Understanding SMPTE ST 2110

Internet Protocol (IP) is here!

With the publication of several of SMPTE’s suite of ST 2110 standards, it is more important than ever that you understand how IP can be implemented in your professional media creation facility to ensure interoperability between all ST 2110 compliant equipment.

Virtual Course Description:

This course is intended for engineers and technologists who need to understand the detail in SMPTE’s ST 2110 suite of standards. It assumes a basic understanding of IP and associated terminology. Wes Simpson will guide you in exploring SMPTE ST 2110 and its tremendous potential. He will delve into elements including video, audio, and data encapsulation; identification and synchronization; and traffic shaping.

Upon completion of this course participants should be able to perform the following:

Background and System overview:

  • Describe why the move to IP is important for the broadcast industry
  • Explain how media is transported over IP networks
  • Discuss how the SMPTE ST 2110 standards suite was created
  • Specify the different areas of application for SMPTE ST 2110 and SMPTE ST 2022

Video Encapsulation

  • Explain the advantages of uncompressed video in live TV production and why it is better to transport active video only
  • Describe how a video image is segmented into sample row data for transport in RTP packets 
  • Specify the pgroup size and how many pixels are carried in a pgroup for a specific color sampling
  • Apply your knowledge of SMPTE ST 2110-20 and calculate the size and number of RTP packets for 1 frame of video (e.g. 2160p 60fps)
  • Apply the SMPTE ST 2110-20 packing mode and packet size limits to describe how many pgroups for a specific color sampling can be carried in a packet

Audio Encapsulation

  • Explain how AES67 works and describe its PTP profile
  • Describe the additional constraints on AES67 as per SMPTE ST 2110-30
  • Detail the differences between audio transport for LPCM and AES3 as per SMPTE ST 2110-30 and SMPTE ST 2110-31
  • Specify the receiver conformance level based on channel count, sampling frequency and packet time
  • Apply your knowledge of SMPTE ST 2110-30 to determine the channel grouping symbol and therefore the channel order for a given audio type

Data Encapsulation

  • Explain how a specific ancillary data type is identified and what the identifier structure is.
  • Describe how ANC is packaged into RTP as per SMPTE ST 2110-40
  • Apply your knowledge of SMPTE ST 2110-40 to detail what constraints on ANC in RTP exist

Identification & Synchronization

  • Explain how the PTP synchronization systems work and what PTP profiles exist today.
  • Describe the functions of the different clocks of a device and how they relate to RTP timestamp creation in SMPTE ST 2110
  • Apply the SDP specification in the various parts of SMPTE ST 2110 to signal a specific media essence (e.g. 1080i, 720p, Closed Caption, 5.1 plus stereo audio)
  • Analyze a given SDP text and describe the session properties and identify what media format was signaled

Traffic Shaping

  • Describe the reasons why a timing model for SMPTE ST 2110-10 RTP streams is needed
  • Explain the two SMPTE ST 2110-21 parametric models for the packet delivery timing characteristics  
  • Determine the Packet Read Time for specific Packet Read Schedule and image format
  • Explain the SMPTE ST 2110-21 Virtual Receiver Buffer ModelDescribe the different SMPTE ST 2110-21 compliant sender and receiver types
  • Synthesize the Cmax value for different sender types and image formats based on SMPTE ST 2110-21

Matthew Goldman, Senior Vice President Technology, MediaKind

"Every day it becomes increasingly important that engineers and technologists understand how IP can be implemented in their professional media-creation facilities to ensure interoperability between all ST 2110-compliant equipment. SMPTE ST 2110 documents provide broadcasters, producers, and professional media technology suppliers with the tools that are essential to working int he IP realm, and this SMPTE's virtual course will describe how best to use those tools."


Richard Welsh, CEO of Sundog Media Toolkit

"The "Understanding SMPTE ST 2110" course offers participants the details they need, from the organization that published the standards. It's an excellent opportunity for those who wish to get ahead of the curve in adopting IP-based media technologies and workflows."


Wes Simpson has always been interested in delivering media signals over networks. After starting his career in mobile telephony and then moving into fiber optics, he has focused on high-performance video transport for the past 25 years. He has developed and delivered well-received training seminars covering IP video and media networking technology for a wide range of private clients and SMPTE. Wes is a contributing editor for TV Technology and frequently speaks at events including VidTrans, SMPTE, NAB, and IBC. He has written two books which have both been released as second editions:  “IPTV and Internet Video” and “Video Over IP.” p>

Wes was a founder of the Video Services Forum and was made an Honorary Member.

He is currently the Secretary/Treasurer of the Connecticut Subsection of SMPTE and serves on the SMPTE 32nf subcommittee that created SMPTE ST 2110 as well as on the Board of Editors for SMPTE’s Journal of Motion Imaging. He is also a voting member of the National Academy of Television Arts and Sciences Technology and Engineering Emmy® Awards Committee.

Wes earned a BSEE from Clarkson University and an MBA from the University of Rochester.

The course assumes a basic understanding of IP and associated terminology. The SMPTE Virtual Courses “Introduction to Networks,” “Routing and Switching Essentials,” and the “Essentials of IP Media Transport for Broadcasters: Moving Real-Time Video and Audio over Packet Networks” are not required to register for “Understanding SMPTE ST 2110.” However, these courses enable a deeper understanding of IP, internetworking, and many essential concepts that are referenced in the ST 2110 suite of standards and are recommended prior to enrolling in “Understanding ST 2110.”
