Abstract: A projection method and a terminal device, including responding, by a transmit end, to a screen projection instruction, obtaining a real-time interface of an application program on which screen projection is to be performed and device information of one or more receive ends, obtaining a user experience score of each receive end of the one or more receive ends by scoring a visual effect, sound effect, and interaction complexity of each receive end based on the device information, obtaining, based on the user experience score, first data on which screen projection is to be performed and that is at least one of a video stream, an audio stream, or a user interface control, obtaining a control layout file of the user interface control in response to the first data having the user interface control, and sending, to a corresponding receive end, the first data and the control layout file.

Abstract: A video playing method, a device, and a system are provided. The method includes: receiving, by a VR device, a first-resolution VR video stream of a first viewing angle and a second-resolution VR video stream of a full viewing angle that are sent by a server, where the first resolution is greater than the second resolution; playing an image of the first viewing angle by using the VR video stream of the first viewing angle; when determining that the viewing angle changes, playing an image of a current viewing angle by using the first or both of the VR video stream of the full viewing angle and the VR video stream of the first viewing angle; sending, to the server, viewing angle information that carries a parameter for indicating a changed-to second viewing angle; receiving a first-resolution VR video stream of the second viewing angle sent by the server.

Abstract: An object drag method includes a first terminal that displays an object on a display of the first terminal. The first terminal receives a drag operation from a user. The drag operation initiates a drag for the object. The first terminal displays, on the display of the first terminal in response to the drag operation, an animation in which the object moves with the drag operation. The first terminal sends drag data to a second terminal after determining that a drag intent of the user is a cross-device drag. The drag data enables the second terminal to display the object on a display of the second terminal.
