Video: How to Fine Tune your Adaptive Encoding Groups with Objective Quality Metrics

Posted on by Russell Trafford-Jones


In this on-demaind video, Streaming Learning Center’s Jan Ozer explains objective metrics to us and how they can be used to build better ABR ladders.

Choosing the number of streams in an adaptive group and configuring them is usually a subjective, touchy-feely exercise, with no way to really gauge the effectiveness and efficiency of the streams. However, by measuring stream quality via metrics such as PSNR, SSIMplus, and VQM, you can precisely assess the quality delivered by each stream and its relevancy to the adaptive group.

This presentation identifies several key objective quality metrics, teaches how to apply them, and provides an objective framework for analyzing which streams are absolutely required in your adaptive group and their optimal configuration.

Video: Reducing Latency & Startup Times

Posted on by Russell Trafford-Jones


Low latency and fast startup times are KPIs for most streaming video producers, particularly for live events. In this talk from Streaming Media west, you will learn how to achieve the low latency live streaming.
David and Jun show the importance of measuring startup time, latency, and network overhead and with Jan Ozer, they show you how to get latency down by:
• reducing fragment sizes, using hybrid fragment sizes;
• specifying first variant retrieved;
• controlling the number of fragments retrieved before playback starts;
• and opening a persistent connection between player.

You’ll learn the most effective strategies for minimizing startup time and latency without swamping your network with additional HTTP requests, and what you’ll need to do to implement them in your encoding and delivery workflows.

David Hassoun, CEO RealEyes Media

Location: Pincents Manor, Pincents Lane, Calcot, RG31 4UQ View Map

A panel of experts covers two topics: NAB and the power of diversity.

NAB saw an sharp uptick in AI-based products, big names moving around the floor and a 10% drop in attendance. This meeting explores whether that impacted the NAB experience and if we are seeing any evidence of that in our businesses. Does it affect your decision on attending industry shows? Why do you think less people are attending? Or is it now quality over quantity? The panel will discuss with an open Q&A at the end for feedback.

The evening will also discuss diversity in the workplace. With industry manufacturers and suppliers having less than 2% female CEO’s – where is the diverse workforce? Is there an opportunity for them? What can companies do to ensure a more diverse workforce? What are the benefits?

Book now as this is always a popular event and numbers are limited.

Video: Streaming at 250 kbps – raise your expectations

Posted on by Russell Trafford-Jones


Megha Manohara discusses Netflix’s ongoing efforts to reduce the bitrate of movies whilst maintaining their enjoyability showing their success right down to 250kbps.

As a Senior Software Engineering on Video Algorithms, Megha’s talk focuses on the research and implementation challenges of Dynamic optimizer – an innovative shot-based encoding tool that raises the perceptual quality of streams at bitrates as low as 250kbps. Visiting VMAF, PSNR and other metrics on the way, this talk gives great ideas on reducing bitrate and measuring success.
