Non-Linear Media Source Detection Using Content Fingerprints

Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing media-monitoring systems face challenges in accurately determining the source of non-linear content presented on media-presentation devices, particularly when the last mile of content delivery does not traverse a local area network, making it difficult to identify which streaming-media service provided the content.

Innovation Solution

A computing system deduces the source of non-linear content by finding an intersection between a set of available streaming-media services and a set of services known to offer the identified content, using panelist subscription data and content catalog information, and considers factors like commercial breaks to enhance accuracy.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If traditional media-monitoring methods are used to track linear broadcast content, then content identification is straightforward through watermarking and timestamping, but the system cannot accurately identify the source of non-linear on-demand streaming content

Engineering Contradiction:

Improvecontent source identification accuracyVSAvoidcontent type coverage

Core Design Contradiction:

Measurement precisionVSAdaptability or versatility

Solution Approach 1:

The patent segments the content identification process into two distinct pathways: one for linear broadcast content using traditional watermarking/timestamping methods, and another for non-linear on-demand content using fingerprint matching against a catalog database. This segmentation allows each pathway to be optimized for its specific content type, resolving the contradiction between measurement precision for identified content and adaptability to different content delivery models.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent introduces a catalog database as an intermediary component that stores fingerprint data for on-demand content. The presentation meter compares extracted fingerprints against this catalog to identify content and determine its source. This intermediary enables accurate source identification for non-linear content without requiring modifications to the streaming delivery mechanism itself.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Measurement precision

If the system monitors only content that traverses the local area network, then source identification is simplified, but content delivered through other paths (e.g., DOCSIS, satellite) cannot be tracked

Engineering Contradiction:

Improvesource identification capabilityVSAvoidmonitoring system architecture

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The patent implements self-service monitoring where the presentation meter at the panelist site performs content identification and source determination autonomously by extracting fingerprints from the presented content and matching them against the catalog database. This eliminates the need for external monitoring infrastructure for each content delivery path, allowing the system to track content regardless of whether it traverses the LAN, DOCSIS, satellite, or other delivery mechanisms.

Inventive Principle:

Principle #25Self-service

3Adaptability or versatility

If multiple streaming-media services offer the same content, then content availability increases, but determining which specific service provided the content becomes ambiguous

Engineering Contradiction:

Improvecontent availabilityVSAvoidsource attribution accuracy

Core Design Contradiction:

Adaptability or versatilityVSMeasurement precision

Solution Approach 1:

The patent performs preliminary action by pre-populating a catalog database with fingerprint data and metadata for content from multiple streaming-media services before monitoring begins. When content is presented, the system queries this pre-prepared catalog to identify both the content and its source service. This preliminary preparation enables accurate source attribution even when multiple services offer the same content, as the catalog contains service-specific identifiers.

AI summary

A method and system for media-exposure monitoring. An example method includes a computing system receiving digital query signature data representing a media content item presented at a panelist site. Further, the method includes the computing system identifying the media content item, with the identifying being based on matching of the received digital query signature data with reference signature data. Still further, the method includes the computing system determining a streaming-media service that streamed the identified media content item to the panelist site for presentation, with the determining of the streaming-media service including finding an intersection of (i) a first set of one or more streaming-media services known to offer streaming of the media content item and (ii) a second set of one or more streaming-media services to which the panelist site subscribes.
