Infinity Diagnostics & Troubleshooting | Pt. 17 Factors that effect media quality

Introduction

This tutorial focuses on diagnosing and troubleshooting factors that affect media quality in Infinity systems, as discussed in Pexip APAC Labs' video. Understanding these factors is crucial for ensuring optimal performance and user experience in video conferencing applications.

Step 1: Understand Key Media Quality Factors

To troubleshoot media quality issues effectively, familiarize yourself with the primary factors that can impact performance:

• Network Conditions: Latency, bandwidth, and packet loss can drastically affect video and audio quality.
• Hardware Limitations: Ensure your devices meet the necessary specifications for running Infinity applications efficiently.
• Configuration Settings: Review codec settings, resolution, and bitrate configurations to ensure they align with your network capabilities.

Step 2: Analyze Network Performance

Conduct a thorough analysis of your network to identify potential issues:

1. Run a Speed Test:

   • Check your upload and download speeds.
   • Ensure that the speeds meet the recommended requirements for video conferencing.

2. Monitor Latency:

   • Use tools like Ping or Traceroute to measure latency to critical servers.
   • Aim for latency under 150 ms for optimal performance.

3. Check for Packet Loss:

   • Use network monitoring tools to identify packet loss.
   • Address any identified issues, such as network congestion.

Step 3: Evaluate Hardware Specifications

Ensure that your hardware meets the demands of the Infinity system:

• Review CPU and RAM Usage:

  • Check if the CPU and RAM are being fully utilized during calls.
  • Upgrade hardware if necessary to improve performance.

• Update Drivers and Firmware:

  • Regularly update the drivers for your audio and video devices.
  • Ensure the firmware for routers and switches is current.

Step 4: Optimize Configuration Settings

Proper configuration can significantly enhance media quality:

• Adjust Codec Settings:

  • Use codecs that balance quality and bandwidth, such as H.264 or VP8.

• Set Appropriate Resolution and Bitrate:

  • Match the resolution and bitrate to your network's capabilities.
  • Consider lowering settings for poor network conditions.

Step 5: Test and Monitor

After making adjustments, conduct tests to evaluate improvements:

• Conduct Test Calls:

  • Perform test calls to verify audio and video quality.
  • Use feedback from participants to identify remaining issues.

• Implement Continuous Monitoring:

  • Use monitoring tools to continuously assess media quality during calls.
  • Be proactive in addressing any new issues that arise.

Conclusion

By understanding the factors that affect media quality and systematically addressing them, you can significantly enhance the performance of Infinity systems. Regular monitoring and adjustments based on network and hardware performance will lead to a better user experience in video conferencing. For further improvements, stay updated with the latest technology and best practices in media quality management.
