Research and application of immersive panoramic VR image technology in the fi eld of short video live broadcast
Abstract
With the continuous iteration and upgrading of panoramic VR image technology, panoramic VR has gradually entered the fi eld of
short video, and major short video platforms have gradually expanded the panoramic VR image content ecology. The immersive and interactive
panoramic VR live broadcast gives the live broadcast a new user experience. However, compared with ordinary video, the data amount of VR video
is far more than that of ordinary video, and the live bandwidth required by VR video is also far more than that of fl at video. Therefore, the current
network bandwidth is not enough to support high-quality VR live streaming. Therefore, this paper proposes a VR live broadcast scheme based on
the user’s fi eld of view. By calculating and extracting the user’s fi eld of view area, the user’s quality remains unchanged, the video quality of the
non-fi eld of view area is reduced, and the network bandwidth required for live broadcast is greatly reduced.
