Omnidirectional video coding typically involves mapping spherical image data onto a two-dimensional plane by means of a projection format. In this paper, we introduce and share results on a relatively new projection format called Rotated Sphere Projection (RSP). RSP uses two symmetric and perfectly continuous segments to represent sphere. It has a simple 3:2 aspect ratio, close proximity to sphere and a very simple mathematical representation that is same as Equirectangular Projection. Test results using JVET’s common testing conditions are also presented.
