Distributed Conferencing via Multicast Data Streams
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current conferencing systems for remote participants often suffer from lower quality experiences due to server disruptions, poor audio quality, and confusion regarding content origination, as they rely on centralized servers for distributing meeting contents.
Innovation Solution
Distributed conferencing systems that use multiple authorized source units to generate and transmit separately-decodable real-time data streams to a common multicast IP address, eliminating the need for centralized servers and allowing for flexible management of meeting content without interruptions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a centralized server is used to distribute meeting contents, then all content can be managed from a single point, but any server disruption affects all content provided
Solution Approach 1:
The patent segments the centralized content delivery system into multiple independent source units, each responsible for specific content streams (audio, video, data). This segmentation allows individual units to fail without affecting the entire system, resolving the contradiction between centralized management ease and system reliability.
2Adaptability or versatility
If multiple content streams are managed by different servers, then content specialization is improved, but coordination complexity increases
Solution Approach 1:
The patent merges multiple independent content streams from different source units into a single unified multicast group address. This combining approach allows specialized content management at the source level while simplifying coordination at the network level through unified multicast routing, resolving the contradiction between content specialization and coordination complexity.
3Loss of energy
If multicast distribution is used for efficient one-to-many communication, then network infrastructure usage is optimized, but content origination becomes confusing with multiple senders
Solution Approach 1:
The patent applies local quality by assigning unique identifiers and source-specific parameters to each content stream within the multicast distribution. This allows the network to efficiently route multicast packets while maintaining clear identification of each content's origin through source-specific metadata and addressing, resolving the contradiction between network efficiency and origin clarity.
Data Source
AI summary
Distributed conferencing systems and methods provide local meeting contents to remote participants. In accordance with various example embodiments, a plurality of authorized source units generate media content responsive to and representative of respective content for a meeting. In response to the generated media content, one or more data streams are developed at each authorized source, each stream being a separately-decodable real-time representation of at least a portion of the media content generated at the respective authorized source. The separate data streams are transmitted by each authorized source to a common multicast IP group address for retrieval/access by remote participants.
