Video Conference Data Stream Indexing via Transcript Linking

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Current video conference systems lack efficient methods for recording and searching through recorded meetings, as manual setup is required for recording and there are no quick ways to access specific parts of the meeting.

Innovation Solution

A method is introduced that initiates a data stream, records it, generates an index by creating a transcript linked to the video portions, and stores it on a data storage device, allowing for easy access and searching of specific meeting parts.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Extent of automation

If manual recording setup is used, then recording can be performed, but the ease of operation deteriorates due to manual configuration requirements

Engineering Contradiction:

Improveautomatic recordingVSAvoidmanual setup

Core Design Contradiction:

Extent of automationVSEase of operation

Solution Approach 1:

The system automatically detects when a video conference is active and initiates recording without requiring manual user intervention. The conference system itself provides the recording service by monitoring and capturing the data stream, eliminating the need for users to manually configure recording equipment or settings.

Inventive Principle:

Principle #25Self-service

2Loss of time

If recorded meetings are stored without indexing, then storage is simple, but the time to access specific parts increases significantly

Engineering Contradiction:

Improvesearch timeVSAvoidindexing system

Core Design Contradiction:

Loss of timeVSDevice complexity

Solution Approach 1:

The system generates an index of the recorded conference data stream during or immediately after recording, before any search operations are performed. This preliminary indexing action creates a searchable structure that enables rapid access to specific conference segments, eliminating the need for users to manually search through entire recorded sessions.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

An index structure serves as an intermediary between the stored conference recording and the user's search queries. Instead of directly searching the entire video data stream, users interact with the index which mediates access by identifying and retrieving only the relevant segments, dramatically reducing access time.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Loss of information

If no transcript is generated, then the system remains simple, but the ability to search and access specific information deteriorates

Engineering Contradiction:

ImprovesearchabilityVSAvoidtranscript generation

Core Design Contradiction:

Loss of informationVSDevice complexity

Solution Approach 1:

The system replaces manual text transcription with automated speech-to-text conversion. A transcript generator automatically converts the audio portion of the conference data stream into text format, enabling users to search through spoken content using text-based queries rather than having to listen to or manually transcribe the audio.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

AI summary

A method of indexing a data stream is disclosed. The method includes initiating the data stream in the video conference, recording the data stream, indexing the data stream by generating a transcript of the recorded data stream, linking the transcript with a video portion of the data stream and storing the indexed data stream onto a data storage medium.
