Abstract

The invention provides a video transmission method, a server, a VR playing terminal and a computer readable storage medium. The method comprises the following steps: predicting second position information of the VR playing terminal within a set time length according to first position information of the virtual reality VR playing terminal; and when a compressed video of a view angle corresponding to the second position information is sent to the VR playing terminal, when a sharing instruction sent by the VR playing terminal is received, sending the compressed video to other video playing terminals, so that the other video playing terminals pay the compressed video. By adoption of the video transmission method, the wireless transmission of VR videos or AR videos is achieved, and the constraints of the users by the cables caused by wired transmission are effectively avoided; and the VR videos or AR videos played by the VR player are shared to the other video playing terminals for playing,and thus effectively improving the user experience.

Description

technical field [0001] The present invention relates to the field of virtual reality technology, in particular to a video transmission method, a server, a VR playback terminal and a computer-readable storage medium. Background technique [0002] With the development of various technologies such as computer graphics, man-machine interface technology, multimedia technology, sensing technology and network technology, a computer simulation system for creating and experiencing the virtual world, the simulation system uses a computer to generate a simulation environment and integrates multiple The integration of source information and allowing users to participate in it is an interactive 3D dynamic view and system simulation of physical behavior, allowing users to immerse themselves in the simulated environment.
