We propose a system that can provide the physical presence of remote events through a head mount display (HMD) and a headphone. It can stream omnidirectional video within a limited network bandwidth at a high bitrate without sending regions that users are not viewing. It can also reproduce binaural sounds by convoluting head related transfer functions and angular region-wise separated signals. Technical demos of the system using an Oculus Rift HMD with a headphone will be performed to enable users to experience the visual and acoustic immersion it provides.

NTT Media Intelligence Laboratories and DWANGO Co., Ltd. have jointly developed a virtual reality system that enables users to have an immersive experience visiting a remote site. This system makes it possible for users to watch video content wherever they want to watch it by using interactive streaming technology that selectively streams the user's watching section at a high bitrate in a limited network bandwidth. Applying this technology to omnidirectional video allows users to experience feelings of presence through the use of an intuitive head mount display. The system has also been released on a commercial platform and successfully streamed a real-time event. A demonstration is planned in which the details of the system and the streaming service results obtained with it will be presented.

We propose a video streaming system that lets users view their favorite sections through an HMD (head mount display) from a video recorded by a spherical (360-degree) camera. Although spherical video streaming tends to consume a lot of bitrate for its huge image area, our system consumes a reasonable amount of bitrate by assigning higher bitrate only for the user's viewing area, not for the area outside of it. Technical Demos of the system with an Oculus Rift HMD will be performed to demonstrate it enables them to view images at a bitrate of about 2.5 Mbps.

We propose a new interactive panorama video delivery system that enables users not only to select favorite parts of an event site, but also to watch repeatedly with stable and the user-selected camera trajectory. In this paper, we present a system that makes a favorable and stable camera trajectory as a scenario from user's manipulations of a tablet device in a format that can be easily shared with others. We also evaluate the validity of the camera trajectory results obtained our stabilization technique.

We propose a scenario-driven interactive panorama video delivery system that allows users to repeatedly watch the enjoyable parts of an event and share them with others. It provides functions for interactively watching panorama video parts, as well as for scenario making (with user-selected camera trajectory), and delivery that allows users to share their panorama watching experiences. In this technical demos, we demonstrate the system that can make a favorable and stable camera trajectories as a scenario from intuitive user manipulations of a tablet device in a format that can be easily shared with others.
