- Abstract
- Immersive video streaming has become very popular. To increase the quality of experience (QoE) with immersive media, user movement adaptive video streaming, three degrees of freedom plus (3DoF+), has emerged and is expected to meet this growing demand. Satisfying the limit of the bandwidth, providing high-quality immersive experience is challenging because 3DoF+ system requires high resolution, multi-view video transmission. This paper proposes a stride based 3DoF+ 360 video streaming system and introduces two main ideas: (i) a multi-view video redundancy removal method using view synthesis, (ii) a multi-view video residual packing method. The proposed multi-view video compression method removes redundancy between videos and packs them into one video, and it exhibits a BD-rate saving of 36.0% in maximum compared to the results of the high-efficiency video coding reference model. In addition, the proposed system requires fewer number of decoders for the clients, and it decreases the burden for immersive video streaming.
