Abstract

The invention provides a video playing method and system and equipment. The method comprises the steps that the VR equipment receives a first-resolution and first-view VR video stream sent by a serverand a second-resolution and full-view VR video stream continuously sent by the server, wherein the first resolution is higher than the second resolution; pictures of the first view are played by adopting the first-view VR video stream; when it is determined that the view changes, pictures of the current view are played by adopting the first or both two of the full-view VR video stream and the first-view VR video stream; view information carrying a parameter for indicating to change to the second view is sent to the server; a first-resolution and second-view VR video stream sent by the serveris received; and pictures of the second view are played by adopting the second-view VR video stream. According to the scheme, the problems that a network VR service is wide in occupied bandwidth and long in delay are solved simultaneously, the storage overhead of the server can be reduced, and traffic burst can be avoided.

Description

technical field [0001] The embodiments of the present application relate to the technical field of virtual reality (VR), and in particular, to a video playing method, device, and system. Background technique [0002] VR technology is a computer simulation technology that can create and experience a virtual world. VR technology can provide users with multi-sensory immersive experiences such as vision, hearing, and touch. Network VR technology refers to the technology that provides VR services to users through the network. The service server deployed in the network transmits the VR video stream to the VR device through the network, and the VR device plays the received VR video stream. [0003] Currently, the following two solutions are usually used to transmit and play VR video streams. In the first solution, the server sends a 360-degree panoramic VR video stream to the VR device, and the VR device uses the 360-degree panoramic VR video stream to play a picture correspondin...
