Display System for Accurate Ad Cost Calculation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Large-sized displays inaccurately calculate advertising costs due to errors in measuring advertisement playing time, leading to unnecessary expenses for content providers.
Innovation Solution
A display system comprising a display device, a first server, and a second server that compares the content provided with the content captured by a photographing device to determine the actual display time and calculate advertising costs based on a specified rate of coincidence between the two.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If the large-sized display measures advertisement playing time based on metadata and log-on information, then the measurement process is simple and automated, but the measurement precision deteriorates because the display may consider time when advertisement is not actually displayed (due to defects or errors) as advertisement playing time
Solution Approach 1:
The patent introduces a photographing device as an intermediary to capture actual display content and a server as a mediator to compare captured content with transmitted advertisement content. This intermediary mechanism enables verification of actual display status, resolving the contradiction between automated measurement simplicity and measurement precision by adding a verification layer without completely manual intervention.
Solution Approach 2:
The patent implements a feedback mechanism where the photographing device captures actual display content and transmits it to the server, which then compares it with the advertisement content that was transmitted to the display. This feedback loop allows the system to detect discrepancies between intended and actual display, correcting measurement errors while maintaining automation through automated comparison and calculation processes.
2Productivity
If the large-sized display calculates advertising costs based on metadata without verification, then the calculation process is fast and automated, but the reliability deteriorates because advertising costs may increase unnecessarily when advertisements are not actually displayed due to display defects or data errors
Solution Approach 1:
The patent applies preliminary action by having the photographing device capture actual display content in advance and transmit it to the server before final cost calculation. The server then compares this pre-captured content with the advertisement content, allowing potential display errors to be detected and corrected before advertising costs are finalized, thus improving reliability while maintaining automated calculation speed.
Solution Approach 2:
The patent uses feedback by implementing a verification process where captured display content is fed back to the server for comparison with transmitted advertisement content. This feedback mechanism identifies discrepancies such as display defects or data errors, allowing the system to adjust advertising cost calculations to reflect actual display status, thereby improving reliability without significantly reducing calculation speed through automated comparison processes.

AI summary
A display system may include a display, a first server transmitting first content to the display device, a second server receiving the first content from the first server, and a camera transmitting second content obtained by capturing images on the display, to the second server. The second server may be configured to determine whether a rate at which the first content coincides with the second content is greater than or equal to a specified value, by comparing the first content with the second content. The second server measures a first time period during which a region of the captured images corresponding to the first content coincides with the second content at a rate which is greater than or equal to the specified value. Advertising costs are calculated based on the measured first time period.
