Webinar: Frame Accurate Video Routing with IP-based Broadcast Infrastructure

Posted on by Russell Trafford-Jones


On-demand Webinar
Network performance and programmatic control are integral to building an effective IP infrastructure for the broadcasting industry. In this webinar Arista Networks and Lawo give a technical deep-dive on the next-generation of Broadcast technology and how they can help you to leverage Ethernet Economics in the broadcast plant. This recorded, live webinar will help you to understand:

  • Requirements for studio production and remote production.
  • Requirements for edge conversion, control systems, and seamless switching.
  • The difference between source timed and destination timed switching.
  • The importance of an orchestration layer for the network and broadcast infrastructure.
  • Network requirements for a high-performance broadcast plant:
    • Comprehensive network control via API’s
    • Low-latency and high throughput
    • Wire-rate multicast
    • Accelerated multicast control
    • Flow steering in a source-timed model
    • SDN: the necessity for complete programmatic control

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.
