What is the Mean Opinion Score for video?
The Mean Opinion Score (MOS) is a single number that summarizes the quality of a video playback — all automatically, using modern algorithms.
The MOS includes all aspects of a video session like:
- Initial loading delay (startup time)
- Stalling events happening during the playback
- The fluctuation of audio and video quality over time
The MOS serves as an easy-to-understand indicator for the overall service quality, as experienced by the user. It fully considers the user’s perception.
Due to advanced algorithms that factor in different Key Performance Indicators (KPIs), you can gather MOS values without having to ask users for their opinion. Roll out large scale measurements knowing that the MOS can serve as a proxy for customer happiness.
Together with the MOS, you get all underlying diagnostic data and the usual QoS measures to help you perform root cause analyses for service problems, such as loading times and network statistics.
Complex inputs — but easy to understand. The Video MOS.
