Abstract

In virtual reality (VR), 360? video services provided through head mounted displays (HMDs) or smartphones are widely used. Despite the fact that the user's viewpoint seamlessly changes, sounds through the headphones are fixed even when images change in correspondence with user head motion in many 360 ? video services. We have been studying acoustic immersion technology that is achieved by, for example, generating binaural sounds corresponding to the user head motion. Basically, our method is composed of angular region-wise source enhancement using array observation signals, multichannel audio encoding based on MPEG-4 Audio Lossless Coding (ALS), and binaural synthesizing of enhanced signals using head related transfer functions (HRTFs). In this paper, we constructed a smartphone-based real-Time system for streaming/viewing 360 ? video including acoustic immersion and evaluated it through subjective tests.
