In some parts of the industry UHD is entirely absent. Thierry Fautier is here to shine a light on the progress being made around the globe in deploying UHD.
Thierry starts off by defining terms – important because Ultra HD actually hides several, often unmentioned, formats behind the term ‘UHD’. This also shows how all of the different aspects of UHD, which include colour (WCG), HDR, audio (NGA) and frame rate to name only a few, fit together.
There’s then a look at the stats, where is HDR deployed? How is UHD typically delivered? And the famed HDR Venn diagram showing which TVs support which formats.
As ever, live sports is a major testing ground so the talk examines some lessons learnt, and features a BBC case study, from the 2018 World Cup. Not unrelated, there is a discussion on the state of UHD streaming including discussion of CMAF.
Leading nicely onto Content Aware Encoding (CAE), which was also in use at the world cup.
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.
This talk was given at Streaming Tech Sweden which is an annual conference from Eyvinn Technology. Streamed on their own video platform, talks are initially available exclusively to all conference attendees, but are released free-to-view during the subsequent year. Free registration is required to watch the videos.
Server-Side Ad Insertion (SSAI) it’s the best defence against ad-blockers, but switching in an ad at source can be tricky particularly in low latency streams. This talk at the OTT Leadership Summit at Streaming Media East brings together leaders in the field to explain where they’re up to in delivering this technology and the benefits they see.
Magnus Svensson tells us about the instrumental role Eyevinn Technology, the consultancy who run the technical conference Streaming Tech Sweden , is played in Sweden creating an open standard for all the broadcasters to work to in order to agree how to track SSAI allowing the correct payments to be made. Magnus also talks about aligning SCTE insertion with MPEG structure and the importance of correct preparation of the source video.
Tony Brown from Newsy talks about the centralised nature of SSAI making management easier and gives ana overview of decisioning bringing together buys and sellers of ads. Tony also discusses other analytics such as adjacency and targeting.
Jason Justman of Sinclair Broadcasting Group, explains SCTE insertion and talks about the technical difficulties in reacting to live changes in programming.
Geir Magnusson, Jr. from fuboTV covers the difficulties of preparing the ads quickly enough for thousands or millions of streams to get customised, SSAI ads at the same time and discusses his strategy to start pre-fetching ads from the ad server to prepare them ahead of time. Geir also highlights the misunderstanding that can exist where streaming provides the same video and programme experience as traditional broadcast but ad buyers don’t all understand how much more targeting is possible – even with SSAI.
In this presentation from Streaming Tech Sweden 2017, Carl Lindqvist from Bonnier Broadcasting and Johan Skaneby from Eyevinn Technology, describe the benefits and gains of using CRF-capped VOD encoding (constant rate factor).
With a thorough explanation of how this encoding works, Carl and Joahan show that CFR Based encoding can deliver
