AoIP Audio Center Network for Long-Distance Sound Quality Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing audio systems face challenges in efficiently transmitting audio signals across remote locations, leading to sound quality degradation and increased costs due to the need for costly analog-to-digital and digital-to-analog converters, as well as limitations in network-based audio transmission technologies like CobraNet and Dante, which do not effectively manage audio environments or perform level control.
Innovation Solution
An on-site audio center system based on Audio over Internet Protocol (AoIP) that connects multiple audio input devices to output devices through audio transmitting and receiving modules, with a hub module and control personal computer to configure and manage the AoIP network, allowing for point-to-point, one-to-many, many-to-one, or many-to-many audio transmission schemes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If audio signals are transmitted through remote locations using traditional audio systems, then audio transmission is achieved, but sound quality degrades due to line loss
Solution Approach 1:
The patent replaces traditional mechanical audio transmission systems with AoIP-based digital network transmission. By converting audio signals to digital IP packets and transmitting them through Ethernet networks, the system eliminates analog line loss and electromagnetic interference, maintaining sound quality over remote distances without requiring costly ADC/DAC converters at each endpoint.
Solution Approach 2:
The patent changes the transmission parameter from analog electrical signals to digital IP packets. This parameter transformation enables audio signals to be transmitted over standard IP networks with inherent error correction and regeneration capabilities, preventing sound quality degradation over distance.
2Reliability
If costly ADC and DAC converters are used for audio transmission, then audio signal conversion is achieved, but system cost increases
Solution Approach 1:
The patent makes the network infrastructure universal by using standard IP networks for audio transmission. The same Ethernet cables and network switches used for data communication are also used for audio transmission, eliminating the need for separate audio transmission infrastructure and costly dedicated converters at each endpoint.
Solution Approach 2:
The patent enables the network infrastructure to serve dual purposes - both data communication and audio transmission. The IP network automatically handles audio packet routing, timing synchronization, and error correction without requiring additional specialized hardware or converters.
3Productivity
If CobraNet or Dante technologies are used for audio transmission, then network-based audio transmission is achieved, but audio environment management and level control are limited
Solution Approach 1:
The patent introduces an audio center server as an intermediary that centralizes audio environment management. The server handles audio routing, level control, and system configuration, providing a user-friendly interface that simplifies operation while maintaining efficient AoIP-based audio transmission between devices.
