Omnidirectional videos are widely used in Virtual Reality applications. Omnidirectional videos are sphere in origin and need to be projected to a 2D-plane before coding and transmission. Common projection methods suffer from the overstretching in the polar areas which leads to the enormous decreasing of the omnidirectional video quality. In this paper, we proposed a novel representation based on pseudo-cylindrical projection. The representation is then reshaped and rearranged in the considering of several constraints including saving the pixel area and increasing viewing quality. The generation of our representation is formed as a multi dimension optimization problem. Our results across the test video sequences show significant coding gains over standard representations.
