Conference Server Analytic Recording for Audio Troubleshooting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional conference recording systems inadequately support troubleshooting of audio and video quality issues during sessions, as they lack detailed data necessary to identify and isolate the root cause of problems such as echoes, poor voice quality, and network-related issues, relying on insufficient recordings and logs.
Innovation Solution
A conference server equipped with an analytic recording module that records mixed audio tracks, original audio tracks of active speakers based on relative loudness, and associated data, along with video tracks, to create an analytic recording container file providing detailed information for troubleshooting, including real-time and dynamic data to help technicians identify and resolve issues.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional conference recording systems record only basic audio-video content, then storage requirements remain manageable, but troubleshooting capability is insufficient due to lack of detailed data
Solution Approach 1:
The patent segments the recording data into multiple organized components: mixed audio track, original audio tracks for each participant, video track, and separate data tracks for participant information, network statistics, and system logs. This segmentation allows comprehensive troubleshooting data to be stored in an organized manner that remains manageable while providing detailed analysis capability.
Solution Approach 2:
The patent introduces an intermediary processing system that captures, organizes, and stores multiple data streams simultaneously. This intermediary recording system acts as a mediator between the conference communication system and the troubleshooting analysis process, capturing detailed data without overwhelming storage resources through efficient data management.
2Measurement precision
If detailed analytic recording data is captured for all participants and system operations, then troubleshooting precision is improved, but system complexity increases
Solution Approach 1:
The recording system is designed with multi-functionality to handle diverse data types (audio, video, network statistics, system logs) through a unified architecture. The same recording infrastructure captures all这些数据 streams simultaneously, avoiding the need for separate complex systems for each data type while maintaining high measurement precision for troubleshooting.
Solution Approach 2:
The patent creates copies of the conference data streams in their original formats without modification, preserving all detailed information exactly as it occurred during the conference. This copying approach maintains measurement precision by avoiding data transformation while the unified recording system manages the complexity of handling multiple data copies.
3Quantity of substance
If only mixed audio track is recorded, then storage requirements are reduced, but ability to isolate specific speaker issues is lost
Solution Approach 1:
The audio recording is segmented into a mixed audio track containing all participants and separate original audio tracks for each individual participant. This segmentation allows storage requirements to remain manageable while enabling easy isolation of specific speaker issues by selecting the appropriate individual track for analysis.
4Productivity
If comprehensive data tracking is implemented for all conference parameters, then analysis capability is enhanced, but processing time increases
Solution Approach 1:
The system performs preliminary action by capturing and organizing all conference data streams during the conference itself, rather than attempting to collect or process data afterward. Network statistics, system logs, and audio-video streams are recorded and structured in real-time, enabling rapid troubleshooting analysis without time-consuming data collection delays.
Data Source
AI summary
A conference server is configured to receive audio signals associated with active speakers at separate conference endpoints, and to mix the audio signals to form a mixed audio signal. The conference server is further configured to record a mixed audio track comprising the mixed audio signal, and to determine a relative loudness of each of the active speakers for given periods of time. The conference server is also configured to record a plurality of original audio tracks that each comprises the original voice of one or more of the active speakers before mixing, wherein the original voice recorded in each of the tracks at the given periods of time is based on the relative loudness of the active speakers.
