Behind the Scenes of Video Streaming: Measuring Video Quality
This seminar from the Cambridge Computer Lab explores the technical underpinnings of video streaming, examining how objective and subjective metrics are used to measure video quality and inform adaptive bitrate algorithms for optimal user experience.
Behind the scenes of video streaming: How is video quality measured Have you ever wondered how Netflix or YouTube decides what video quality you see when your internet connection changes? This talk takes you behind the scenes of video streaming to explore how “video quality” is measured and used to deliver the best possible viewing experience. We’ll examine how streaming services automatically switch between different video qualities, why this matters, and how engineers determine what looks “good enough.” You’ll also discover how human vision plays a key role in judging video quality, and how algorithms are designed to predict which quality degradations human observers will be able to notice and which will disrupt their viewing experience.
