Abstract

The invention relates to a live broadcast method and device of panoramic video. The method includes: acquiring live broadcast data flow of panoramic video; acquiring corresponding relationship of broadcast time point of panoramic video played by a first terminal and coordinate information; pushing the live broadcast data flow and the corresponding relationship to a second terminal to enable the second terminal to broadcast the live broadcast data flow according to the corresponding relationship. The corresponding relationship of the broadcast time point of the panoramic video broadcast by the first terminal and the coordinate information is acquired through a server, the live broadcast data flow and the corresponding relationship are pushed to the second terminal to enable the second terminal to broadcast the live broadcast data flow according to the corresponding relationship, coordinates of the second terminal for watching the panoramic video can keep pace with those of the first terminal through the live broadcast method and device of the panoramic video, and accordingly users corresponding to the second terminal can understand explained content from the first terminal easily, and experience of users watching the panoramic video can be improved.

Description
