Webinar: The Early Adopters: Inside the latest IP-based facilities

Posted on by Russell Trafford-Jones


Webinar & On demand: 6th December 16:00 GMT
Real-world experience of implementing IP from BBC Wales, Rhode & Schwarz, BCE, SMPTE’s Bruce Devlin examining how broadcasters and suppliers are meeting this transition and what real-world benefits the IP revolution can bring broadcasters, vendors and audiences.

SMPTE UK Governor and incoming SMPTE Standards VP Bruce Devlin will be joining Roger Crothers Head of Technology BBC Wales, Costas Columbus Manager Major Projects BCE and David Smith R&S to discuss the switch from SDI to IP-based broadcast studios which is now well under way.

On-demand Webinar: “It’s about time” SMPTE ST 2059 Network-Delivered Reference

Posted on by Russell Trafford-Jones

The SMPTE ST 2059 standards suite provides a method to accommodate all legacy reference and media signals using IEEE-1588 Precision Time Protocol (PTP), delivered over an IP network. This webcast examines how this new way of synchronizing systems will affect legacy, hybrid, and future all-IP infrastructures.

Beginning with an overview of PTP, Paul Briscoe demonstrates how the ST 2059 standard uses this foundation to establish deterministic relationships between global real-time and media signals. It explores how equipment using PTP meets synchronisation requirements instead of legacy reference signals and how timecode is virtualized. The webcast then examines product design considerations for hybrid environments, focusing on how a common reference subsystem can use either legacy or hybrid forms of reference, enabling equipment to evolve alongside user requirements. An explanation on how ST 2059 brings together legacy and new systems for this new method to be applied to live IP infrastructures will be offered. The webcast closes with a discussion on system design considerations, focusing on ways to incorporate technology islands in a hybridised architecture.

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.

The broadcast industry is in the process of transitioning to IP based transport for video, audio, and data. This has led to the development of standards including SMPTE ST 2022-6 that provide encapsulation of uncompressed SDI within IP packets and the SMPTE ST 2110 suite of standards for Professional Media Over Managed IP Networks.

These standards provide the interconnection framework for an all-IP infrastructure within a facility. The way in which these data packets flow across the network requires a variety of protocols to send this information bi-directionally from the source to the destination. Requiring broadcast engineers to gain an understanding of the technology and the new techniques needed to monitor these signals.

In this webcast, we will examine the basic structure of the packets for ST 2022-6 and the ST 2110 suite and how variable delay across the network introduces jitter at the receiver and how measurements can be made on the stream. Latency in the network can produce out of order packets or corruption of the data causing packets to be dropped. Therefore, it is critical to monitor the stream to ensure an eerror-free network to ensure transmission of the high bit rate media and how these errors affect the actual video and audio signal. For redundancy in the media network SMPTE ST 2022-7 can be used to provide a Path One and a Path Two stream that the downstream device can determine which path is the most appropriate to use. Measurement of the integrity of both paths is important and we will look at ways of monitoring the signal paths.
