Two-Layer 3DoF+ System Based on Ultra-High Resolution Panoramic Video

Abstract

3DoF+ supports limited movements of the user to better interact with the video contents. It provides user with more detailed information by utilizing the ultra-high resolution panoramic video. However, such high-resolution video poses a great challenge to network bandwidth and client performance. In this paper, a two-layer based 3DoF+ panoramic video system is proposed utilizing the ultra-high resolution panoramic video. According to the user’s viewpoint, this system will select different layer videos to display to provide users with a real overall zooming viewing experience, while effectively saving bandwidth. Experimental results show that the proposed system saves 85.95% transmission bandwidth than the traditional system in average.
