Compression of 16K Video for Mobile VR Playback Over 4K Streams
Mobile virtual reality headset devices are currently constrained to playing back 4K video streams for hardware, network, and performance reasons. This strongly limits the quality of 360° videos over 4K streams; which in turn translates to insufficient resolution for virtual reality video playback. Spherical stereo virtual reality videos can be currently captured at 8K and 16K resolutions, with 8K being the minimal resolution for an acceptable quality video playback experience. In this paper, we present a novel technique that uses object tracking to compress 16K spherical stereo videos captured by a still camera into a format that can be streamed over 4K channels while maintaining the 16K video resolution for typical video captures.
