Abstract: A video transmission method includes that a terminal sends first field of view information to a server through a first link based on a first period. The server receives the first field of view information from the terminal through the first link based on the first period. After determining, based on a second period, that the first field of view information is latest field of view information, the server obtains data of a first frame of image corresponding to the first field of view information, and sends the data of the first frame of image to the terminal through a second link. The terminal receives the data of the first frame of image from the server through the second link based on the second period.
