Claim 13:
14. A method, comprising:
determining a location of a pixel of a current block within a video frame;
determining a predicted location of the pixel within the video frame based on a motion vector for the current block;
mapping the location of the pixel and the predicted location of the pixel from the video frame to locations on a sphere;
determining rotation parameters associated with the current block based on the locations on the sphere; and
decoding the current block for display in a 360 degree video using the rotation parameters,
wherein a block partition size for the current block is determined based on a density distortion according to a location of the current block on the sphere and is between a minimum block partition size and a maximum block partition size defined for a latitude range of the sphere which includes the location of the current block on the sphere.
