Solution Overview

Problem

Current copyright protection schemes for live media streams are inefficient in detecting violations in real-time, leading to delays and incomplete identification of unauthorized content, as they often require extensive processing and may miss previously uploaded content when the matching system is offline.

Innovation Solution

A system that monitors live media streams by constructing fingerprints and patterns, using a violation index to rapidly identify potential violations, allowing for efficient comparison and modification of the media content presentation, such as termination or interruption, based on predefined policies.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If conventional copyright protection schemes compare uploaded media content to an index of validated content, then copyright claims can be generated against matching content, but processing delays and system offline periods cause previously uploaded content to be missed

Engineering Contradiction:
Improvedetection accuracyVSAvoidprocessing delay
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The system performs preliminary actions by constructing fingerprints and patterns from live media streams in real-time before the matching system is fully online. This allows the violation index to be pre-populated with reference data from the live stream, so that when content upload occurs, the comparison can happen immediately without delay. The fingerprint construction happens concurrently with stream processing, ensuring reference material is ready ahead of time.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent introduces an intermediary mechanism - the violation index - that acts as a buffer between the live stream processing and the copyright matching system. The violation index stores fingerprints and patterns from the live stream, allowing the matching system to compare uploaded content against this intermediate storage even when the main matching system is offline or experiencing delays. This intermediary layer ensures continuous detection capability.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Productivity

If the matching system processes live streams in real-time, then copyright violations can be detected, but extensive processing time is required which causes interruptions between broadcast and reference upload

Engineering Contradiction:
Improvedetection speedVSAvoidprocessing complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The system segments the copyright protection process into distinct components: fingerprint construction from live streams, pattern generation, violation index population, and content matching. By dividing the complex processing task into these manageable segments that can operate independently and in parallel, the system achieves real-time detection capability without being overwhelmed by processing complexity. Each segment handles a specific aspect of the detection workflow.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent changes key parameters of the processing system by implementing asynchronous operations and background processing for fingerprint construction and violation index updates. This allows the matching operation to run with optimized real-time parameters while the heavier processing tasks occur in the background, effectively decoupling the speed requirements of different processing stages and enabling fast detection without excessive overall system complexity.

Inventive Principle:
Principle #35Parameter changes

3Speed

If user uploaded content is processed before the live stream is indexed, then content can be uploaded quickly, but the matching system cannot claim previously uploaded content

Engineering Contradiction:
Improveupload speedVSAvoiddetection reliability
Core Design Contradiction:
SpeedVSReliability

Solution Approach 1:

The system performs preliminary indexing of the live stream into the violation index before user content upload occurs. By pre-processing the live stream and storing its fingerprints in the violation index, the system ensures that when user content is uploaded, the reference material is already available for immediate comparison. This preliminary action eliminates the timing conflict between upload speed and detection reliability.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent implements continuous operation of the fingerprint construction and violation index population processes, ensuring that the detection capability is always active and up-to-date. The system maintains continuous indexing of the live stream and continuous availability of the violation index, so that content upload and detection can occur simultaneously without interruption or loss of reliability. This continuous action ensures no content is missed regardless of upload timing.

Inventive Principle:
Principle #20Continuity of useful action

AI summary

Systems and methods modifying a presentation of media content in response to a detected violation are provided. In particular, media content such as a media stream broadcasted by a user to other users can be monitored. The broadcasted media stream can be fingerprinted and compared to a fingerprint repository that includes entries associated with media content that is copyrighted or otherwise considered a violation. If the fingerprint matches entries included in the fingerprint repository, then the media stream can be modified such as modified to terminate.
