Streaming Media Reference Signature Generation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing pace of new media releases on streaming platforms delays audience measurement entities in measuring audience reception due to the lack of reference signatures.
Innovation Solution
Generating reference audio signatures by collecting media metadata and audio signatures during media playback, and associating them to create reference signatures that can be stored in a database for future use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If reference media is obtained from providers, then reference signatures can be generated, but the process is delayed due to the increasing pace of new media releases
Solution Approach 1:
The system performs preliminary action by capturing audio during media playback and generating candidate reference signatures in advance, before the official reference media is obtained from providers. This allows the audience measurement entity to have reference signatures ready when new media is released, eliminating the delay caused by waiting for provider-supplied reference media.
2Productivity
If reference signatures are generated autonomously from captured audio, then timeliness is improved, but the complexity of the system increases
Solution Approach 1:
The system creates candidate reference signatures by copying and processing captured audio segments. Instead of developing complex signature generation algorithms, the system captures audio during playback, processes it through audio encoding to create candidate signatures, and stores them for future matching. This copying approach simplifies the system while maintaining timeliness.
Solution Approach 2:
The system introduces an intermediary process of creating candidate reference signatures from captured audio, which then serves as a bridge between the audio capture phase and the final audience measurement phase. This intermediary candidate signature database allows the system to operate autonomously without directly complex interactions with media providers, simplifying the overall system architecture.
3Reliability
If candidate reference signatures are validated against multiple criteria, then reliability is improved, but the processing time increases
Solution Approach 1:
The system performs validation checks on candidate reference signatures in advance during the signature generation phase, rather than delaying validation until later. By checking criteria such as audio duration thresholds and match counts during the candidate signature creation process, the system ensures only reliable signatures are stored, while maintaining efficient processing through preliminary filtering.

AI summary
Example apparatus disclosed herein are to receive a log file, compare a first media monitor identification associated with an audio signature, a second media monitor identification associated with media metadata, and a third media monitor identification associated with event metadata. Disclosed example apparatus are also to determine if a first timestamp associated with the audio signature is within a time period, wherein the time period begins with a second timestamp associated with the media metadata and ends with a third timestamp associated with the event metadata. Disclosed example apparatus are also to validate that the audio signature satisfies a threshold for being stored as a reference signature based on at least one of the media metadata, the event metadata, the first timestamp, the second timestamp, or the third timestamp. Disclosed example apparatus are also to generate the reference signature including assigning the media metadata to the audio signature.
