Abstract: A method for controlling virtual reality (VR) video playing and an apparatus are provided. In this method, a video server device renders a jump icon in a video image. When a user wants to perform video jump based on video content, a jump icon corresponding to a scene in which the user is interested may be selected to form an input. The video server obtains, based on the input of the user, a jump time of a jump target video corresponding to the jump icon, and plays the jump target video for the user from the jump time. The jump target video may be a video that is being played, or may be another video. According to the application, a video can be switched based on preferences of the user.

Abstract: A method and an apparatus for obtaining an extended depth of field image, and an electronic device are disclosed. The method includes: determining a target focal length range based on an initial focal length (101), where the target focal length range includes the initial focal length; obtaining a plurality of images of a photographed object for a plurality of focal lengths in the target focal length range (102); and registering and fusing, the plurality of images to obtain an extended depth of field image (103). The target focal length range of concern to a user is selected based on the initial focal length, so that there is no need to obtain images of all focal lengths of a lens, a quantity of obtained images and processing time of registration and fusion can be reduced.

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.
