Abstract
A low-complexity method and apparatus for frame accurate field of view switching for virtual reality systems may be used principally for streaming virtual reality data systems, allowing optimal and consistent quality for field of view based VR streaming engines. The method and apparatus may also be used for other virtual reality data systems.
Claims27
A field of view switching method for virtual reality data, comprising:
- providing virtual reality asset data, the virtual reality asset data including a plurality of fields of view for each frame of the virtual reality asset having a center field of view and a plurality of neighbor field of views adjacent to the center field of view for each data chunk of a virtual reality data asset, a stream for each field of view and a zig-zag stream for each field of view;
- determining that a viewpoint of a virtual reality device has changed;
- and
- switching the field of view of the virtual reality device on a frame by frame basis from a current field of view representing the viewpoint to one of the plurality of neighbor field of views based on change in the viewpoint of the virtual reality device.

An apparatus for field of view switching for virtual reality data, comprising:
- a hardware storage device that stores virtual reality asset data, the virtual reality asset data including a plurality of fields of view for each frame of the virtual reality asset having a center field of view and a plurality of neighbor field of views adjacent to the center field of view for each data chunk of a virtual reality data asset, a stream for each field of view and a zig-zag stream for each field of view;
- a virtual reality data backend computer system having a processor and plurality of instructions that configured the processor to:
- receive a determination that a viewpoint of a virtual reality headset has changed;
- and
- switch the field of view of the virtual reality headset on a frame by frame basis from a current field of view representing the viewpoint to one of the plurality neighbor field of views based on change in the viewpoint of the virtual reality headset.
