Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional systems face challenges in detecting unauthorized content, such as copyrighted material, in live, multi-user composite media streams, especially in real-time, due to the complexity of composite streams and the difficulty in distinguishing between fair use, accidental inclusion, and false positives, leading to potential false shutdowns and user dissatisfaction.

Innovation Solution

A system comprising a receiving component to gather multi-user composite media streams, a partition component to identify portions associated with individual users, a detection component to identify unauthorized content, and a notice component to notify the responsible user, allowing for real-time detection and mitigation of unauthorized content while minimizing false positives through aggressive notification thresholds and targeted enforcement.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional systems monitor multiuser composite media streams for unauthorized content, then copyright protection is improved, but false positives increase leading to false shutdowns

Engineering Contradiction:

Improvecopyright protectionVSAvoiddetection accuracy

Core Design Contradiction:

ReliabilityVSMeasurement precision

Solution Approach 1:

The system segments the multiuser composite media stream into individual user streams using a partition component before detection. This allows the detection component to analyze each user's content separately, identifying the specific user responsible for unauthorized content while reducing false positives caused by mixing multiple users' streams.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent introduces an intermediary notification system that alerts users about potential copyright violations before taking enforcement action. This intermediary step allows users to rectify accidental violations, reducing false shutdowns while maintaining copyright protection.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Difficulty of detecting and measuring

If aggressive detection thresholds are used to identify unauthorized content, then detection sensitivity is improved, but false positives increase

Engineering Contradiction:

Improvedetection sensitivityVSAvoidfalse positive rate

Core Design Contradiction:

Difficulty of detecting and measuringVSReliability

Solution Approach 1:

The system implements feedback through notifications sent to users when unauthorized content is detected. Users can respond to these notifications to confirm or refute the detection, providing feedback that helps adjust detection thresholds and reduce false positives while maintaining high sensitivity.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

Instead of immediately shutting down streams upon detection, the system applies partial action by sending notifications first. This allows for verification and user response before taking excessive enforcement action, reducing false positives while maintaining detection sensitivity.

Inventive Principle:

Principle #16Partial or excessive action

3Loss of time

If real-time detection is implemented in multiuser composite streams, then response time is improved, but system complexity increases

Engineering Contradiction:

Improveresponse timeVSAvoidsystem complexity

Core Design Contradiction:

Loss of timeVSDevice complexity

Solution Approach 1:

The system reduces complexity by segmenting the composite stream into individual user streams before real-time detection. This segmentation allows parallel processing of simpler individual streams rather than analyzing the complex composite stream as a whole, achieving real-time detection with reduced system complexity.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The partition component performs preliminary action by organizing and separating user streams before detection occurs. This preliminary organization simplifies the subsequent real-time detection process, reducing computational complexity while maintaining fast response times.

Inventive Principle:

Principle #10Preliminary action

4Adaptability or versatility

If service providers monitor all user content, then content control is improved, but user freedom deteriorates

Engineering Contradiction:

Improvecontent controlVSAvoiduser freedom

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The notification system acts as an intermediary between content control and user freedom. It provides service providers with content control capability while giving users the freedom to respond and rectify accidental violations, balancing both interests through a collaborative enforcement approach.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

Systems and methods described herein relate to detecting the existence of unauthorized content in multiuser composite media stream. In particular, multiuser composite media streams can be examined and to determine if these composite streams include unauthorized content such as copyrighted content or nudity, violence, language violations where desired. The multiuser composite media stream can be partitioned into sections associated with broadcasting users and the portions can be analyzed independently. A notification can be provided to, e.g., the broadcasting user responsible for the unauthorized content in response to detection of the unauthorized content.
