Abstract
A video server is configured to convert frame data of a spherical image to frame data of a equirectangular image such that a first area corresponding to a field of view received from a client device is a middle area of the equirectangular image. The video server is further configured to scale the first area at a first resolution, scale a second area of the equirectangular image adjacent to the first area at a second resolution smaller than the first resolution, scale a third area of the equirectangular image that is adjacent to the first area and is not adjacent to the second area, at a third resolution smaller than the first resolution, and rearrange the scaled first area, second area and third area such that the scaled second area and the scaled third area are adjacent to each other, to generate reformatted equirectangular image frame data to be encoded.
