Video Conference Record Playback System with Topic Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current video conferencing recording and playback systems lack efficient methods for analyzing and retrieving specific dialogue segments from video conferencing records, making it difficult to navigate and review large recordings effectively.
Innovation Solution
A playback system that includes a streaming analyzing module, topic intensity analyzing module, and dialogue relevance analyzing module to segment and prioritize video conferencing records into manageable chunks based on speech intervals, topic intensity, and relevance, allowing for retrieval and display of specific video clips using keyword indexes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If video conferencing records are recorded in full detail without segmentation, then complete information is preserved, but navigation and review of specific topics become difficult and time-consuming
Solution Approach 1:
The video conferencing record is segmented into multiple streaming chunks based on speech intervals and topic intensity variations. Each chunk represents a discrete segment of the conversation that can be independently analyzed and retrieved, allowing users to quickly navigate to specific topics without reviewing the entire recording.
Solution Approach 2:
The system performs preliminary analysis of the video record during or immediately after recording, pre-segmenting the content into meaningful chunks and indexing them by topic and speaker. This advance preparation enables rapid retrieval of specific segments during playback without requiring real-time processing.
2Ease of operation
If video conferencing records are segmented into many small chunks for easy navigation, then specific topics can be retrieved quickly, but the system complexity increases
Solution Approach 1:
The record is divided into streaming chunks that balance granularity with manageability. The segmentation is performed automatically based on objective criteria (speech intervals, topic intensity) rather than requiring manual intervention, reducing operational complexity while maintaining navigability.
Solution Approach 2:
The system automatically performs the segmentation and indexing operations without requiring user intervention. The streaming analyzing module and topic intensity analyzing module autonomously process the video record to create the segmented structure and keyword indexes, eliminating the need for manual chunking.
3Measurement precision
If topic intensity analysis is performed on all streaming chunks, then accurate dialogue segmentation is achieved, but processing time and computational resources increase
Solution Approach 1:
The analysis process itself is segmented into discrete steps: streaming chunk analysis, topic intensity analysis, and dialogue relevance analysis. Each step processes only the necessary data at that stage, avoiding redundant computations while maintaining segmentation accuracy.
Solution Approach 2:
Topic intensity values are pre-calculated and stored for each streaming chunk during the initial analysis phase. This preliminary computation allows the dialogue relevance analyzing module to quickly compare and evaluate chunks without re-performing the intensive topic intensity calculations during playback or retrieval operations.

AI summary
A playback system for a video conferencing record includes a first electronic device obtaining a video conferencing record and a second electronic device receiving the video conferencing record. The second electronic device analyzes the video conferencing record into a plurality of chunks based on recognizing each dialog in the video conferencing record, analyzing the topic intensity of each dialog, and analyzes the relevance of each chunk to move it out of a dialog or add it to another. Video clips from the video conferencing record can be retrieved according to a keyword index, and the video clips accordingly displayed on a display. A playback method for such video conferencing record or the parts is also provided.
