The Subjective Tile-based Assessment for 360\u00b0 Videos (STAV360)

The STAV360 dataset is a subjective 360\u00b0 video dataset.It contains six source 360\u00b0 videos, which are used to construct 72 test sequences using twelve tile encoding patterns. The dataset also includes the subjective ratings and head movement trajectories of 27 users, who watched the videos using a Quest 3 VR HMD. All participants volunteered to take part in this experiment and gave their consent after reading the experiment description and purposes. The 360\u00b0 videos in the STAV360 dataset were captured using an Insta360 Action Camera X4 at 8K resolution (7680 \u00d7 4320) and 30fps. The camera settings were set to encode the videos using HEVC\/H.265 at the highest possible bitrate (200 Mbps). Since the captured videos are stored at high bitrates, they can reliably be used as reference sequences in quality assessment of encoded instances at lower rates.
