Abstract: With the publication of version 2.0 of the IEEE 1588 Standard for accurate time transfer over packet networks in 2008, the Precision Time Protocol (PTP) quickly became the only viable clock synchronization technology for all application domains relying on ethernet as a transport medium. PTP was deliberately defined in highly generic terms, allowing it to be tailored to application-specific requirements via PTP profiles. The SMPTE ST 2059–2 standard is the PTP profile for the broadcasting industry and a crucial element for any all-IP studio deployment. In 2019, the IEEE published a new version of the IEEE 1588 standard (PTP v2.1), where PTP was enhanced with several interesting optional features aimed primarily at improving the overall reliability of PTP, especially for larger deployments. In this article, we explain all major new features of PTP v2.1 and investigate to what extent broadcasting applications may benefit from adopting them as part of a new version of the ST 2059–2 PTP profile. Specific focus will be put on possible implications with respect to implementation efforts and operating requirements. We analyze whether the overall reliability of PTP can be improved by adding new features such as PTP security or extended monitoring. The high-accuracy extensions to PTP v2.1 will be described together with a rough effort estimate required to develop and deploy products supporting subnanosecond accuracy. The article concludes with a list of recommendations summarizing the benefits of these new features for deploying broadcasting networks at scale.

bio
Nikolaus Kerö received a master’s degree in communication engineering with distinction from the Vienna University of Technology, Vienna, Austria. After graduating, he led the ASIC design division at the University’s Institute of Industrial Electronics, successfully managing numerous research projects and industry collaborations. His research activities centered on distributed systems design, especially highly accurate and fault-tolerant clock synchronization. In 2001, he co-founded Oregano Systems Design & Consulting Ltd., Vienna, Austria, as a university spin-off. While offering embedded systems design services to customers, Oregano transferred the group’s research results into a complete product suite for highly accurate clock synchronization under the brand name syn1588, for which he manages both development and marketing. Oregano Systems is located in Vienna, Austria; in 2019 it has been acquired by Meinberg. He is an active member of the IEEE 1588 standardization committee and the SMPTE 32NF standards group and holds frequent seminars on clock synchronization for both industry and academia.

Thomas Kernen is a principal architect at NVIDIA, Zurich, Switzerland. His main area of focus is defining architectures for transforming the broadcast industry into an all-IP infrastructure. He is a SMPTE Fellow, a standards director, a former chair of SMPTE’s 32NF Technology Committee, and a member of the IEEE Communications and Broadcast Societies. He also served as an editor of the Digital Video Broadcasting (DVB), Geneva, Switzerland TS 101 154 “Specification for the use of Video and Audio Coding in Broadcasting Applications based on the MPEG-2 Transport Stream” supported by millions of digital receivers worldwide. Additionally, he authored more than 20 publications in leading journals and holds multiple patents that cover network, timing, and video coding optimizations for media transport and delivery. He is a frequent speaker at leading industry events both in the broadcast and networking industries. Prior to joining Mellanox, (acquired by NVIDIA), he spent over 20 years in the IP industry including driving Cisco’s entry into live media production, founding Internet Service Providers, Telecom carriers, and architecting Fiber to the Home networks.
