Addressable TV Ad Targeting via WLAN Scanning Clustering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In the addressable TV advertisement environment, there is a challenge in providing targeted advertisements to set-top boxes due to indiscriminate transmission of advertisement IDs when terminals access multiple WLANs, including external networks, and potential blockages in terminal configurations, which can prevent ID transmission even when the terminal is within the home.
Innovation Solution
A method and device for providing targeted advertisements by classifying scanning data from WLANs into monitored time periods, generating clustering data sets, and selecting the data set with the smallest data change amount to determine the advertisement execution condition, thereby ensuring accurate targeting and resource efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the terminal transmits advertisement ID when accessing any WLAN, then the advertisement ID can be transmitted to the server side, but the advertisement ID may be transmitted indiscriminately to external WLANs and the transmission may be blocked when the terminal configuration prevents access
Solution Approach 1:
The patent introduces WLAN scanning data as an intermediary element to determine terminal location. Instead of directly transmitting advertisement ID based on WLAN access alone, the system uses scanning data containing WLAN identifiers and signal strengths to infer whether the terminal is in the home environment, thereby mediating the transmission decision to prevent indiscriminate transmission while maintaining reliability
Solution Approach 2:
The patent performs preliminary WLAN scanning and clustering analysis before advertisement ID transmission. By pre-classifying scanning data into clusters representing different locations and identifying the cluster with the smallest data change amount (most stable location), the system determines advertisement execution conditions in advance, ensuring reliable transmission only when the terminal is confirmed to be at home
2Measurement precision
If the terminal continuously scans WLANs to determine location, then accurate location identification can be achieved, but unnecessary resource usage occurs
Solution Approach 1:
The patent applies partial action by performing WLAN scanning only to the extent necessary for location determination. Instead of continuous scanning, the system collects scanning data, classifies it into clusters, and selects the cluster with the smallest data change amount. This partial approach achieves sufficient location accuracy without excessive energy consumption from continuous scanning operations
Solution Approach 2:
The patent performs preliminary clustering classification of WLAN scanning data to identify stable location patterns before using this information for advertisement delivery. By pre-processing the scanning data into clustered groups representing different locations, the system establishes location identification criteria in advance, reducing the need for continuous scanning and thereby lowering energy consumption while maintaining measurement precision
3Loss of information
If advertisement ID transmission is performed through WLAN access, then the advertisement ID can be delivered to the server, but the transmission may be blocked when terminal configuration prevents WLAN access
Solution Approach 1:
The patent uses WLAN scanning data as an intermediary indicator of terminal location rather than relying solely on WLAN access for advertisement ID transmission. The scanning data (containing WLAN identifiers and signal strengths) serves as a mediator to infer home presence, allowing the system to determine advertisement execution conditions even when direct WLAN access is blocked by terminal configuration
Solution Approach 2:
The patent inverts the conventional approach by not using WLAN access itself as the trigger for advertisement ID transmission. Instead, it uses the absence or blockage of WLAN access combined with scanning data analysis to determine location. This inversion allows the system to adapt to terminal configurations that block WLAN access while still achieving complete advertisement ID delivery through alternative determination methods

AI summary
The present disclosure proposes a device for executing an advertisement service and a method for operating the same, for providing a targeted advertisement according to an advertisement execution condition determined for a terminal on the basis of scanning data obtained by scanning wireless local area networks (WLANs) (for example, Wi-Fi) in an addressable TV advertisement environment. The present disclosure also proposes a device for executing an advertisement service for providing a targeted advertisement for a combination of member terminals and visitor terminals located within a home in an addressable TV advertisement environment.
