Real-time 360-degree video streaming over millimeter wave communication

This paper provides an adaptive scheme of real-time video streaming in millimeter wave (mmWave) system. It consists of two parts: (1) real-time video streaming over mmWave 802.11ad 60 GHz wireless link; (2) 360-degree video decoding, post-processing and displaying by using Scalable high-efficiency video coding (SHVC). The mmWave communication is high-speed wireless technology to increase the capacity of video transmission. However, the current video streaming over mmWave researches are for long-distance and mobile device almost processes many tasks such as video decoding, post processing and display by itself. Therefore, the performance of mobile device is quite low in case high-resolution video streaming like 4K. In addition, the synchronization of real-time video streaming in high speed is big issue to ensure the quality of service (QoS), especially when mobile device is moving. Thus, this paper focus on real-time video streaming over mmWave with optimized QoS for high-resolution video. Specifically, this paper implemented an offloading mechanism to handle the offloading task between two UEs. The experimental demonstration shows that the proposed scheme provided real-time video streaming with high performance in accepted QoS-sensitive video streaming applications.
