Multimedia Redirection for Cloud Desktop Conferencing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conferencing software hosted on cloud servers experiences performance issues when presenting multimedia content to multiple remote users, as the host server takes a performance hit and multimedia redirection does not function properly in shared desktop scenarios.
Innovation Solution
A method where a server hosts a remote conference by establishing communication channels with clients, loading multimedia content, splitting it into audio and video streams, and redirecting these streams to clients for local decoding and playback, offloading server demand and reducing network traffic.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the host server presents multimedia content to multiple remote users in a shared desktop scenario, then the conferencing functionality is maintained, but the server experiences performance degradation and multimedia redirection fails
Solution Approach 1:
The patent segments the multimedia processing workload by separating the conferencing server from the multimedia presentation server. The conferencing server handles only control and coordination, while multimedia content is processed and rendered on dedicated presentation servers or local client devices. This segmentation prevents the conferencing server from being overwhelmed by resource-intensive multimedia operations, resolving the contradiction between maintaining multimedia redirection functionality and preserving server performance.
Solution Approach 2:
The patent extracts the multimedia processing function from the conferencing server architecture. Instead of requiring the conferencing server to directly present and manage multimedia content for all participants, the system extracts this function and implements it separately through local client playback or dedicated presentation servers. This extraction eliminates the performance bottleneck while maintaining full multimedia conferencing capability.
2Reliability
If the server processes and sends multimedia content to all clients, then complete multimedia presentation is achieved, but network traffic increases and server load increases
Solution Approach 1:
The patent implements local quality by enabling each client device to independently receive and process only the multimedia content relevant to its user, rather than all clients receiving all content. The system renders multimedia locally at each client device or uses point-to-point streaming, ensuring that each user receives complete multimedia presentation for their experience while minimizing unnecessary network traffic to other participants. This resolves the contradiction between achieving complete multimedia presentation and reducing network energy consumption.

AI summary
In certain information handling system environments, remote conferencing may require the transmission of multi-media content. The server may query a client that has joined the remote conference to determine if the client supports the encoding format of the multi-media content. A source filter may load the requested multi-media content whereupon the multi-media content is split into audio content and video content by a demultiplexor and then transmitted via a multi-media redirection multiplier filter to a proxy client of each client joined to the remote conference or only selected clients. The multi-media content is processed and decoded at the client system using local hardware at the client thereby offloading demand on the server to the client.
