Bitmovin have brought together Jan Ozer from the Streaming Learning Center, their very own Sean McCarthy and Carlos Bacquet from SSIM Wave to discuss how best to assess video quality.
Fundamental to assessing video quality, of course, is what we mean by quality, which artefacts are most problematic and what drives the importance of video quality.
Quality of streaming, of course, is interdependent on the quality of the experience in general. Thinking of an online streaming system as a whole, speed of playback, smooth playback on the player itself and rebuffing are all factors of perceived quality as much as the actual codec encoding quality itself which is what is more traditionally measured.
The webinar brings together experience in measuring quality, monitoring systems and ways in which you can derive your own testing to lock on to the factors which matter to you and your business.

A standard in progress for quality of experience networks, rebufereing time etc. Under the CTA standards body wanting to create a standard around these metrics. The goal of the group is to come up with a standard set of player events, metrics & terminology around QoE streaming. Concurrent viewers, isn’t that easy to define? If the user is paused, are they concurrently viewing the video? Buffer underruns is called rebuffering, stalling, waiting. Intentionally focussing on what the viewers actually see and experience. QoS is a measurement of how well the platform is performing, not necessarily the same as what they are experiencing.
The standard has ideas of different levels. There are player properties and events which are standardised ways of signalling that certain things are happening. Also Session Metrics are defined which then can feed into Aggregate Metrics. The first set of metrics include things such as playback failure percentage, average playback stalled rate, average startup time and playback rate with the aim of setting up a baseline and to start to get feedback from companies as they implement these, seemingly simple, metrics.
The Streaming Video Alliance is back with the next in their webinar series and the focus turns to churn.
Viewer churn is the OTT killer. But keeping subscribers engaged and coming back to a service involves more than just great content. It requires a keen eye on the data—from ensuring a great Quality of Experience (QoE) to making smart marketing decisions about content to providing excellent customer service, data is key.
What should you be measuring?
What are the key metrics and their thresholds?
How do you implement all of this into an existing workflow?
This panel will explore the kind of data that can have a meaningful impact on an OTT experience, best practices for measuring different elements within the workflow, and the techniques to capture the data that you need.

How webcasting quality of experience (QoE) and quality of service (QoS) dashboards can provide the most critical information needed to troubleshoot live presentations in real time
How video publishers can use data and analytics in managing and improving their service
How QoE and QoS impact your audience and bottom line
How to drill down to the individual user level to gain 360-degree insight into viewer experience
What metrics and data points are the most important for video publishers and OTT services
How can QoE analytics be used to design streaming infrastructure and improve streaming performance.
