Media Server Grouping and Merging Video Streams
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
As the number of client devices participating in a video conference increases, the amount of data transmitted for media streams also increases, leading to excessive network traffic and resource utilization. Additionally, high-quality video stream configurations further exacerbate this issue.
Innovation Solution
An electronic device and method that enable a media server to classify client devices into groups and receive a merged video stream from a master device within each group, thereby reducing network traffic. The image quality of the video stream is configured based on the bandwidth between the master device and the media server.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the number of client devices participating in a video conference increases, then the conference functionality is improved, but the network traffic and resource utilization increase excessively
Solution Approach 1:
Multiple video streams from slave devices are merged into a single video stream by the master device. The master device receives video streams from slave devices, performs merging processing, and transmits the merged stream to the server, thereby reducing the total number of transmitted streams while maintaining all participant videos in the conference
Solution Approach 2:
Client devices are segmented into master devices and slave devices based on network conditions and device capabilities. This segmentation allows different devices to perform different functions: slave devices capture and transmit local videos, while the master device performs merging and single-stream transmission to the server
2Manufacturing precision
If the image quality of the video stream is configured high, then the video quality is improved, but the network traffic increases rapidly
Solution Approach 1:
The system dynamically adjusts video stream parameters (resolution, frame rate, bitrate) based on network conditions. The server or master device monitors network bandwidth and modifies the video stream quality parameters accordingly, allowing high quality when bandwidth is充足 and automatic degradation when bandwidth is limited
Solution Approach 2:
The video stream quality is made dynamic rather than static. The system continuously adapts the image quality configuration based on real-time network conditions, transitioning between different quality levels to maintain optimal balance between video quality and network traffic consumption
