摘要：
A virtual reality (VR) client device may be configured to act as part of a split rendering system. The VR client device may include a memory configured to store video data and one or more processors implemented in circuitry and configured to: determine pose information representing a current pose of a user of the device associated with a current picture of the video data and a previous pose of the user of the device associated with a reference picture of the video data; obtain a warped version of the reference picture according to differences between the current pose and the previous pose; and code one or more blocks of the current picture using the warped version of the reference picture.
