Webinar: Mark Schubin’s “Six Centuries of Opera and Media Technology in New York”

Posted on by Russell Trafford-Jones


Date: 1st November, 2018. 1PM EDT / 10AM PDT / 17:00 GMT

Electronic home entertainment was invented in New York City for opera and so were headphones. The first compatible-color television program seen at home was opera in New York and so was the first bootleg recording. New York’s media technologies for opera date back to the 16th century and in the 21st century include dynamic video warping with depth-plane selection and multi-language live cinema transmissions to all seven continents (first described in a New York newspaper in 1877).

The genesis of much modern tech that we use today in broadcasting – and many business models – had their birth in Opera over a hundred years ago. Find out more!

A 200-ton music synthesizer broadcasting opera music in New York in 1907? An opera lighting dimmer in 1638? Opera for military communications tests?

It may be difficult to believe, but it’s true!

This is a special SMPTE New York-Section National Opera Week webcast event featuring Mark Schubin, esteemed engineer and explainer.

Video: Audio Network Standards AES67 and SMPTE ST2110

Posted on by Russell Trafford-Jones

This is a very accessible overview of AES67 and 2110 from Andreas Hildebrand, evangelist for RAVENNA audio over IP technology at ALC Networx.

Andreas explains what SMPTE 2110 and AES67 are and how they relate to other standards in the industry. He then looks at the timing requirements of 2110 and how they differ to those of AES67 with examples. Another important area examined is when 2110’s audio is/isn’t compatible with AES67.

Finally AES3 is discussed as this is part of the ST 2110-31 standard and Andreas shows how this relates to RAVENNA standards.

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: What is Immersive Audio and Why is it so Cool?

Posted on by Russell Trafford-Jones

With all manner of entertainment using the moniker “immersive”, what does this mean with regard to audio?

This webcast will describe what immersive audio is, why it is so cool, and what makes it vital to the industry. Brian Vessa from Sony Pictures Entertainment will take a deep dive into ST 2098-1, which defines immersive audio metadata and is the first document in the suite of SMPTE immersive audio standards.

Since the introduction of immersive audio to the cinema, SMPTE has been working to create standards to foster interoperability between the many variations of playback systems and the many variations in mixing tools. A number of standards documents have been created that address different aspects of the problem.
