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.

Video: Making SMPTE ST 2110 installations work

Posted on by Russell Trafford-Jones

Philip Schofield, MD of Crystal Vision and Richard Lawrence the Principal Software Engineer, talk about implementing ST 2110 highlighting how to deal with some of the challenges of putting together a live media IP installation, including network security, firewalls, compatibility between equipment suppliers and new methods of monitoring and synchronisation.

In a SMPTE UK Section meeting held at Crystal Vision, this talk looks at the reasons not to move to IP and the reasons why it makes sense and demonstrates a small IP system, at work. And covers:

  • IGMP issues,
  • Security,
  • Firewalls,
  • Interoperability,
  • Narrow and wide profiles,
  • The new ways of monitoring,
  • PTP and Synchronisation

Plus questions from the audience.

Video: Deep Dive into SMPTE ST 2110-30, 31 & AES 67 Audio

Posted on by Russell Trafford-Jones

Despite the title, a relatively light and short video for the weekend from NAB on using audio in 2110.

Why is there a separate SMPTE ST 2110-30 standard from AES67? Are AES67 devices compatible with SMPTE ST 2110-30? Why is there a SMPTE ST 2110-31 standard? This presentation from Leigh Whitcomb (Architect, Imagine Communications) is a deep dive into the SMPTE ST 2110-30, 31 and AES67 audio and will answer all these questions.

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
