipping until new GOP. To assess the effectiveness of the method, we evaluate QoE through a subjective experiment. We employ two audiovisual contents and vary the number of slices in a video frame, GOP length, encoding bitrate, and the amount of background traffic. As a result, we find that the method exploiting the idea of SCS can enhance QoE for the content which has large movement.
