Abstract
A video playing method, a device, and a system are provided. The method includes: receiving, by a VR device, a first-resolution VR video stream of a first viewing angle and a second-resolution VR video stream of a full viewing angle that are sent by a server, where the first resolution is greater than the second resolution; playing an image of the first viewing angle by using the VR video stream of the first viewing angle; when determining that the viewing angle changes, playing an image of a current viewing angle by using the first or both of the VR video stream of the full viewing angle and the VR video stream of the first viewing angle; sending, to the server, viewing angle information that carries a parameter for indicating a changed-to second viewing angle; receiving a first-resolution VR video stream of the second viewing angle sent by the server.
