Abstract: A method includes: displaying a first interface, where the first interface includes a first thumbnail of first video data, and the first video data includes a first transition special effect, and the first transition special effect is superimposed on a plurality of consecutive first video frames in the first video data; receiving a first operation performed by a user on the first thumbnail; displaying a second interface in response to the first operation, where the second interface includes a one-click blockbuster control; displaying a third interface after a second operation performed by the user on the one-click blockbuster control is received, where the third interface is used to display second video data.

Abstract: Provided is a control method applied to a screen projection scenario. The method includes: receiving first screen content and a target navigation function identifier sent by a mobile phone; generating, according to the target navigation function identifier, a collaboration window including a screen projection area and a navigation bar, where the navigation bar includes three virtual navigation keys; displaying the first screen content in the screen projection area; receiving a keyboard and mouse operation acting on the virtual navigation keys; generating a key instruction according to the keyboard and mouse operation, and sending the key instruction to the mobile phone, so that the mobile phone executes a navigation function according to the key instruction, and the mobile phone can adjust the first screen content to second screen content, and displaying the second screen content in the screen projection area.

Abstract: This application provides a window display method, a window switching method, an electronic device, and a system. The method is applied to multi-screen collaboration between a mobile phone and a PC, and a plurality of application interfaces of the mobile phone are displayed in a form of tabs in a multi-screen collaboration window. In the multi-screen collaboration process, a background of the mobile phone may obtain user operations, distinguish between operation objects according to the user operations, and then determine a running status of an application and a window display status, so as to obtain an operation result that better meets user's expectation. The method may further implement file sharing between the mobile phone and the PC and between different applications of the mobile phone.
