Queued Content Sharing for Seamless Online Conference Transitions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In online conferencing, switching between presenters often results in delays of 10-30 seconds due to the conference server acquiring and distributing new content, disrupting the flow of the meeting.
Innovation Solution
Implementing a pre-sharing mechanism where content from the next presenter is queued and made available at the participants' devices before the switch, allowing for immediate display when the presenter transitions, reducing the delay to less than one second.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If content is shared through the conference server in real-time, then content authenticity is maintained, but transition delay increases to 10-30 seconds
Solution Approach 1:
The system pre-loads content from the next presenter into a local queue at each participant's device before the presenter transition occurs. This preliminary action allows the content to be ready locally, eliminating the 10-30 second delay while maintaining content authenticity through subsequent verification against the conference server.
Solution Approach 2:
A local queue mechanism acts as an intermediary between the conference server and the display system. This queue stores pre-loaded content locally, allowing immediate display during presenter transitions while the system maintains content authenticity by verifying the queued content against the conference server's authoritative source.
2Speed
If content is pre-loaded at participant devices, then transition speed increases to less than one second, but network bandwidth consumption increases
Solution Approach 1:
The system implements differentiated content handling: frequently accessed or upcoming presenter content is pre-loaded locally at each participant's device, while other content remains on the server. This local quality approach optimizes transition speed for critical content while minimizing overall network bandwidth consumption by not pre-loading all content universally.
Solution Approach 2:
Instead of pre-loading all possible content, the system selectively pre-loads only the content from the next presenter that is most likely to be needed during transitions. This partial action approach achieves sufficient transition speed improvement without the excessive network bandwidth consumption of universal pre-loading.
3Stability of the object's composition
If content is queued locally at each device, then transition smoothness is improved, but device storage requirements increase
Solution Approach 1:
The system pre-loads only the essential first frame or initial content of the next presenter into the local queue, rather than storing complete presentations. This preliminary action provides sufficient content for smooth transition initiation while minimizing device storage requirements.
Solution Approach 2:
The system extracts only the critical initial content (first frame or key elements) from the next presenter's full content and stores it locally in the queue. The remaining content remains on the server and is loaded on-demand, achieving transition smoothness without requiring substantial device storage capacity.
Data Source
AI summary
In one embodiment, a method includes sharing first content from a first computer of a first participant in an online conference. The first content is shared on a second display of a second computer of a second participant in the online conference. During the sharing of the first content, third content from a third computer of a third participant is queued in a queue at the second computer without display on the second display. For a transition from the first participant to the third participant in the online conference, the third content is shared on the second display of the second computer from the queue.
