Video: An overview on 10-bit video — UHD, HDR and Coding Efficiency

Posted on by Russell Trafford-Jones

In the past few years, the industry has been trying to improve the end user experience to have a higher spatial (pixels), temporal (framerate) and spectral (bitdepth) resolution.

This talk from Vimeo’s Vittorio Giovara and Ronald Bultje from Two Orioles will explore the high-bitdepth element of this improved user experience. Technically, this is usually referred to as 10-bit video, since, historically, the video user experience has been largely based on a 8-bit world. We will explain marketing terms like HDR, UHDTV, explore high bitdepth-support in commonly used video coding software, and showcase how these work together to improve your video coding efficiency and end user experience.

Introduction: Josie Keller (JWPlayer)
Presenters: Vittorio Giovara (Vimeo), Ronald Bultje (Two Orioles)

Video: Producing 4K/UHD using IP and 12G-SDI

Posted on by Russell Trafford-Jones


Held a couple of months before SMPTE 2110 was ratified at IBC, this panel discussion with Riedel, Evertz, EVS and Grass Valley looks at the state of SDI and IP: Which technologies are relevant now and which will win in the long run?

    The conversation covers these topics and more:

  • 12G Vs 3G SDI
  • Versions of UHD SDI
  • When should a vendor implement IP?
  • Will the future include compression?
  • How do you handle variable latencies with compression?

With the first all-IP and 12G-SDI OB trucks beginning to hit the road, and an increasing number of broadcast centres implementing comprehensive IP-based or hybrid infrastructures, this discussion will focus on the issue of connectivity and whether it is advantageous to use SDI or IP infrastructures – or indeed hybrid approaches utilising both. This panel discussion discussed the imperatives behind this dramatic technological change, the challenges that it presents, and the probable roadmap for the next few years. There will also be analysis of current industry initiatives such as AIMS and the ways in which these can help smooth the transition.

This Panel was part of the Broadcast Innovation Day hold by Broadcast Solutions GmbH.
Participants:
Laurent Petit, VP Products, EVS
Simon Reed, Managing Director, Evertz UK
Thomas Riedel, CEO, RIEDEL Communications GmbH & Co. KG
Phil Myers, Former IP Product Manager, Grass Valley (formerly Snell Advanced Media (SAM))
Moderation: David Davies, Managing Editor, SVG Europe

Video: Why 4K Lenses Are Important Even If You’re Not Doing 4K

Posted on by Russell Trafford-Jones

Mark Schubin presents a talk on why 4K lenses are relevant to HD productions. Starting by discussing whether there is a fixed ‘Television Viewing Distance’ and whether people can see 4K, he continues to discuss the importance of contrast in the ability of humans to see fine detail. Mark looks at Mean Transfer Curves which show that higher resolution lenses allow much more contrast at HD resolutions.

This talk was given at NAB 2018 at the Fujinon stand.

Webinar: Compression Economics

Posted on by Russell Trafford-Jones


Date: Today, 23rd July, 2018 16:00 BST / 8am PST

This joint webinar from the IABM and V-Nova, will dive into the current state of the compression market, exploring new technologies and assessing compression costs and benefits to broadcasters, operators and OTT providers.

“More with less,” this has always been the compression mantra since the beginning. With the rise of new media and the emergence of immersive formats such as UHD and VR, compression vendors have been again asked to deliver better quality at a reduced bit-rate.

    Topics include:

  • Industry trends driving demand for improved video compression
  • Shift from hardware to software (and virtualisation) – impact on compression vendors and benefits for operators
  • The benefits of next-generation video compression for AVOD and SVOD services. What are the dynamics? How much of an effect can it have on a streaming video business?
  • The rise of AI – how artificial intelligence can improve compression economics
  • Immersive formats – UHD/VR demand by end-users; economics of delivering these formats and how best to do so
  • HEVC, AV1 and PERSEUS Plus – the various factors dictating what codec to choose and in which scenarios they have most value
