While the industry was already increasingly moving towards models of remote and distributed working in all aspects of the workflow, the events of 2020 have provided a dramatic accelerant to this trend. The requirements of Covid-mandated social distancing protocols have added to the already compelling economic arguments for remote work, and meant that media organisations are looking for solutions that can accommodate the data flows of the new IP-based broadcast ecosystem reliably and securely with the high performance criteria that broadcast video — especially live broadcast video — requires.
Need for speed: protocols for low-latency broadcasting
Low broadcast latency has become a mandatory requirement in any tenders and competitions for building of head-end stations and CDNs. Previously, such criteria were applied only to sports broadcasting, but now operators require low latency from broadcast equipment suppliers for every sphere: broadcasting news, concerts, performances, interviews, talk shows, debates, e-sports and gambling.
Standards and Specifications… vital for interoperability
We have seen in recent years that the user community is resistant to adopting new technologies unless there is a clear demonstration of interoperability between vendors’ implementations. This is evident from the large number of plugfests that have been held for technologies like IMF, ST 2110, AES67 and ST 2059 suites of standards. There are also efforts such as the NMOS ‘incubator’
to get multiple suppliers together to test concepts before the specifications are designated as ‘stable’.
SMPTE ST 2059-2: Synchronizing Professional Broadcast Networks
Whitepaper from Calnex Solutions:
As IP networks become more prevalent in professional broadcast environments, accurate synchronization using the Precision Time Protocol (PTP) is becoming a critical consideration. This paper provides background on PTP, and details on the SMPTE ‘Broadcast’ Profile.
BaM™ Product Highlight: Broadpeak nanoCDN™
Find out more about Broadpeak’s BaM Award Winning solution, nanoCDN™ with Ultra Low Latency and Device Synchronization.
“Broadpeak’s nanoCDN solution improves live streaming experiences thanks to decreasing the latency. Latency measured in a perfect condition network of a lab, will be the same as a real-life system. It won’t depend on the network condition at a given time. IPTV moving to a full ABR system is a true breakthrough for operators.”
BaM™ Product Highlight: Skyline Communications Dataminer
Find out more about the Support BaM Award® Winner from NAB Show Las Vegas 2019.
“With the integration of PTP and flow management in the DataMiner off-the-shelf platform, media operators have the right solution to successfully make the transition to all-IP and are able to adopt to future workflows that are still unknown”
Next generation digital video transmission via Open IP
Karl So, Vice President, Product Marketing, Caton Technology
Video Transmission requires technology, not a lot of money and effort. This presentation explains how deep learning can predict packet loss during transmission. The transmission end can automatically detect and pre-reissue the “going to be lost” packet before the receiving end asks for it; this will greatly improve transmission reliability.
Fundamentals of PTP – Technical Training
A one day training course that covers the fundamentals of PTP, including the evolution of the standard from version 1 to version 2.
Time compensated remote production in the all-IP world
Ed Calverley – Product Manager, Suitcase TV This session looks at how the current standards work is enabling true end-to-end IP-based production and how standards such as SMPTE ST 2110 enable systems to interoperate in a much more flexible way than was possible with SDI. As an example, during the Euro 2016 soccer tournament a time compensated 2-stage switching solution was frame accurately controlled over a limited-bandwidth link.

Synchronization and the IP evolution
Paul Briscoe – Consultant, Televisionary TV synchronization will migrate to network-based IEEE-1588 Precision Time Protocol (PTP) and the SMPTE ST 2059 Standard for a network-delivered reference needed for live IP. This presentation provides an overview of these standards and how they are applied to media systems, including the virtual generation of legacy signals, how ST2110 systems use PTP natively and how hybrid systems can be designed.
