Abstract
A system and method for effectuating optimized 360° immersive video viewing experience. A media input stream is coded into a plurality of phase-encoded bitstreams in multiple bitrate representations with varying video qualities. Each phase-encoded bitstream that belongs to a particular bitrate representation includes a number (N) of frames with a specific GOP structure having a GOP size (p), wherein the plurality of phase-encoded bitstreams equals the GOP size. For each pphase-encoded bitstream, N frames are encoded as follows: at least a first frame is encoded as an I-frame; and a frame at a frame position i, for 2≤i≤N, that satisfies {i Mod (GOP size)}=p is encoded as an X-frame that has a slice header of a P-frame and includes blocks of only intra-coded data, otherwise, that frame is encoded as a P-frame having blocks of predictive-coded data (P-blocks) with a P-slice header.
