Multi-screen Control via Composition Window for Smart TV
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current solutions for interconnecting smart mobile phones with smart televisions require development of control applications and synchronize content based on whole screen display, limiting multi-window functionality and remote control capabilities.
Innovation Solution
A multi-screen control method and device that composites application windows, transmits them to a smart terminal, receives user input, and adjusts interfaces based on display attributes, allowing for simultaneous control and display of multiple applications across different devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If whole screen display synchronization is used for smart television control, then content can be displayed on large screen, but multi-window functionality is limited
Solution Approach 1:
The patent segments the display content by compositing multiple application windows into a single image that preserves individual window boundaries. This allows the television to display multiple application windows simultaneously in their original positions and sizes, enabling multi-window functionality while utilizing the large display area.
2Ease of operation
If remote control functionality is added to smart television, then user convenience is improved, but control complexity increases
Solution Approach 1:
The patent captures the entire screen content as an image and transmits it to the television, creating a visual copy of the mobile device interface. This allows users to see and interact with application windows on the television screen while the actual control logic remains on the mobile device, simplifying the television's control complexity.
3Productivity
If multiple applications are displayed simultaneously, then user productivity is improved, but screen space management becomes complex
Solution Approach 1:
The patent moves the multi-application display from the mobile device's limited screen to the television's large screen, utilizing the additional display dimension. The mobile device continues to execute multiple applications, but their visual representation is transferred to the television, simplifying screen space management on the mobile device while enabling multi-application productivity.
Data Source
AI summary
A method of controlling an application of a smart device, by the smart device, is provided. The method includes generating a composition window by compositing windows of applications of the smart device, and transmitting the composition window to a smart terminal on which the composition window is displayed. The method further includes receiving, from the smart terminal, information of a user input in the smart terminal with respect to the displayed composition window, and controlling and displaying at least one among the applications based on the received information of the user input.
