Media Playback IP Conflict Resolution for Synchronized Audio
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing networked media playback systems face challenges in resolving Internet Protocol (IP) address conflicts, which can lead to network instability and synchronization issues among playback devices.
Innovation Solution
The system includes a playback device that monitors network data for IP address conflicts and requests a new IP address from an access point when necessary, while also broadcasting probe messages to other devices to ensure all devices obtain updated IP addresses, using both passive and active resolvers to manage IP address renewal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a playback device uses a static IP address in a networked media playback system, then network configuration is simple and stable, but IP address conflicts occur when devices are added or removed from the network
Solution Approach 1:
The patent implements dynamic IP address resolution by having playback devices continuously monitor the network for IP address conflicts and automatically request new IP addresses from the access point when conflicts are detected. This dynamic approach allows the network to adapt to changing device configurations while maintaining stability through automated conflict resolution mechanisms.
2Adaptability or versatility
If playback devices automatically detect and resolve IP address conflicts, then network adaptability improves, but system complexity increases due to monitoring and resolution mechanisms
Solution Approach 1:
The patent employs self-service mechanisms where playback devices autonomously monitor their own IP address status, detect conflicts when they occur, and automatically request new IP addresses from the access point without requiring manual intervention or complex centralized management systems. This reduces overall system complexity while maintaining high adaptability.
Solution Approach 2:
The implementation includes feedback mechanisms where playback devices continuously monitor network data for IP address conflicts and use this information to trigger automatic resolution actions. The system receives feedback about address conflicts and adjusts its behavior accordingly, maintaining simplicity through reactive rather than proactive complex monitoring.
3Productivity
If IP address conflicts are not resolved, then system operation continues without interruption, but network instability and synchronization issues occur among playback devices
Solution Approach 1:
The patent implements preliminary action by having playback devices proactively monitor for IP address conflicts before they cause network instability or synchronization issues. When potential conflicts are detected, the system automatically requests new IP addresses in advance, preventing problems rather than reacting to them, thus maintaining both continuous operation and network stability.

AI summary
An example method for facilitating resolution of Internet Protocol (IP) address conflicts involves obtaining a first IP address from a host device; monitoring, by a playback device, an input port of the host device for receiving messages and thereby detecting that the host device has received a message comprising a first lease renew request for a second IP address from a device other than the playback device; determining that the first IP address matches the second IP address; after determining that the first IP address matches the second IP address, obtaining a third IP address from the host device, wherein the third IP address is different from the first IP address and the second IP address; and after obtaining the third IP address, (i) obtaining audio content from at least one cloud server via the host device and (ii) playing back the audio content using at least one audio amplifier.
