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.

When moving to the All-IP Studio traditional synchronisation techniques like Black-burst or Tri-Level-Sync have to be replaced by a packet based method to make best use of a single shared medium. The Precision Time Protocol (PTP) is ideally suited for this. With the ST 2059 standard SMPTE has defined PTP profile tailored to the needs of the broadcasting industry covering a large variety of different application scenarios ranging from OB-VANs to large studios. Planning, configuration, deployment, and continuous monitoring is crucial for every mission critical application. Nikolaus Kero (General Manager, Oregano Systems) presents experiences gathered from extensive measurements as well as real-world applications demonstrating the performance of PTP under varying network conditions, yet also highlighting traps and pitfalls of PTP which may affect both its availability or accuracy. Different PTP enabled network topologies are compared. This work is a joint effort with Meinberg. [maxbutton id="136" url="https://theiabm.org/wp-content/uploads/2017/10/NikolausKero.pdf"]

As file sizes continue to grow, managing and delivering large files is becoming an important consideration for organizations of all sizes. Companies have abandoned the commonly used FTP/TCP protocol as a delivery method in favor of alternative file transfer solutions which provide acceleration, reliability, management, and security. Companies seeking file transfer acceleration are not limited to the high-tech sector. Organizations leveraging the benefits of acceleration are found in sectors such as media and entertainment, natural resources, supercomputing, legal, health, government, financial, manufacturing, and more. Companies using TCP-based file transfer protocols to transfer large data sets may experience slow file transfers, or even failed and/or corrupt file transfers. This failure rate can be detrimental to organizations moving large data sets on a regular basis. This wastes valuable time, especially if these transfers take hours across an otherwise healthy network. This white paper will address some of the issues organizations encounter when using TCP-based protocols. It will also outline some other common file sharing methods, and the issues inherent with each. It will then outline the FileCatalyst solutions, and how they overcome the issues surrounding slow file transfers. Finally, this paper will present a number of scenarios that showcase the advantages of...
