Abstract: A virtual reality (VR) device stores an encoded 360° VR video that includes a sequence of video fragments. Each video fragment includes a plurality of flat layers and each flat layer is at least one equirectangular image frame associated with an image metadata. The VR device is configured to render the plurality of flat layers in each video fragment as a plurality of concentric spherical layers projected at a plurality of depth values. The VR device is further configured to receive a plurality of user inputs associated with a modification of a set of attributes in the image metadata. The VR device is further configured to generate a modified image metadata for different concentric spherical layers and control playback of each video fragment in accordance with the modified image metadata for the different concentric spherical layer.
