Abstract

The invention discloses a panoramic video playing method and device. The method comprises: receiving a panoramic video playing request of a player, the panoramic video playing request including user viewpoint position information; according to the user viewpoint position information, determining a video unit to be played, the vide unit being obtained by dividing the video frame of a panoramic video to be played in advance; and sending a vide unit determined to be played to a player in a video stream mode to solve the problem of a low use ratio of a transmission bandwidth in the present panorama video playing technology.

Description

technical field [0001] The present invention relates to the field of image processing, in particular to a method and device for playing panoramic video. Background technique [0002] At present, panoramic video refers to wide-angle video content that exceeds the general field of view. Usually, what we call circular / cylindrical 360-degree video provides a 360-degree field of view in the horizontal direction. [0003] There are many methods for panoramic video recording, which are usually divided into single-lens and multi-lens methods. High-quality video can be obtained with multiple lenses or multiple cameras, but the resulting video files are typically three to four times the size of normal video files, or more. This brings great challenges to video storage and network transmission, especially in the process of network transmission, panoramic video requires a large transmission bandwidth. [0004] Because the existing panoramic video playback technology compresses the vid...
