WHITE PLAINS, N.Y. — Nov. 29, 2017 — SMPTE®, the organization whose standards work has supported a century of advances in entertainment technology and whose membership spans the globe, today announced the publication of the “Report of the Study Group on Flow Management in Professional Media Networks.” The new, 52-page report investigates current and future technologies for media content flow management in professional media networks (PMN), explores user requirements, examines potential transmission methods for management commands, provides an overview of existing standards and specifications now available to the professional media industry, and offers a series of recommendations to the industry including some for future work.
“The Study Group report delves into critical considerations for establishing effective, interoperable flow management across IP networks,” said Howard Lukk, SMPTE director of engineering and standards. “Based on the expertise of SMPTE Members and input from across the industry, the report offers a solid foundation on which to build future standards work — and thereby accelerate the industry’s shift toward more efficient, scalable, agile, and flexible IP infrastructures and workflows.”
Flow management is the mechanism for controlling how real-time media flows are guided through a fabric of Ethernet switches from senders to receivers with the appropriate functionality of media clean switching, reserved media bandwidth, and guaranteed required quality of service (QoS). Ideally, operators managing flows within internet protocol (IP) infrastructure should be able to use router panels and interfaces from the familiar serial digital interface (SDI) infrastructure, but the industry has yet to put forward the necessary underlying professional-grade protocols and mechanisms for this purpose. While work is already in progress within some organizations, open standards are not yet available.
The SMPTE report addresses the gap in existing standardization and ultimately makes recommendations for SMPTE standards work in the areas of QoS profile, congestion management, and authentication in PMN. It also discusses the need for harmonization of device control protocol standards currently available to the industry. Recommendations for the broader media industry include topic areas such as flow switching methods, software-defined networking (SDN) control, and anomaly detection.

About the Society of Motion Picture and Television Engineers® (SMPTE®)
For more than a century, the people of SMPTE (pronounced “simp-tee”) have sorted out the details of many significant advances in media and entertainment technology, from the introduction of “talkies” and color television to HD and UHD (4K, 8K) TV. Since its founding in 1916, SMPTE has received an Oscar® and multiple Emmy® Awards for its work in advancing moving-imagery engineering across the industry. SMPTE has developed thousands of standards, recommended practices, and engineering guidelines, more than 800 of which are currently in force today. SMPTE Time Code™ and the ubiquitous SMPTE Color Bars™ are just two examples of SMPTE‘s notable work. As it enters its second century, SMPTE is shaping the next generation of standards and providing education for the industry to ensure interoperability as the industry evolves further into IT- and IP-based workflows.
SMPTE‘s global membership today includes more than 7,000 members: motion-imaging executives, creatives, technologists, researchers, and students who volunteer their time and expertise to SMPTE‘s standards development and educational initiatives. A partnership with the Hollywood Professional Association (HPA) connects SMPTE and its membership with the businesses and individuals who support the creation and finishing of media content. Information on joining SMPTE is available at www.smpte.org/join.
