Multimedia Stream Consolidation for Remote Conference Audio Video
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In collaborative workspaces, remote participants often face difficulties in clearly viewing or hearing specific participants in a conference room due to multiple participants speaking simultaneously and movement within the room, leading to suboptimal audio and video feeds.
Innovation Solution
A system that allows remote participants to receive individually customized audio and video feeds by selecting from multiple camera and microphone sources, with the computing device managing and consolidating feeds to optimize the experience, enabling remote control of camera and microphone settings to track and focus on specific participants.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple camera and microphone sources are provided to capture different participants in the conference room, then the ability to view and hear specific participants is improved, but the device complexity and bandwidth requirements increase
Solution Approach 1:
The system divides the conference room environment into multiple independent camera and microphone sources, each capturing specific participants or zones. This segmentation allows remote participants to select and receive only the relevant feeds they need, improving adaptability while managing complexity through modular organization of multiple independent capture devices.
Solution Approach 2:
Different cameras and microphones are positioned to capture specific local areas or participants within the conference room. Each feed has optimized quality for its specific target (e.g., a camera focused on a speaker, microphones near specific participants), allowing remote users to receive customized high-quality feeds for the participants they wish to follow, rather than a single generic feed.
2Adaptability or versatility
If individually customized audio and video feeds are provided to each remote participant, then the interaction quality is improved, but the bandwidth requirements and data transmission load increase
Solution Approach 1:
Instead of transmitting all available camera and microphone feeds to all remote participants, the system provides only the subset of feeds that each participant has selected and needs. This partial action approach maintains high customization quality for each user while significantly reducing the total bandwidth consumption compared to transmitting all feeds to everyone.
Solution Approach 2:
The system dynamically changes transmission parameters based on user selections and current meeting conditions. Feed customization allows the system to adjust which streams are transmitted, at what quality levels, and to which recipients, optimizing the balance between interaction quality and bandwidth utilization by transmitting only necessary data at appropriate resolutions.
3Ease of operation
If remote participants can control camera and microphone settings to track specific participants, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The system introduces a control intermediary layer that manages the complexity of camera and microphone control on behalf of remote participants. This intermediary handles the coordination of selecting and switching between multiple feeds, managing the complexity of controlling multiple devices while providing a simplified interface to remote users who can easily select which participants they want to follow without dealing with the underlying system complexity.
Solution Approach 2:
The system implements feedback mechanisms that automatically adjust camera and microphone selections based on meeting dynamics. When a participant becomes the active speaker or moves to a different zone, the system receives feedback about the current meeting state and can automatically switch feeds or notify remote participants of available changes, reducing the operational burden on remote users while maintaining ease of use.

AI summary
Examples disclosed herein provide the ability for remote participants in a collaborative workspace to hear and view specified participants in a conference room. In on example, a computing device may receive streams of content from devices located in a room, and receive requests from users. As an example, each user request is for accessing a subset of the streams of content. For each user request, the computing device may join the requested subset of the streams of content into a single multimedia stream, and transmit each single multimedia stream to respective users.
