Immersive Media Metadata

Support for 360° video, also called omnidirectional video, has been standardized in Omnidirectional Media Format (OMAF) and in Supplemental Enhancement Information (SEI) messages defined for HEVC. These standards can be used for delivering immersive visual content. However, rendering flat 360° video may generate visual discomfort when objects close to the viewer are rendered: the world around the viewer seems flattened. Interactive parallax provides viewers with cues to their visual system, resulting in an enhanced perception of volume around them.
