Abstract
A method of decoding viewport bitstreams includes decoding first video content; transmitting, information about (i) a speed of a user's head movement while viewing the first video content and (ii) an available bandwidth; receiving a streaming bitstream that includes (i) a first coded video bitstream having a segment size defined for a viewport based on the available bandwidth and a head speed threshold corresponding to the speed of the user's head movement such that the segment size is inversely proportional to the speed of the user's head movement, the first coded video bitstream having a first resolution, and (ii) a second coded video bitstream having a second resolution corresponding to a background having a constant segment duration or size, the second resolution being lower than the first resolution; and rendering second video content using the first coded video bitstream and the second coded video bitstream.
