Title: STREAMING VIRTUAL REALITY VIDEO
Abstract:
An improved streaming of a Virtual Reality [VR] video to a VR rendering device is provided. The VR video may be represented by a plurality of streams each associated with a different view of a scene. A view of the scene may be determined which is to be rendered by the VR rendering device. A subset of streams may be identified which is needed to render the view of the scene. The streaming of the subset of streams to the VR rendering device may be effected by streaming the plurality of streams from a stream source to a forwarding node downstream of the stream sources and upstream of the VR rendering device, and selectively forwarding the subset of streams from the forwarding node to the VR rendering device in response to the view having to be rendered by the VR rendering device. As such, the switching latency between streams may be reduced. Namely, streams which are not needed for rendering a current view, but which may be needed for rendering a next view, may be continuously made available at network nodes nearby the VR rendering device.
