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.

When it comes to IP, audio has always been ahead of video. Whilst audio often makes up for it in scale, its relatively low bandwidth requirements meant computing was up to the task of audio-over-IP long before uncompressed video-over-IP. Despite the early lead, audio-over-IP isn’t necessarily trivial. However, this talk aims to give you a heads up to the main hurdles so you can address them right from the beginning.
Matt Ward, Head of Video for UK-based Jigsaw24, starts this talk revising the reasons to go audio over IP (AoIP). The benefits vary for each company. For some, reducing cabling is a benefit, many are hoping it will be cheaper, for others achievable scale is key. Matt’s quick to point out the drawbacks we should be cautious of, not least of which are complexity and skill gaps.
Matt fast-tracks us to better installations by hitting a list of easy wins some of which are basic, but a disproportionately important as the project continues i.e. naming paths and devices and having IP addresses in logical groups. Others are more nuanced like ensuring cable performance. For CAT6 cabling, it’s easy to get companies to test each of your cables to ensure the cable and all terminations are still working at peak performance.
Planning your timing system is highlighted as next on the road to success with smaller facilities more susceptible to problems if they only have one clock. But any facility has to be carefully considered and Matt points out that the Best Master Clock Algorithm (BMCA).
Network considerations are the final stop on the tour, underlining that audio doesn’t have to run in its own network as long as QoS is used to maintain performance. Matt details his reasons to keep Spanning Tree Protocol off, unless you explicitly know that you need it on. The talk finishes by discussing multicast distribution and IGMP snooping.

Data-driven insights can empower decision makers to enable a better online viewing experience for their audience, optimize their business, and create a competitive advantage in the industry. When it comes to online streaming, there are key metrics you should review to ensure audience engagement and provide high-quality experiences.
This webinar will provide insight into how you can leverage data, addressing the following topics:
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.
