VR streaming media playing method and device based on visual angle

Abstract

The invention discloses a VR streaming media playing method and device based on a visual angle. The method comprises the steps: carrying out the coding of a plurality of video images through a VR panoramic video hierarchical coding technology based on a visual angle slice; expanding the VR panoramic video streaming media protocol of the visual angle slice based on an HLS protocol, and transmittinga corresponding target video picture according to the user visual area; splicing and restoring the video streams corresponding to the visual angle slices into a full-frame video picture, and finallyrendering the full-frame video picture to VR display equipment. By adoption of the VR streaming media playing method based on the visual angle, the VR panoramic video transmission bandwidth can be greatly reduced, the VR panoramic video can be quickly played in the existing network, meanwhile, the decoding scale requirement of a user side is reduced, VR equipment only supporting 4K decoding can have the 8K VR panoramic video decoding capability, and a VR panoramic video picture with higher quality can be obtained in the current mainstream VR equipment.

Description

technical field [0001] Embodiments of the present invention relate to the field of VR streaming media data processing, in particular to a viewing angle-based VR streaming media playback method and device, and also to an electronic device and a computer-readable storage medium. Background technique [0002] At present, VR panoramic video usually uses traditional video coding technology to uniformly encode and transmit the 360-degree full-frame picture, and finally decodes and renders the entire picture at the user end. However, since VR panoramic videos are 360-degree omnidirectional video content, in order to ensure the comfort of users watching movies, videos generally use 4K or 8K resolution, and the encoding quality is also relatively high, which will bring problems in practical applications. Come a lot of questions. For example: the transmission video bit rate is very high, the video bit rate of general picture quality exceeds 30Mbps, and the bit rate of high-quality vi...
