A content transmission and control system between multiple screens

Abstract

The invention discloses a multi-screen content transmission and control system. The transmission and control system includes a window content synthesis subsystem, a layout synthesis subsystem, a window scheduling subsystem and a window interaction control subsystem; the layout synthesis subsystem receives the window A certain amount of windows to be displayed sent by the content synthesis subsystem, according to the number of displayable screens, each screen size parameter, each size parameter of each window to be displayed and the minimum allowable resolution of the window image, limits the zoom ratio range of the window; The non-overlapping effect value, the complete display of windows on the screen and the maximum utilization rate of the screen are the constraints, and the final window layout is adjusted to obtain the final window layout; the window interactive control subsystem is used to interactively control the windows displayed on different screens by operating the main screen . The invention can schedule and manage the layout of the windows based on the contents of the windows, and can synthesize based on the original size of the contents of the windows, thereby obtaining better picture quality.

Description

technical field [0001] The invention relates to the technical field of multi-screen applications, in particular to a system for transmitting and controlling content between multiple screens. Background technique [0002] With the development of hardware technology, more and more devices support multiple screen displays. However, in terms of software, many applications simply display independent content on different screens on the basis of operating system support for multiple screens, or simply duplicate application windows on multiple screens. At present, there is no method capable of automatically arranging the layout in combination with the contents of the windows. [0003] In addition, the invention with the patent number CN201210148910.5 proposes a method, device and system for traversing display content between screens, and uses gestures to cut out a part of the main screen and display it on the secondary screen by using a frame selection area on the main screen .
