Multimedia Conference Broadcast System Server Architecture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multimedia conference systems face challenges in broadcasting composite multimedia streams to third-party viewers, as participants' devices often lack the necessary processing resources and content distribution capabilities, and existing television systems are inefficient and unsuitable for combining multiple video streams from participants, especially when scalability and resource availability are concerns.
Innovation Solution
A multimedia conference broadcast system that employs a server to receive and combine audio and video streams from participant devices, generate a composite stream, and broadcast it to viewer devices over the Internet, using scalable video codecs and adaptive layout modifications to optimize quality and bandwidth, while allowing controlling participants to manage stream characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If participant devices generate and broadcast composite multimedia streams directly, then broadcasting capability is achieved, but device processing resources and content distribution capabilities are insufficient
Solution Approach 1:
The patent introduces a server as an intermediary component that receives individual video streams from multiple participant devices, combines them into a composite multimedia stream, and distributes it to viewer devices. This mediator approach transfers the complex processing burden from resource-constrained participant devices to a powerful centralized server, enabling broadcasting functionality without requiring participants to have sufficient processing resources or content distribution capabilities
Solution Approach 2:
The system segments the broadcasting function into separate components: participant devices only need to capture and transmit individual video streams, while the server handles the complex tasks of stream combination, composite stream generation, and distribution to multiple viewers. This segmentation allows participant devices to remain simple while achieving sophisticated broadcasting capabilities through server-side processing
2Productivity
If television systems are used to combine multiple video streams, then composite stream generation is achieved, but efficiency and suitability for Internet broadcasting are poor
Solution Approach 1:
The patent replaces traditional television system mechanisms with Internet-based digital processing. Instead of using television production equipment and broadcast infrastructure, the system uses software-based video stream processing on a server connected to the Internet, enabling efficient combination of multiple video streams and direct distribution to viewer devices over Internet protocols, which is both more efficient and better suited for Internet broadcasting than traditional television systems
3Loss of information
If multiple video streams are combined in real-time, then composite multimedia stream is generated, but bandwidth consumption and processing load increase
Solution Approach 1:
The server merges multiple individual video streams into a single composite multimedia stream that contains all participant video feeds. By consolidating the streams into one composite stream for distribution to viewers, the system efficiently utilizes bandwidth while maintaining all video content, rather than sending separate streams to each viewer device
Data Source
AI summary
A multimedia conference broadcast system may include one or more processors and a memory. The one or more processors may receive video streams and audio streams from participant devices. The one or more processors may transmit, to each of the participant devices, the video streams and the audio streams corresponding to the other devices. The one or more processors may receive a request to broadcast the video streams and the audio streams from one of the participant devices. The one or more processors may generate a composite multimedia stream based on the video streams and the audio streams received from the participant devices. The one or more processors may broadcast the composite multimedia stream to viewer devices that are separate from the participant devices.
