Class: Pragmatism In Engineering

---

A couple of years ago, Hermann Popp from ARRI came to me and talked about putting MXF in ST 2110. My initial take away was that his proposal felt like exactly the right way to solve the problem he presented, but was completely counter-intuitive to the IP Engineering purists who would push back on the concept of double wrapping the content. It took...

‘As hybrid workflows that bridge the IP and SDI worlds become the norm, test and measurement tools that support hybrid environments become increasingly more important’ says PHABRIX’s Martin Mulligan, SVP Sales and Operations. With the industry’s steady migration from traditional HD-SDI to IP and/or 12G-SDI infrastructures, broadcasters are now face...

IP Technology for Broadcast Audio Routing Systems

---

As the AoIP debate continues to confuse and delight in equal measure, what is clear is different scenarios require specific solutions. So is there a solution that encompasses open standards and existing proven AoIP technologies to the benefit of all?IntroductionBy definition, network infrastructure (switches, routers and cables) is protocol and tec...

What is the JT-NM Tested Program

---

The National Association of Broadcasters (NAB) Show 2019 has come and gone with the usual onslaught of product announcements, launch parties, demonstrations and the usual high-density crowds preventing any high-speed movement between halls. The IP showcase, this year, featured a JT-NM tested program. If you're unfamiliar with the JT-NM, then it's w...

It\'s that time of year again. 06:30 on road bikes on the Las Vegas Strip with a merry bunch of folks who believe they look good in lycra. As we pedal West up the hill towards Red Rock there will be stories of the year just gone and questions about what to look for at the show. I, for one, will be attending the Devoncroft event to check up on who i...

The Pace of Change

---

The youngest human to stand on the moon (so far) was Charles Moss, the lunar module pilot of Apollo 16. Charlie had a wonderful claim: his father witnessed the Wright Brothers’ first flight at Kitty Hawk, and lived to see his son on the moon. Does anything capture the speed of technological advance better than that? The whole of the history of powe...

Why is ST2110 important

---

Presenting to a capacity audience at a joint meeting of the RTS Thames Valley Centre and SMPTE in Reading, research engineer and industry commentator Tony Orme opened the evening with the assertion - “SMPTE’s ST2110 is the most important development to hit broadcast television since John Logie Baird went head to head with EMI-Marconi at the 1936 BB...

Moving to an IP Platform Considerations

---

Audio transport methods have remained virtually unchanged in the broadcast industry for more than half a century. Common approaches to routing audio around large broadcast facilities have closely followed methodology employed in telco central offices, with the use of X-Y crossbar or crosspoint switching. This began to change with the arrival of sol...

Listening to the needs of audio engineers

---

Monitoring SDI video content within an installation is and has always been straight forwards. If you have a monitor, and you can see the image correctly, all is well. This is not necessarily the case for metadata and especially not for audio. Assuming a SMPTE 352 payload packet is present on the SDI signal, this metadata determines how the video co...

Class: Do we still need standards

---

On the 1st January 2018, I officially took on the post of SMPTE Standards Vice President. The role has responsibility for all of SMPTE’s standardisation activities and it fills me with equal measures of excitement and terror. A big thank you to Alan Lambshead who, after 4 years as Standards Vice President is handing over the post to me. I think it...
