Video: How Video is Affected by Human Physiology

Posted on 18th June 2019 by Russell Trafford-Jones

How can we make video more appealing to humans? We’ve evolved to live a certain way and this has defined – and will continue to define – our video technologies. MUX founder Jon Dahl talks to us here about the ways in which human physiology drives viewing habits.

Vertical vs. horizontal video, angular resolution and how the typical viewing distances of computers, TVs and other devices affects what resolution we can perceive are all discussed. Jon moves on to frequencies both of audio and video where frame rates and flicker are important and where physics comes into play alongside biology.

Even for the experienced, this talk is bound to bring something new and is a great tour of the fundamentals of the visual perception that our industry relies on and strives to please day in, day out.

Video: Low Latency and High QOE for Live Streaming

Posted on 16th June 2019 by Russell Trafford-Jones

Low latency streaming is always a compromise, but what can be done to keep QOE high?

This on-demand webinar looks at CMAF and presents some real-world data on this low latency technique. The webinar starts by explaining that CMAF is a low-latency streaming technology similar to HLS and other streaming protocols where the idea is to deliver the video as small files. Olivier and Alain from Harmonic explain how this is done and look at some of the trade-offs and compromises that are needed and introduce techniques to keep QOE high. They also look at deployment in cloud vs. on premise.

Pieter-Jan Speelmans talks about play tradeoffs and optimisations within the player. CMAF allows the buffer to be reduced and whilst a bad network may mean you buffer is similar to ‘normal’, but in good networks, this buffer can be brought down significantly. He also talks about how ABR switching is impacted by GOP length even in CMAF.

Viaccess-Orca explains how DRM works with CMAF and looks at some of the challenges including licences acquisition time and overloading licence servers at the beginning of events. Akamai’s Will Law explains some benefits of CMAF and the near-real-time of chunk-based transfer (HTTP 1.1) and how downloading chunks at full speed leads to problems when the same broadband link is used by several clients.

There are lots of good talks on CMAF, but this is one of the few which talks about CMAF not as theory, but as is deployable today.

Video: Edit Intelligence In Production Pipelines

Posted on 14th June 2019 by Russell Trafford-Jones

Netflix has famously moved in to original content but less-known are its innovations behind the scenes in production workflows.

Eric Reinecke looks at the challenges in moving media and finding ways to correctly pick and choose the right media to move. He looks at the different ways of moving editorial data: the venerable EDL, Avid’s more recent AAF and Final Cut’s XML talking about the pros and cons of them all.

The talk then moves on to OpenTimelineIO which is an API and interchange format for editorial cut information which was designed to help departments in animation studios to work together. Hosted by Pixar, companies like Netflix are finding uses for the API outside of animation and Eric shows demos of how he’s using it within Netflix then ends with a call to get involved!

Webinar: New Goals for Innovating Live Sports

Posted on 13th June 2019 by Russell Trafford-Jones

Sports broadcasting has always been on the forefront of technology both by developing products specifically for the sporting market such as sports graphics, annotation and ball tracking and also by pressing nearly any new technology that comes along into production.
The result of this relentless thirst for technology is year-by-year better and better productions done in more innovative and often lower-cost ways.

Remote production has long been a buzz word in sports broadcasting which has taken a long time to take hold (known as REMIs in North America). This is partly because the technologies needed to do it really well and really seamlessly are only just becoming dominant and partly because sports workflows from a technology and a business needs perspective are so different from company to company that one remote production.

However there are ever stronger pushes into remote production which very much brings remote production into day-to-day use in many companies. Kiswe Mobile joins us on this webinar to explain their experience in enabling remote production.

AI is looked on as an important tool in sports broadcasting. With so much data, both visual and textual, AI will increasingly be an excellent tool to parse and interpret these large data sets. Whether this is simply to produce better stats analytics or to comb through the thousands of hours of footage looking for, and logging, interesting events between players, ball possession stats etc.

IBC brings in Jérôme Wauthoz from Tedial and production consultant Mike Ruddell to bring us their experience making the sports on our screens as great as it can be at a cost that broadcasters can afford.
