A meeting in association with the Society of Broadcast Engineers, Chapter 11, Southern New England...
With Karl Kuhn, Senior Video Applications Engineer, Tektronix

This presentation by Karl Kuhn, Senior Video Applications Engineer at Tektronix, will be a tutorial on what you need to know to understand the challenges we face in the process of making the transition to IP based transport for video, audio and data. This move toward infrastructure efficiency has brought new technical complexity requiring broadcast engineers to gain an understanding of the technology and the new techniques needed to monitor these signals. The development of SMPTE ST 2110 is a suite of standards that provide encapsulation of uncompressed video within IP packets and for live IP production carrying separate streams of video, audio and data packets. This new standard also allows for SMPTE ST 2022-6 that provides encapsulation of uncompressed SDI as well as ST 2059 for system timing, replacing genlock.

In this session, Karl will take a look at the basic structure of the packets for ST 2022 and ST 2110, how variable delay across the network introduces jitter at the receiver, and how measurements can be made on the stream. Latency in the network can produce out of order packets or corruption of the data causing packets to be dropped. Therefore it is important to monitor the stream to ensure an error free network to ensure transmission of High Bit Rate Media and see how these errors affect the actual video and audio signal.

Karl launched his career at Tektronix in 2000. Prior to Tektronix he was the lead Video Test Engineer for IBM in their Digital Video Development Laboratory in Bethesda, MD. Karl holds 3 U.S. patents and 1 Japanese patent that cover In-service testing of digital broadcast video. He is a contributing author for the 11th Edition of the NAB Handbook responsible for chapter 2.9 covering digital video standards and practices. He is the past SMPTE Eastern Region Governor and now SMPTE North American Sections Director. In 2015 Karl was raised to SMPTE Fellow. He is also a Certified Project Management Professional thru PMI and the George Washington University.
