System for 360-degree Video

For interactive viewing of 360-degree video, the video must be processed in its original high-resolution form without pre-processing. Amateras Server has a powerful rendering engine for stable playback of high-resolution video with flexible realtime mapping. By just copying of your 360-degree video file to the server, you can start screening it immediately.

High-res. Live Input Support

In addition to 360-degree video playback, Amateras Server can also capture and display interactive content using high-resolution video capture input function. Image mapping based on projectors and displays placement are handled by Amateras Server, so content creators can focus on creating a wide view content. Amateras Server can switch from interactive content to pre-recorded video seamlessly as soon as the interactive content have troubles.

Born for Immersive Displays

The Amateras system was born as a video playback solution for planetariums and other dome theatres, and was later widely used for projection mapping and other applications. From its beginning Amateras Server is a media server for immersive media that was developed based on the needs of a 360-degree video environment. It has been installed in many permanent theater facilities and interactive event exhibitions, and is the most successful media server in Japan, especially for temporary dome events.

Amateras Dome Player

This is a video playback software dedicated to dome content that is widely used in planetariums and dome theaters. You can watch the dome master and 360-degree contents inside the virtual dome theater. You can also use VRHMDs such as the Meta Quest to view the contents in VR.

Amateras Panorama Player

This tool simulates a 360-degree content displayed on a cylindrical panoramic screen. The field of view of the panoramic theater, which has a very wide screen, is limited by the aspect ratio of the screen. This tool allows you to fully examine camera and scene layout before you start creating or filming your content.

Amateras Room Player

This tool simulates 360-degree content displayed on a room wall. In room wall projection, content appears bent when viewed from a location other than the pre-specified viewpoint center. Before actually building a room display, this tool allows you to check how it will look. It also allows you to confirm in advance that the field of view is greatly limited by the width, depth, and height of the room.

Amateras Encoder

Video contents displayed on Amateras Server needs to be encoded in advance for optimization. This encoding tool is available free of charge, allowing content creators who do not own the Amateras Server to prepare content by themselves for screening. It saves encoding time in the theater, and it simplify check of the video codec, format and so on.

Amateras Slicer

Amateras Server's projection correction result can be exported to movie files for synchronized playback on signage players, to achieve the same kind of video mapping without Amateras Server. Though interactive 360-degree look around and a variety of interactive features will not be available, but you can build a backup system at a lower cost.

Benefits of a Single Server

Amateras Server is designed as a single-server solution, even for large video theaters, whenever possible. This provides the following important benefits:

Since only one computer hardware is needed, costs are lowered and failure rates are minimized.

Since the video is played back from a single source, there is no frame synchronization problems even with many projectors or displays.

Even if you want to prepare a spare server, there is no additional license fee and you only need one more computer hardware.

There is no need to synchronize content files. Just copying a file to the server and it's ready for screenings.

System Scalability

In certain applications, multiple Amateras Server units may be used as a cluster system. For example, only Amateras Server software may be deployed on an existing system's computer cluster to enhance its functionality. In this case, only synchronizing content files to all servers is required, but other than that, the usability is the same as for a single server.

Simple Multi-Projection Maintenance

Amateras Server's simple projection correction feature makes it easy to correct misaligned projections when hitting a projector or changing lamps. In many of the facilities where Amateras Server has been installed, their staff do the adjustment work by themselves.

Troubleshooting for Long-term Operation

Amateras Server has aull system backups storage, allowing for immediate recovery in the event of a storage or OS level failure.

The computer hardware comes with the manufacturer's long-term on-site repair warranty.

Video output layout can be fixed, so the system is not affected by instability of video cables and display devices.
