  • Method and system for automatic user quality-of-experience measurement of streaming video
    Patent number: 10673921
    Abstract: Disclosed are system and method that automate measurement of end users' quality-of-experience (QoE) when perceiving the video being streamed to the users' viewing devices. The overall user QoE is measured and computed by combining the instantaneous presentation quality, the playback smoothness quality, and the interactions between them. Prediction accuracy is thus significantly improved. The instantaneous and end-of-process QoE measures created by the system and method described are suitable for the monitoring and optimization of media streaming systems and services.
