The Programmable Video Network Quality API is a solution for web developers to evaluate and share network quality data with end-users, helping to identify the root cause of degraded video conferencing quality. The API provides a simple way to communicate network quality levels on a Likert scale from 5 (very good) to 1 (very bad), allowing users to understand why they are experiencing poor quality. This can help reduce frustration and complaints from end-users, while also enabling them to take steps to improve their network connection. The API is designed to work with WebRTC developers, providing a powerful tool for diagnosing network-related issues and improving the overall video conferencing experience.
