Drag and Drop Content Management for Digital TV Interfaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing content playing methods for digital TV and IPTV systems lack efficient user interfaces for simultaneously displaying and managing multiple content streams, leading to user inconvenience in navigating and playing various content types such as real-time broadcasts, on-demand services, and games.
Innovation Solution
A content playing method utilizing a drag and drop operation on a graphical user interface, allowing users to select and play multiple content streams simultaneously by moving and dropping content information on a screen, with the system determining main and sub-screen displays based on drop location, enabling efficient content management and playback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional content playing methods are used, then system simplicity is maintained, but user convenience and content management efficiency deteriorate
Solution Approach 1:
The patent introduces a drag-and-drop graphical user interface as an intermediary layer between the user and the content playing system. This interface allows users to visually select and arrange multiple content streams (broadcasts, on-demand content, games) on a virtual screen layout, which then translates user actions into system commands. The intermediary GUI simplifies complex multi-content management operations into intuitive drag-and-drop gestures, improving ease of operation without requiring changes to the underlying system architecture.
2Adaptability or versatility
If multiple content streams are displayed simultaneously, then content management capability is improved, but interface complexity increases
Solution Approach 1:
The patent segments the display area into multiple independent screen regions (main screen, sub-screens) that can independently display different content streams. Each content type (broadcast, on-demand, game) is assigned to a separate segment, allowing simultaneous display and independent control. The drag-and-drop interface enables users to divide the screen into these segments by dragging content icons to desired positions, creating a segmented layout that manages multiple content streams without presenting a monolithic complex interface.
Solution Approach 2:
The patent adds a spatial dimension to content selection and arrangement by allowing users to drag content icons to different positions on the screen to create main and sub-screen displays. This spatial arrangement dimension provides an intuitive way to manage multiple content streams - users can visually organize content in a 2D space rather than navigating through complex menus or settings, thereby improving content management capability while keeping the interface relatively simple.
3Productivity
If drag and drop operation is implemented, then user interaction efficiency is improved, but operational complexity increases
Solution Approach 1:
The drag-and-drop interface enables users to self-configure their own content layout by dragging content icons to desired screen positions. The system automatically interprets the drag-and-drop action, determines the intended main and sub-screen assignments based on drop location, and configures the display accordingly without requiring user knowledge of system settings or commands. This self-service approach improves user interaction efficiency while maintaining operational simplicity.
Data Source
AI summary
A method for playing contents is provided. In the method, information corresponding, respectively, to a plurality of contents may be displayed, and a drag and drop operation related to first contents information and second contents information among the displayed contents information may be received. Thereafter, the first contents and the second contents may be played.
