TV Audience Tag Correlating Audio and Heartbeat Signals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current TV viewership measurement systems face challenges in accurately determining individual viewing activities due to false positives and false negatives, where viewers may be incorrectly recorded as watching a program or not recorded at all, leading to inaccurate data.
Innovation Solution
A method and system using a master device adjacent to the TV and a tag carried by the individual to detect audio signals and heartbeat signals, generating TV broadcast records and audience records, which are then correlated to determine the TV programs watched, thereby reducing false positives and false negatives.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual logging by viewers is used to document viewing activities, then the system can capture viewing data, but false positives and false negatives occur leading to inaccurate measurement
Solution Approach 1:
The patent introduces an intermediary system consisting of audio fingerprinting technology and location tracking devices that automatically verify viewing activities. The audio fingerprinting system acts as a mediator between the TV content and the logging system, while location tracking devices serve as intermediaries between the viewer and the measurement system, providing objective verification of actual viewing behavior.
Solution Approach 2:
The patent replaces the manual mechanical logging system with an automated electronic measurement system. Instead of relying on viewers manually recording their viewing activities, the system uses automatic audio detection, location tracking, and data correlation to determine viewing behavior, eliminating human error and intentional misinformation.
2Measurement precision
If automated monitoring is implemented to track viewing activities, then measurement accuracy improves, but system complexity increases
Solution Approach 1:
The patent employs universal components that serve multiple functions. The audio fingerprinting system not only identifies TV programs but also verifies viewing timing and duration. The location tracking devices not only determine viewer presence but also track movement patterns. This multi-functionality reduces the need for separate specialized devices, thereby managing system complexity.
Solution Approach 2:
The system is designed to be self-serve by automatically collecting, processing, and correlating data without requiring manual intervention. The automated correlation between audio fingerprints and location data occurs without human input, and the system self-adjusts to account for various viewing scenarios, reducing the operational complexity despite the sophisticated technology involved.
3Reliability
If location tracking is used to verify viewer presence, then false positives are reduced, but privacy concerns and system complexity increase
Solution Approach 1:
The patent extracts only the essential location information needed to determine viewing presence without capturing detailed personal data. The system extracts binary presence/absence data rather than comprehensive location histories, thereby reducing privacy intrusiveness and simplifying data processing requirements while maintaining measurement reliability.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This approach provides accurate TV viewership data by tracking individual locations relative to the TV and correlating audio fingerprints with viewing activities, ensuring precise measurement of TV programs watched, thus enhancing the reliability of viewership ratings.
Implementation Method 1
detecting a plurality of audio signals from the TV
Implementation Method 2
detecting a plurality of heartbeat signals from the tag

AI summary
A TV audience survey system for determining the TV viewing activities of a plurality of individuals in a household includes a master device and multiple tags, each tag assigned to an individual. After an individual logs into the system and starts watching the TV, the master device communicates with the corresponding tag repeatedly to accumulate data representing the individual's TV viewing activities. Such data can be used to determine when the individual stops watching the TV for an extended period of time without logging out of the system and when the household member remains watching the TV after logging or being logged out of the system. The master device then reports the accumulated data to a remote server, which uses the data to determine whether the individual complies with the logging protocol defined by the TV audience survey system and update the TV viewership data associated with this household.
