Solution Overview

Problem

Existing media monitoring systems struggle to identify and credit media presentations that are not yet represented in the reference database, such as newly released content or regional broadcasts, due to mismatched signatures.

Innovation Solution

A system and method that collects and analyzes segments of unknown media signatures, stacks matching segments together, associates them with URLs to identify the media, and adds them to the reference database, using a matcher to facilitate meter-to-meter matching and media identification.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If traditional signature matching is used against a fixed reference database, then identification speed is maintained, but newly released or regional media content cannot be identified

Engineering Contradiction:
ImproveAbility to identify new media contentVSAvoidSignature matching accuracy
Core Design Contradiction:
Adaptability or versatilityVSMeasurement precision

Solution Approach 1:

The system performs preliminary actions by collecting and stacking unknown signature segments from multiple meters before attempting identification. This allows the system to build sufficient data about new media content before it can be matched against reference signatures, enabling identification of previously unknown content while maintaining accuracy through the stacking process that consolidates multiple observations

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent introduces an intermediary process between signature collection and identification: the unknown signature segment stacking mechanism. This intermediary layer allows unknown signatures to be aggregated and processed through multiple comparisons across different meters before being added to the reference database, serving as a bridge that enables new content identification while maintaining the integrity of the traditional matching system

Inventive Principle:
Principle #24Intermediary (Mediator)

2Measurement precision

If unknown signature segments are collected and stacked from multiple meters, then media identification accuracy improves, but processing time and system complexity increase

Engineering Contradiction:
ImproveMedia identification accuracyVSAvoidSignature processing system complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The system segments the signature matching process into distinct phases: collection of unknown signature segments, stacking of these segments from multiple meters, and subsequent identification attempts. This segmentation allows each component to be optimized independently and manages complexity by breaking down the overall process into manageable stages rather than attempting to solve the entire problem at once

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system performs partial actions by collecting and stacking only the necessary number of unknown signature segments required to achieve reliable identification, rather than processing all possible data. The stacking process continues until sufficient confidence is reached, avoiding excessive processing while maintaining high identification accuracy through targeted data aggregation

Inventive Principle:
Principle #16Partial or excessive action

3Reliability

If reference database is updated with new media signatures, then completeness of media monitoring improves, but database management complexity increases

Engineering Contradiction:
ImproveCompleteness of media monitoringVSAvoidDatabase management complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The system implements self-service by automatically adding verified unknown signature segments to the reference database without requiring manual intervention. Once unknown signatures are stacked and identified through the meter-to-meter matching process, they are automatically integrated into the reference database, enabling the system to self-expand its knowledge base while maintaining reliability and reducing operational complexity

Inventive Principle:
Principle #25Self-service

AI summary

Example methods, apparatus, systems and articles of manufacture are disclosed to facilitate meter to meter matching for media identification. Example apparatus disclosed herein include an unknown signature comparer, a stack counter, and a reference database updater. The unknown signature comparer is to select a candidate unknown signature segment meeting a threshold length from a set of unknown signature segments collected at a first audience measurement location, and compare individual signatures of the candidate unknown signature segment with a collection of unknown signature segments collected at a second audience measurement location. The stack counter is to count a number of times that the candidate unknown signature segment matches unknown signature segments in the collection, and identify the candidate unknown signature segment as a matched signature segment when the number of times meets a counter threshold. The reference database updater is to store the matched signature segment in a signature reference database.
