Mismatched Query Fingerprints for Accurate Media Identification

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing media identification systems using fingerprint matching can incorrectly identify media content due to samples or promos, leading to delayed and incorrect metadata presentation, and the validation process to correct this can further delay the presentation.

Innovation Solution

Utilize the most recently mismatched query fingerprint as a basis for validation, allowing immediate comparison with reference fingerprints to confirm the new media identification before presenting metadata, thereby reducing delays and improving accuracy.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the system waits for a validation process to confirm new media identification before presenting metadata, then accuracy is improved, but presentation time is delayed

Engineering Contradiction:

Improveidentification accuracyVSAvoidmetadata presentation delay

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The system performs preliminary fingerprint matching and stores mismatched query fingerprints before validation is complete. When a new identification is made, the system can immediately validate using pre-stored fingerprints rather than waiting for them to be generated, thus reducing validation time while maintaining accuracy

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system prepares validation data in advance by storing mismatched query fingerprints and their timestamps. This cushioning of preparatory work ensures that when validation is needed, the system can immediately proceed without delay, balancing the need for accurate validation with timely metadata presentation

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)

2Adaptability or versatility

If the system uses fingerprint matching to identify media content, then identification capability is improved, but incorrect identification occurs due to samples or promos

Engineering Contradiction:

Improvemedia identification capabilityVSAvoididentification accuracy

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The system continuously monitors fingerprint matching results and uses feedback from mismatched fingerprints to trigger re-evaluation. When a mismatch is detected, the system validates the identification by comparing against additional reference fingerprints or adjusting matching thresholds, thereby correcting errors caused by samples or promos while maintaining the ability to identify diverse media content

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The system takes preliminary anti-action by validating identifications that show mismatched fingerprints before presenting metadata. This prevents incorrect identifications from samples or promos by proactively checking for consistency across multiple fingerprint comparisons, thereby counteracting the tendency toward false positives

Inventive Principle:

Principle #9Preliminary anti-action

3Reliability

If the system performs validation process to correct incorrect identification, then accuracy is improved, but presentation time is further delayed

Engineering Contradiction:

Improveidentification accuracyVSAvoidvalidation delay

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The system performs preliminary preparation by storing mismatched query fingerprints and their contextual information before validation is required. This advance preparation allows the validation process to proceed immediately when triggered, reducing the time penalty of validation while maintaining its accuracy-improving function

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system dynamically adjusts validation parameters based on the situation. When a mismatch is detected, the system changes the validation threshold or selects specific reference fingerprints for comparison, optimizing the validation process to be both accurate and efficient, thereby reducing validation delay while maintaining accuracy

Inventive Principle:

Principle #35Parameter changes

AI summary

A method for controlling presentation of metadata regarding media. A system could generate query fingerprints representing media content being presented, the media content having been identified as being a first media-content item. The system could further detect a threshold mismatch comprising at least one of the query fingerprints not matching any of first reference fingerprints known to represent the first media-content item. In response, the system could engage in new media identification, establishing that the media content is a second media-content item, and could obtain both second reference fingerprints known to represent the second media-content item and metadata regarding the second media-content item. Further, the system could validate the new identification as a condition precedent to presenting the obtained metadata, the validating including comparing with the obtained second digital reference fingerprints the at least one digital query fingerprint that did not match any of the first digital reference fingerprints.
