Display Controller Spatial Multiplexing for Ad-Broadcast Overlap
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image display devices face challenges in simultaneously outputting advertisement and broadcast contents without interrupting the advertisement when the broadcast time arrives before the completion of advertisement content output, due to network instability or signal processing delays.
Innovation Solution
An image display device equipped with a network interface, broadcast reception unit, storage, and a controller that receives personal advertisement signals and broadcast signals, calculates the end time of advertisement contents, and determines whether the start time of broadcast contents precedes the end time of advertisements, allowing simultaneous output of both on different areas of the display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the image display device outputs advertisement contents continuously, then the advertisement output is maintained, but the broadcast contents cannot be output when the broadcast time arrives before advertisement completion
Solution Approach 1:
The display area is divided into multiple regions: a first display area for broadcast contents and a second display area for advertisement contents. This segmentation allows both types of contents to be displayed simultaneously without interfering with each other, resolving the contradiction between maintaining advertisement continuity and enabling broadcast output.
Solution Approach 2:
The patent transitions from temporal multiplexing (outputting one content type at a time) to spatial multiplexing (outputting both content types simultaneously in different areas). This dimensional change from time-based to space-based resource allocation enables both advertisement continuity and broadcast accessibility.
2Adaptability or versatility
If the image display device stops advertisement output to make room for broadcast contents, then the broadcast can be displayed, but the advertisement output is interrupted
Solution Approach 1:
By segmenting the display into separate areas for broadcast and advertisement contents, the system can accommodate both content types simultaneously without requiring one to yield to the other, eliminating the need to interrupt advertisements for broadcast display.
Solution Approach 2:
The patent merges the output of broadcast contents and advertisement contents by displaying them simultaneously in different display areas. This combining approach allows both content streams to proceed without interruption, resolving the contradiction between broadcast accessibility and advertisement continuity.
3Device complexity
If the image display device uses single-area display for contents output, then the display is simple, but cannot simultaneously show both advertisement and broadcast contents
Solution Approach 1:
The display area is segmented into a first display area for broadcast contents and a second display area for advertisement contents. This segmentation enables simultaneous output of both content types while maintaining a relatively simple overall display architecture, balancing complexity and functionality.
Solution Approach 2:
The patent introduces spatial dimensionality to the display output, transitioning from single-area sequential output to multi-area simultaneous output. This dimensional expansion enables the display to handle multiple content streams without significantly increasing system complexity.

AI summary
The present invention relates to an image display device and an operation method thereof. The image display device, according to one embodiment of the present invention, comprises: a display; a network interface unit for carrying out communication with an external server via a network; a broadcast receiving unit for receiving a broadcast signal; a storage unit; and a control unit. The control unit: receives a personalized advertisement signal including advertisement content via at least one among the network interface unit and the broadcast receiving unit; outputs the advertisement content through the full area of the display; receives a broadcast signal including broadcast content via at least one among the network interface unit and the broadcast receiving unit; calculates the ending time of the advertisement content; determines whether the starting time of the broadcast content is before the ending time of the advertisement content; and if the starting time of the broadcast content is before the ending time of the advertisement content, may output the broadcast content through a first area in the full area of the display and output the advertisement content through a second area in the full area of the display, starting from the starting time of the broadcast content. Other various embodiments are possible.
