Quality of experience (QoE) metrics

The QoE metric in FastPix quantifies the Quality of Experience (QoE) of video streaming using a single numerical value ranging from 0 to 100. A score of 100 indicates an entirely satisfying experience for all viewers, while a score of 0 signifies a universally frustrating experience. This score is derived from four key performance elements: Playback Success, Startup Time, Playback Stability, and Render Quality. Each video view is assigned an experience score based on these elements, which are then averaged to calculate the Overall Viewer Experience Score.

Why QoE is important?

The Overall Viewer Experience Score is crucial for assessing the effectiveness of video streaming services from the viewer's perspective. It provides a holistic view of how well content is delivered and received, allowing platforms to identify strengths and weaknesses in their streaming performance. By understanding this score, content providers can prioritize improvements that enhance user satisfaction, reduce churn, and ultimately drive viewer engagement.

Using QoE to build video better

To utilize the Overall Viewer Experience Score effectively, analyze it alongside the individual component scores (Playback Success, Startup Time, Stability, and Quality) to pinpoint specific areas for improvement. Monitor changes in the Overall Viewer Experience Score over time to evaluate the impact of optimizations or new content releases.

Additionally, you can compare scores across different videos or time periods to identify trends in viewer satisfaction and make informed content strategy decisions. By focusing on improving this score, platforms can enhance their overall service quality and deliver a better viewing experience.

The formula for the Overall Viewer Experience Score is given by:

Overall Experience Score  = Playback Success Score * (w1 x Stability Score + w2 x Render Quality Score + w3 x Startup Score )
