This specification provides technologies for interoperable Virtual Reality services with focus on streaming and consumption.
Virtual Reality (VR) is the ability to be virtually present in a space created by the rendering of natural and/or synthetic image and sound correlated by the movements of the immersed user allowing interacting with that world.
Suitable media formats for providing immersive experiences are specified to enable Virtual Reality Services in the context of 3GPP bearer and user services.
The present document defines interoperability points for Virtual Reality for streaming services. Specifically, this document defines rendering scheme requirements, media profiles and presentation profiles for Virtual Reality. The specification builds on the findings and conclusions in TR 26.918.
