TV Viewership Correlation via Separate Login Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Accurately measuring TV viewership is challenging due to the difficulty in tracking individual viewership status, as participants may leave the room or temporarily stop watching, leading to false positive data samples with existing TV metering devices.
Innovation Solution
A system that receives TV broadcast information from a metering device and TV panelist status information from a separate login/logout device, correlating both with timestamps to determine the viewership status accurately, allowing panelists to log in and out from different devices, reducing the need for direct interaction with the metering device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a TV metering device is provided to every household participant, then TV viewership monitoring capability is improved, but cost and device complexity increase
Solution Approach 1:
The patent extracts the login/logout tracking function from the TV metering device and places it in a separate login/logout device. This allows the TV metering device to focus solely on monitoring TV status while the login/logout device handles participant status tracking, reducing the complexity of the original integrated device while maintaining monitoring capability.
Solution Approach 2:
The system is divided into two separate functional components: a TV metering device for monitoring TV broadcast status and a login/logout device for tracking participant presence. This segmentation allows each device to be simpler and more specialized, reducing overall system complexity while improving reliability through dedicated functions.
2Measurement precision
If participants directly interact with the metering device to indicate viewing status, then measurement accuracy is improved, but ease of operation deteriorates
Solution Approach 1:
The login/logout device serves as an intermediary between the participant and the TV metering device. Participants interact with the login/logout device to indicate their viewing status, which then communicates with the metering device. This intermediary simplifies the user interface and makes operation easier while maintaining accurate measurement through the coordinated system.
3Productivity
If participants remain logged in continuously, then data collection is simplified, but measurement precision deteriorates due to false positives
Solution Approach 1:
The system implements feedback mechanisms where the login/logout device continuously monitors participant status and communicates with the TV metering device. When a participant logs out or their status changes, the system receives feedback and updates the viewing record accordingly. This feedback loop maintains data collection efficiency while preventing false positives by ensuring continuous status verification.
Data Source
AI summary
A computer system for determining TV viewership information for one or more TV panelists is provided, the computer system having memory to store programs and one or more processors for executing the one or more programs. The programs include instructions for: receiving TV broadcast information from a TV metering device, wherein the TV broadcast information identifies a current status of a TV in a household and an associated timestamp; receiving TV panelist status information from a first login/logout device that is different from the TV metering device, wherein the TV panelist status information identifies a viewership status of the TV panelist and an associated timestamp; and correlating the TV broadcast information with the TV panelist status information in accordance with their respective timestamps to determine a relationship between the TV panelist and a respective TV program currently broadcasted by the TV in the household.
