Abstract
A video encoding method includes: encoding a projection-based frame to generate a part of a bitstream, wherein at least a portion of a 360-degree content of a sphere is mapped to projection faces via cube-based projection, and the projection-based frame has the projection faces packed in a cube-based projection layout; and signaling at least one syntax element via the bitstream, wherein said at least one syntax element is associated with a mapping function that is employed by the cube-based projection to determine sample locations for each of the projection faces.
