Multi-User Display Content Sharing With Visual Playback States
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for sharing content among multiple users are inconvenient and lack features that enhance the experience of content sharing, particularly when users need to connect their devices individually to a display apparatus.
Innovation Solution
A display apparatus and user terminals that allow multiple users to connect and share content through a user interface (UI) with distinguishable items and visual effects, controlled by a controller to reflect user inputs, including color assignment, visualizers, and timers for content reproduction based on user requests.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple users connect their user terminals to the display apparatus one by one to share content, then content sharing among multiple users is enabled, but the operation convenience deteriorates due to the need for sequential connection and individual device pairing
Solution Approach 1:
The patent merges multiple user terminal connections into a single group session. Instead of requiring individual pairing between each user terminal and the display apparatus, the system creates a group where multiple user terminals can connect simultaneously to the display apparatus through a unified interface, enabling concurrent content sharing without sequential connection steps
Solution Approach 2:
The display apparatus is enhanced with multi-functionality to serve as a central hub that can simultaneously manage multiple user terminals, display multiple content items, and coordinate group interactions. The controller is configured to handle diverse operations including receiving inputs from multiple users, managing content selection, and coordinating reproduction control states across all connected devices
2Device complexity
If the display apparatus provides basic content display functionality, then device complexity is minimized, but the user experience deteriorates due to lack of interactive features for multiple users
Solution Approach 1:
The user interface is designed to be dynamic and adaptive based on the number of connected user terminals and their input states. The controller automatically adjusts the display to show different information according to the current group state, such as displaying reproduction control states when content is being played, showing content selection interfaces when no content is active, and dynamically updating visual feedback based on which user terminal is currently receiving input
Solution Approach 2:
The system implements comprehensive feedback mechanisms where the display apparatus provides real-time visual feedback to user terminals about the current state of content reproduction, which user is currently controlling, and what actions are available. The controller monitors inputs from all user terminals and provides appropriate feedback through the display interface, enabling users to understand the system state and available interactions
3Loss of information
If the display apparatus displays all content items from multiple users simultaneously, then complete information is provided, but the display area requirement increases beyond available screen space
Solution Approach 1:
The display interface segments content information into different functional areas: a main content display area showing the currently selected content item, a sidebar or overlay area showing thumbnails or information about other available content items from different users, and a control area showing reproduction status. This segmentation allows complete information to be accessible while maintaining a clean, uncluttered main display area
Solution Approach 2:
The system uses multiple visual dimensions and layers to display content information. Instead of trying to show all content items in a single flat list, the interface uses overlapping layers, different display depths, and spatial arrangements where primary content is displayed prominently in the foreground while secondary content items are displayed in the background or in collapsible panels, effectively utilizing the display space across multiple visual dimensions

AI summary
A display apparatus includes a display; a communicator configured to communicate with a plurality of external apparatuses, which respectively provide a plurality of contents; and a processor. The processor is configured to: based on receiving information relating to contents among the plurality of contents from external apparatuses, respectively, through the communicator, identify the external apparatuses that transmitted the information, among the plurality of external apparatuses, control the display to display a UI including the contents respectively received from the identified external apparatuses, and control the display to display, on the UI, reproduction states of the contents to be visually distinguishable according to states of inputs of users of the received contents, the inputs being received through the identified external apparatuses, respectively.
