Video: Synchronization and Timing in SMPTE ST 2110

Posted on by Russell Trafford-Jones

Paul Briscoe explains PTP from the basics taking us through the reasons for using it and how it’s applied to the ST 2110 which to carries uncompressed video, audio and metadata.

The ST 2110 standard brings with it an entirely new way to establish system timing, through use of IEEE-1588 PTP and SMPTE ST2059. This method is native to the IP domain and to the RTP transport and media synchronization used by 2110 but also provides virtualized legacy timing capability.

Paul discusses
• The considerations in system timing using ST2110, including those which include SDI elements.
• How PTP delivers precision time across an IP network
• How ST2059 uses PTP to virtualize any reference signal.
• The synchronization mechanisms of ST2110 including transport timestamps and media clocks
• How streams are synchronized among each other and how they interoperate with PTP
• How timing of SDI and AES3 signals is harmonized with ST2110 streams.
• Router switchpoint timing and latency considerations.

Meeting: IP in Broadcast

Posted on by Russell Trafford-Jones


Meeting: 17th Jan 2018 | 17:00 | 8 Golden Square, Soho W1F 9HY
An exclusive presentation and demonstration to help you get to grips with Precision Time Protocol (PTP) and IP workflows from Daniel Boldt (Head of Software Development, Meinberg) and Nikolaus Kerö (General Manager, Oregano Systems).

If you’re thinking about upgrading to an all-IP studio workflow, traditional synchronisation techniques like black burst and tri-level sync will have to be replaced with a packet-based method in order to make best use of the new single, shared medium. PTP is ideally suited to this, and the SMPTE 2059 standard has helped define and tailor PTP to the needs of the broadcasting industry.

Of course, planning, configuration and continuous monitoring are essential for every studio’s mission critical applications, especially if you’re upgrading to an IP-based infrastructure. As part of an in-depth presentation around PTP and IP workflow, Daniel and Nikolaus will be discussing their experiences of working with the new technologies, and comparing different PTP-enabled topologies. They’ll also provide a real-world demonstration of IP-based applications to showcase the performance of PTP under varying network conditions, and highlight its pitfalls, which could affect availability and accuracy further down the line. As standard, there’ll be drinks so you can network and discuss all the evening’s topics with everyone afterwards.

What to expect…
5pm Registration.
5.30pm Presentation begins.
8pm Drinks and networking.

Webinar: Intro IP Video and PTP Timing Webinar

Posted on by Russell Trafford-Jones


On-Demand Webinar: 21 Minutes
Starting with an overview of the different approaches to uncompressed video over IP, Paul Robinson, then CTO of Tektronix, explains how PTP works and how it is applied in practice. Finishing with a Q&A, these topics are all still relevant in a post SMPTE 2110 world. ST 2110 was built on some of the technologies discussed separately in this talk from 2016 and much can be gained from this understanding.

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.
