VoIP Audio Bridge Segments Computer and Voice Streams
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
During web conferencing, the separation of computer audio and presenter/viewer audio streams is challenging, leading to audio quality deterioration due to leakage and interference when separate speakers and microphones are used, rather than integrated headsets.
Innovation Solution
The implementation of a system with voice and computer audio engines, along with a voice conference bridge, that cancels echo and feedback between audio streams, ensuring clean transmission of both computer and presenter/viewer audio streams without mixing, using VoIP technology and sound processing components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate speakers and microphones are used instead of integrated headsets, then multiple participants can listen and speak at the same location, but computer audio leaks from the speaker to the microphone causing audio quality deterioration
Solution Approach 1:
The system segments audio processing into distinct components: a voice conference bridge handles voice audio streams while a computer audio bridge handles computer audio streams. This segmentation allows separate processing paths that prevent leakage and interference between different audio sources, resolving the contradiction by maintaining audio quality while supporting multiple participants.
Solution Approach 2:
The patent introduces intermediary components including a voice conference bridge and computer audio bridge that act as mediators between different audio sources and the mixing device. These intermediaries process and manage audio streams separately before combination, preventing direct leakage from speakers to microphones while enabling multiple participants to communicate effectively.
2Productivity
If computer audio is transmitted separately from presenter/viewer audio, then both audio streams can be received by the conference, but interference and mixing occur degrading audio quality
Solution Approach 1:
The system divides audio transmission into separate segmented channels: a voice conference bridge for voice audio streams and a computer audio bridge for computer audio streams. Each bridge processes its designated audio type independently, then transmits to the mixing device without interference or mixing, maintaining audio quality while enabling simultaneous transmission of multiple audio streams.
Solution Approach 2:
The patent employs intermediary bridges that act as dedicated mediators for different audio types. The voice conference bridge mediates voice audio streams while the computer audio bridge mediates computer audio streams, ensuring separate processing and transmission paths that prevent interference and mixing, thus preserving audio quality during simultaneous transmission.

AI summary
A new approach is proposed that contemplates systems and methods to support canceling audio streams leaked from a speaker to a microphone so that a clean audio stream of a presenter or viewer speaking at a conference call is transmitted. Here, the audio streams being canceled includes the computer audio stream of an application being run or a material being presented online during a web conference and/or the audio stream received from the rest of the group of participants at the conference call. The computer audio stream is then transmitted in addition to the presenter or viewer audio stream, and separate from any other audio stream captured by the hosting device during the conference call.
