Video Quality of Experience: Requirements and Considerations for Meaningful Insight
An Industry Whitepaper
Video streaming, whether over-the-top (OTT) applications or on-deck services, accounts for the majority of Internet bandwidth.
There are a range of business motivations for communications service providers (CSPs) to monitor subscriber quality of experience (QoE) for streaming video services. Whether for network engineering purposes, business intelligence insight, customer experience management initiatives, or some other reason, the ability to determine the QoE from the subscriber’s perspective, for each video stream, is of paramount importance.
In fact, with the right solution in place every single video playback is a chance to measure and monitor the subscriber experience on the network; in effect, such a solution turns the entire subscriber base into a dynamic collection of real-time probes.
With the wrong solution—one that’s ignorant of the end user experience or that relies on sampling approaches – then every video playback is a missed opportunity.
By understanding the complexities associated with truly measuring video QoE from the end user perspective – and the requirements that these complexities impose – CSPs will be in a position to make an informed decision and choose the most suitable solution.
This paper explains why, to correctly determine the user’s true QoE for video streaming, a solution must understand how user-initiated actions manifest against a backdrop of observed and expected video streaming behavior, unique to the video application being used – in an environment in which a single video might be split across multiple flows, a single household might be watching multiple videos at once, and the video traffic is encrypted.
