Video Teleconferencing Participant Status Indicators
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional video teleconferencing services lack real-time participant status indicators, leading to unawareness of network and system instabilities, which can cause misunderstandings and interruptions during discussions.
Innovation Solution
The method involves generating video histograms and audio signatures for each participant, determining their connectivity status in real-time, and displaying indicators through a graphical user interface, with the option to take corrective actions such as terminating video connections or pausing audio when necessary.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If conventional video teleconferencing services are used without status indicators, then the system remains simple and easy to operate, but participant status and connectivity issues remain undetected causing misunderstandings and interruptions
Solution Approach 1:
The patent introduces video histograms and audio signatures as intermediary elements that mediate between the complex video/audio processing and the simple status indicator display. These intermediaries transform raw video and audio data into compact representations that can be easily compared and evaluated to determine participant status without requiring complex real-time analysis of the actual video and audio streams
Solution Approach 2:
The patent creates simplified copies of the actual video and audio content through histograms and audio signatures. Instead of analyzing the full video and audio data, the system uses these compact representations that capture essential characteristics, allowing status determination with minimal computational overhead while maintaining accuracy
2Reliability
If real-time status monitoring is implemented using video histograms and audio signatures, then participant status becomes transparent and connectivity issues can be detected, but the computational processing and system complexity increase
Solution Approach 1:
The patent performs preliminary processing by generating video histograms and audio signatures from video and audio data. These pre-processed representations are created in advance of the actual status determination step, transforming complex data into compact forms that can be quickly compared against expected values to detect connectivity issues
Solution Approach 2:
The patent transforms video and audio data into different parameter spaces through histograms and audio signatures. By changing the representation parameters from raw pixel values and audio waveforms to histogram distributions and spectral features, the system enables efficient comparison and status detection with reduced computational complexity
3Measurement precision
If video histograms and audio signatures are generated and compared in real-time, then accurate status determination is achieved, but the processing time and computational resources increase
Solution Approach 1:
The patent extracts only the essential characteristics of video and audio data through histograms and audio signatures. By taking out and isolating the key features (color distribution in video, spectral content in audio) rather than processing the complete data streams, the system achieves accurate status determination with minimal processing time
Solution Approach 2:
The patent applies partial action by generating status indicators for only the most critical aspects of participant state (connectivity status, active/inactive state) rather than analyzing all possible video and audio parameters. This selective approach maintains high measurement precision for the most important metrics while keeping processing time low

AI summary
A method for providing participant status to facilitate video teleconferencing management is disclosed. The method includes receiving a starting indication that a video teleconference has been initiated, the video teleconference including a plurality of participants; generating a video histogram for each of the plurality of participants, the video histogram corresponding to an image that is captured for each of the plurality of participants; capturing an audio signature for each of the plurality of participants; determining, in real-time, a status for each of the plurality of participants based on the corresponding video histogram and the corresponding audio signature, the status relating to a connectivity status for the video teleconference; generating an indicator for each of the plurality of participants based on the corresponding status; and displaying, via a graphical user interface, the indicator for the plurality of participants, the graphical user interface corresponding to the initiated video teleconference.
