Wireless streaming of high-definition video is a promising application for 60 GHz links because multi-Gb/s data rates are possible. In particular we consider a sports stadium broadcasting system where video signals from multiple cameras are transmitted to a central location. Due to the high pathloss of 60 GHz radiation over the large distances encountered in this setting, the use of relays is required. This project designed a quality-aware coding and relaying algorithm for maximization of the overall video quality. We considered a scheme where the source can split its data stream into parallel streams that can be transmitted via different relays to the destination. Simulations show that the proposed scheme outperforms other schemes that do not take the peculiarities of millimeter-wave video links into account. Our results indicate that high quality transmission is possible for at least ten cameras over distances of 300 m. Furthermore, optimization of the video quality gives results that can significantly outperform schemes that only aim to maximize data rates.
