Enhanced latency-adaptive viewport prediction for viewport-dependent content streaming

Abstract

This disclosure describes systems, methods, and devices related to latency-adaptive viewport prediction for use in viewport-dependent content streaming. A method may include identifying, by a virtual reality (VR) or augmented reality (AR) device, first viewport data used by and received from a display device; generating a first estimated compensation latency based on at least one of a first network latency and by the processing circuitry, from among multiple candidate viewport prediction models each using a different respective time interval, a first viewport prediction model based on a comparison of the first estimated compensation latency to a first time interval used by the first viewport prediction model; generating, using the first viewport prediction model and the first viewport data, a first viewport prediction; and selecting, based on the first viewport prediction, a first content tile for rendering by the display device.
