Measurement/QoE

As the video streaming industry continues to mature, QoE expectations continue to rise in importance both as a value proposition to the consumer as well as a differentiator between competing video streaming services. Yet, consistent, systematic, standardized, objectively measured, and business-rules-driven QoE assurance continues to be an elusive goal. This document outlines factors that impact consumer QoE, sheds light on some of the underlying challenges to diagnosing QoE impact and provides a set of best practices for end-to-end QoE monitoring in video streaming workflows.

This document describes key network delivery metrics for streaming Internet video. The Streaming Video Technology Alliance Quality of Experience (QoE) working group (WG) developed these metrics as a common language to describe effectiveness of network delivery. Although many more metrics could have been documented, these particular metrics represent the most common and important metrics according to the QoE WG group membership. It is expected that these metrics can be used across the streaming video ecosystem to provide guidance that can lead to enhancement of QoE.
