911, which is the most commonly used method in subjective testing. The ACR method shown in Figure 8, which is a single stimulus method where test video sequences are presented one at a time using the test administration application and the human subjects rate independently. The human subjects were given generous breaks to avoid fatigue, and the testing time per human subject varied between 60-80 minutes. Considering the overheads of the protocol stack in mmWave WPANs, we then quantify the minimum channel time needed for each IPTV flow. In this paper, we propose a method to efficiently support high definition video flows in a mmWave-based WPAN with QoS guarantee, considering the characteristics of both the IPTV traffic and the mmWave communication technology. There is an increasing interest in 60 GHz millimeter-wave (mmWave) communication technologies for multi-Gigabit wireless personal area networks (WPAN), aiming to support broadband multimedia applications.
