The target split screen is selected by a user in at least one split screen of the display screen and is used for displaying the split screen of the current information stream to be displayed.
For example, a user selects a split screen with a resolution of 960 × 540 as a target split screen to display the current information stream to be displayed, and if the resolution of the current information stream to be displayed is 1920 × 1080, the resolution of the information stream to be displayed is compressed according to the resolution of the target split screen selected by the user, so that the information stream to be displayed can be normally played on the target split screen.
The technical scheme of the embodiment of the invention is that in response to the operation that a user clicks two target basic unit screens in a display screen, all basic unit screens in a minimum rectangle containing the two target basic unit screens are combined to obtain a new screen, the new screen and the basic unit screens which are not combined are used as split screens of the display screen, then the resolution corresponding to each split screen is determined according to the resolution of at least one physical screen, finally the resolution of an information stream to be displayed is adjusted according to the resolution of the target split screen selected by the user, and the adjusted information stream to be displayed is sent to the target split screens for display, on one hand, the display screen is split into a plurality of basic unit screens, the user can split the display screen by combining the basic unit screens, the split screen workload is reduced, on the other hand, the split screens can be flexibly performed according to the number of the information stream to be displayed, the utilization rate of the display screen is improved.
