Video: IP For Media Webcast Part II

Posted on by Russell Trafford-Jones

Following on from last week’s post part II is here. Wes Simpson looks at use of IP in Remote Production/Remote Integration (REMI) and finished with a panel discussion including Newtek and Grass Valley, a Belden brand.

This video talks about:

  • Why Broadcasters need networking?
  • Typical Live remote sports broadcast roles
  • Overview of video & audio Signal types
  • HDR & Wide Colour Gamut (WCG)
  • Data (metadata, scripts etc)
  • REMI – Remote Integration, AKA ‘Remote Production’ in Europe.
  • Overview of what tasks can be done at base, what still needs to be done ‘on-site’
  • Uncompressed formats summary (SDI, 2022-6, 2110)
  • Slice-based compression
  • Mezzanine compression
  • TR-01 for carrying JPEG 2000 & audio
  • Bonded Cellular
  • Packetloss & FEC (Forward Error Correction)
  • 2022-7 – route diversity
  • Typical delays
  • Plus a panel discussion

Video: Spectral Quality – Improving Colors to Improve Videos

Posted on by Russell Trafford-Jones

Vimeo’s Vittorio Giovara discusses ways to improve viewer retention by improving videos paying attention to colour space and colour volume. This talk covers how and why High Dynamic Range (HDR) works, Wide Color Gamut (WCG), 10-bit vs 8-bit video and also discusses the importance of frame rate on viewer retention.

After all, 4K has gotten most of the headlines, but there are other ways to improve the quality of your streaming video that have even more visual impact. This talk explores video colorimetry, ranging from video quality concepts to the latest trends in the industry. Vimeo’s experience is used as a practical implementation example and showcases how new compression technologies are deployed for the benefit of creators and their audiences.

This isn’t just about pretty videos, Vittorio shows the economic benefits of producing a better product.

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)

Meeting: Are Existing Broadcast Formats Suitable for HDR WCG Content?

Posted on by Russell Trafford-Jones


Date: Thursday November 30, 2017 – Ample Refreshments from 18:15 GMT for 19:00 start.
Location: Ericsson Television, Strategic Park, Comines Way, Hedge End, Southampton, SO30 4DA. Google Maps

With higher resolution, wider colour gamut and extended dynamic range, the new Ultra High Definition TV (UHD) standards define a container which allows content creators to offer the consumer a much more immersive visual experience. However there are some artefacts noted within the container particularly around HDR material. Olie Bauman outlines why YCrCb are used and the human vision systems response to changes in chroma/luminance and the correlation between R, G and B

As HDR and WCG expand the Colour Volumes he will show why these increased from SD (601) to HD (709) to UHD (2020) and show the difference between PQ (Display Referred) and HLG (Scene Referred) workflows

From this background he will show examples of artefacts due to chroma down-sampling and show the different characteristics – depending on work flow.

He highlights that the problems will become greater as more content exploiting the full UHD container becomes available, requiring additional care and processing in content production and delivery.
