Solution Overview

Problem

Current systems lack an efficient method to identify in real-time the primary media stream position causing a series of language communications on a secondary channel, especially when the topic shifts from the original content, making it difficult to track and rewind to the relevant point in the primary media stream.

Innovation Solution

A topic transition analysis system that includes a statement trigger string determination unit to determine whether a statement on a language stream has been made in response to the media stream contents, using topic similarity calculations to identify the point on the primary media stream that led to the series of statements, suitable for real-time processing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If users focus on language communication in the secondary stream, then communication efficiency is improved, but users may fail to track the primary media stream and miss important content

Engineering Contradiction:
Improvecommunication efficiencyVSAvoidmissed media stream content
Core Design Contradiction:
ProductivityVSLoss of information

Solution Approach 1:

The system provides feedback by analyzing language stream content and identifying the corresponding position in the media stream that triggered the discussion. This feedback mechanism allows users to understand what media content they might have missed while engaging in secondary stream communication, resolving the contradiction between communication efficiency and information tracking.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The topic transition analysis system acts as an intermediary between the media stream and language stream. It analyzes the language stream content, determines the triggering media stream position, and provides this information to users, enabling them to track both streams effectively without missing important content.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If the topic in language communication shifts from the original media stream content, then discussion depth is improved, but it becomes difficult to identify the original triggering point in the media stream

Engineering Contradiction:
Improvediscussion depthVSAvoidtopic position identification accuracy
Core Design Contradiction:
Adaptability or versatilityVSMeasurement precision

Solution Approach 1:

The system performs preliminary analysis of the language stream to detect topic transitions before they significantly diverge from the original media content. By identifying topic shifts early and tracking them back to the original triggering point, the system maintains accurate position identification even as discussions evolve and deepen.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system analyzes not only the current language stream content but also the historical context and topic evolution. By examining partial sequences of language content leading up to the current statement, it can accurately trace back to the original media stream position that initiated the discussion, even when topics have shifted.

Inventive Principle:
Principle #16Partial or excessive action

3Ease of operation

If real-time analysis of language streams is performed to identify media stream positions, then user ability to catch up on missed content is improved, but processing complexity increases

Engineering Contradiction:
Improveease of catching up on missed contentVSAvoidprocessing complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The system extracts only the essential information needed for position identification from the language stream, rather than performing comprehensive analysis of all content. By focusing on key indicators such as topic keywords and transition points, it reduces processing complexity while maintaining the ability to accurately identify media stream positions for user reference.

Inventive Principle:
Principle #2Taking out (Extraction)

AI summary

The present invention provides a topic transition analysis system that determines a position on a primary media stream leading to a certain statement made in a language communication carried out in a secondary channel associated with the primary media stream. The topic transition analysis system includes a statement trigger string determination unit receiving a primary media stream and one or a plurality of language communication streams (hereinafter, language streams) executed in parallel with the media stream and determining whether or not a certain statement on the one or plurality of language streams has been made newly in response to contents of the media stream.
