Articles You May Have Missed – February 14, 2018

As NAB 2018 approaches, engineers and technical managers will focus on how IP technology and solutions need to be incorporated into their facilities. To help The Broadcast Bridge readers make the transition, we publish multiple educational resources each week. Here are two recent tutorials on moving to IP-centric solutions. The first article examines the differences between Precision Time Protocol (PTP) transparent clock and a PTP boundary clock and which may be best suited for your facility. The second resource is a book you can purchase that offers guidance about migrating a broadcast, playout or production facility from SDI-centric to IP-based solutions.

Both SDI and IP facilities require accurate timing to process, route and play-out audio and video media.

Both SDI and IP facilities require accurate timing to process, route and play-out audio and video media.

Precision Time Protocol (PTP) is defined by specification IEEE-1588, which is an algorithm that synchronizes network peripherals with a common time reference. Before PTP, there was the Network Time Protocol (NTP), which allowed systems to be synchronized within a few milliseconds of Coordinated Universal Time (UTC). While that was sufficient for basic time of day information, it is not precise enough for real-time applications like audio and video. To improve accuracy, thus enabling real-time applications to utilize the Ethernet network, the Institute of Electrical and Electronics Engineers (IEEE) defined PTP. 

Here is what you need to know when implementing PTP in your facility, “PTP: Transparent Versus Boundary Clock in Broadcast Environments.”

Need help in bringing your facility into the IP generation? Tony Orme’s book, “Building IP Media Facilities” is where you start.

See that hill up ahead? It’s not a hill, it’s Mt Everest and your job is to conquer that mountain. Rendered into familiar industry vernacular, you, video engineer, are charged with building an IT-centric facility. A SMPTE standard was just approved, so what’s taking you so long?

Faced with such a challenge, some broadcast and production engineers might decide to instead just hang up their ‘scopes. However, for those media engineers who want to be tomorrow’s IP experts, by pushing through to the summit they will become the new technology heroes. Purchase you copy of consulting engineer Tony Orme’s on-line book, “Building IP Media Facilities – Keys to Migrating from SDI.”
