Display Content Handoff to User Terminals Outside Viewing Range
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display apparatuses cannot provide content to users outside their installed space, limiting viewing to a specific area.
Innovation Solution
A display apparatus connected to a user terminal determines the user's position and, if outside the viewing area, outputs content through the terminal using communication signals and image data to ensure seamless content delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the display apparatus provides content only within its installed space, then the content delivery is simple and reliable, but the user cannot view content when outside the viewing area
Solution Approach 1:
The patent introduces a user terminal as an intermediary device to relay content delivery between the display apparatus and the user. When the user moves outside the viewing area, the terminal receives content data or screen data from the display apparatus and outputs it locally, enabling continuous content access without requiring the user to remain within the display apparatus's physical viewing space
Solution Approach 2:
The system segments the content delivery function into two parts: the display apparatus generates and transmits content data, while the user terminal handles local output and positioning. This segmentation allows the content delivery system to extend beyond the display apparatus's fixed location while maintaining functional simplicity through clear division of responsibilities
2Ease of operation
If the display apparatus tracks user position to enable seamless content delivery, then the user experience is improved, but the device complexity increases
Solution Approach 1:
The user terminal performs self-service by autonomously determining its own position relative to the display apparatus using communication signal characteristics (RSSI, RTT) and automatically switching content output between the display apparatus and itself based on position. This eliminates the need for complex external tracking systems while maintaining seamless content delivery
Solution Approach 2:
The system uses feedback from communication signals (RSSI, RTT) to continuously monitor the user's position relative to the display apparatus. Based on this feedback, the display apparatus or terminal automatically adjusts content delivery mode, ensuring seamless transition without requiring complex manual intervention or additional tracking hardware
3Adaptability or versatility
If the content is transmitted to the terminal when the user is outside the viewing area, then the user can view content remotely, but the content quality may be affected by transmission distance
Solution Approach 1:
The system transmits only essential content data or screen data to the terminal when the user is outside the viewing area, rather than transmitting full-resolution video continuously. This partial transmission approach maintains acceptable content quality while reducing transmission demands and improving reliability over distance
Solution Approach 2:
The system dynamically changes transmission parameters based on user position. When the user is within the viewing area, direct display is used with high quality. When outside, the system switches to terminal output with adjusted data transmission modes, maintaining content reliability across varying distances by adapting transmission characteristics to the specific scenario

AI summary
An embodiment according to the present disclosure provides a display apparatus including a display, an audio output interface, a memory, a communication interface configured to connect to a terminal of a user, and a processor configured to output, via at least one of the display or the audio output interface, content stored in the memory or received through the communication interface, determine a position of the terminal to which the communication interface is connected, determine whether the position of the terminal is outside of a viewing area, and based on determining that the position of the terminal is outside of the viewing area, output the content to the terminal.
