    Abstract: A method includes receiving a first video stream at a playback device, the first video stream having a first quality, receiving at least two second video streams at the playback device, the at least two second video streams each corresponding to a portion of the first video stream, the at least two second video streams having a second quality, the second quality being a higher quality as compared to the first quality, playing back the first video stream at the playback device, selecting a third video stream from the at least two second video streams based on a view perspective of a user of the playback device, and playing back the third video stream together with the first video stream at the playback device.

    Abstract translation: 一种方法包括在回放设备处接收第一视频流，第一视频流具有第一质量，在回放设备处接收至少两个第二视频流，所述至少两个第二视频流分别对应于第一视频的一部分 流，所述至少两个第二视频流具有第二质量，所述第二质量与所述第一质量相比更高质量，在所述播放设备处回放所述第一视频流，从所述至少两秒中选择第三视频流 基于播放设备的用户的视角透视的视频流，以及在播放设备处与第一视频流一起播放第三视频流。

    Abstract: In a general aspect, a method includes determining a tile position in a frame of a spherical video based on a view perspective, selecting a portion of the frame of the spherical video as a two dimensional tile based on the tile position, encoding the two dimensional tile at a first quality, mapping the frame of the spherical video to a two dimensional representation of the spherical video based on a two dimensional projection algorithm, and encoding the two dimensional representation of the spherical video at a second quality.

    Abstract: Systems and methods are described for defining a set of images based on captured images, receiving a viewing direction associated with a user of a virtual reality (VR) head mounted display, receiving an indication of a change in the viewing direction. The methods further include configuring, a re-projection of a portion of the set of images, the re-projection based at least in part on the changed viewing direction and a field of view associated with the captured images, and converting the portion from a spherical perspective projection into a planar perspective projection, rendering by the computing device and for display in the VR head mounted display, an updated view based on the re-projection, the updated view configured to correct distortion and provide stereo parallax in the portion, and providing, to the head mounted display, the updated view including a stereo panoramic scene corresponding to the changed viewing direction.
