Active Network Manager for Live Audio Latency Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Streaming live audio over wireless networks faces challenges such as latency, jitter, packet loss, and excessive noise, which can degrade audio quality and make it difficult for speakers to communicate effectively in real-time scenarios.
Innovation Solution
A system utilizing a wireless network hub and an Active Network Manager (ANM) to manage communications between personal mobile devices and a public address system. The ANM monitors dynamic network parameters, qualifies client devices, and adjusts network settings to maintain voice stream quality according to configurable rules.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If audio is broadcast over a public address system in the presence of the speaker, then real-time audio feedback is achieved, but excessive noise and latency make it difficult for the speaker to speak normally
Solution Approach 1:
The system performs preliminary actions by pre-qualifying client devices and establishing network parameters before audio streaming begins. The Active Network Manager pre-assesses device capabilities, network conditions, and potential interference sources, configuring optimal settings in advance to minimize latency and noise before the speaker begins speaking.
Solution Approach 2:
The Active Network Manager acts as an intermediary between the audio capture devices, network infrastructure, and public address system. It mediates network traffic, manages device qualifications, and coordinates communication to reduce latency and eliminate excessive noise, allowing the speaker to communicate comfortably without direct exposure to their own broadcast audio.
2Adaptability or versatility
If network traffic is increased to support multiple devices, then system versatility is improved, but audio quality deteriorates due to packet loss and jitter
Solution Approach 1:
The system applies local quality by implementing device-specific qualification and network parameter optimization for each client device. The Active Network Manager assesses individual device capabilities, network conditions, and audio quality requirements, configuring tailored settings for each device to ensure high-quality audio streaming while supporting multiple diverse devices simultaneously.
Solution Approach 2:
The system implements dynamic management by continuously monitoring network conditions, device performance, and audio quality metrics. The Active Network Manager dynamically adjusts network parameters, requalifies devices as needed, and adapts streaming settings in real-time to maintain audio quality while supporting multiple devices with varying capabilities and network conditions.
3Ease of operation
If live audio streaming is enabled for all devices, then system accessibility is improved, but audio quality suffers from noise and latency
Solution Approach 1:
The system performs preliminary device qualification and network assessment before enabling live audio streaming. The Active Network Manager pre-evaluates device capabilities, network bandwidth, and potential interference sources, configuring optimal settings in advance to ensure high-quality audio streaming while maintaining broad device accessibility.
Solution Approach 2:
The system implements continuous feedback mechanisms by monitoring audio quality metrics, network performance, and device status in real-time. The Active Network Manager uses this feedback to dynamically adjust streaming parameters, requalify devices, and optimize network resources, ensuring high-quality audio while maintaining accessibility for multiple devices.
Data Source
AI summary
Active management of a data network facilitates the high-quality live broadcast of captured digital audio from multiple client devices present in a venue. In various aspects, the system includes a network hub. The network hub transmits and receives data from a plurality of the client devices which may be personal mobile devices. A network manager component manages communications of the client devices with the network hub. The network manager uses measured dynamic network parameters and determines conditions for maintaining audio quality according to configurable rules. The dynamic network parameters may include device qualification(s), live measured audio quality of service metrics, and unwanted data packets. In various aspects, dynamic authentication and de-authentication of client devices as well as data transmission throttling of client devices are techniques utilized for active network management. The network manager maintains audio quality for the client device configured or selected to broadcast over the public address system.
