Video Conference System Peer-to-Peer Server Elimination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current video conferencing using 3G cellular networks is limited by coverage area and high communication costs, and requires a server to organize and transmit data, causing inconvenience in multi-way conferences.
Innovation Solution
A video conference system that includes an audio processing unit, a video processing unit, and a network processing unit to encode and transmit audio and video streams across multiple terminals in a network, allowing for multi-way conferences without the need for an additional processor, using a multimedia capturing unit, DECT telephone, and network processing unit to convert signals into network packets for transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a server is used to organize and transmit data for multi-way conferences, then the video conferencing can be conducted across multiple terminals, but the system complexity increases and requires additional dedicated infrastructure
Solution Approach 1:
Each terminal in the video conferencing system performs self-service by encoding and transmitting its own audio and video streams directly to other terminals through the network. The terminals also decode and process received streams locally, eliminating the need for a central server to organize and transmit data. This peer-to-peer approach maintains multi-way conference capability while reducing system complexity and infrastructure requirements.
2Measurement precision
If video signals are transmitted with high resolution, then the video quality is improved, but the bandwidth consumption increases
Solution Approach 1:
The system dynamically adjusts video transmission parameters by encoding video signals at appropriate resolutions based on terminal capabilities and network conditions. The audio processing unit and video processing unit convert audio and video signals to streams with optimized parameters, balancing video quality and bandwidth consumption. This allows high-resolution transmission when necessary while reducing bandwidth usage during normal operations.

AI summary
A video conference method, applied to a video conference system in a multi-way conference is provided. The video conference method includes: retrieving a first number of a plurality of terminals of the multi-way conference; determining whether at least one other terminal is requiring to join in on the multi-way conference; when the at least one other terminal is requiring to join in on the multi-way conference, increasing the first number of the terminals of the multi-way conference to a second number of the terminals; and determining a resolution of the video signal captured and transmitted by the video conference system according to the second number of the terminals. A video conference system using the video conference method, is also provided.
