  • Large Scale Deployment of SMPTE 2110: the IP Live Production Facility
    SMPTE Meeting Presentation Large Scale Deployment of SMPTE 2110: The IP Live Production Facility Steve Sneddon NBCUniversal, [email protected] Chris Swisher NBCUniversal, [email protected] Jeff Mayzurk NBCUniversal, [email protected] Written for presentation at the SMPTE 2019 Annual Technical Conference & Exhibition Abstract. In 2016, NBCUniversal began the project to design and build the new global headquarters for Telemundo Enterprises in Miami Florida. The facility that became known as Telemundo Center would feature 13 production studios and seven control rooms supporting scripted episodic content, daily live news and sports programming, beginning with FIFA World Cup 2018. To support the scale and flexibility required for a facility of this magnitude, the key technical design consideration was the use of a software-defined video network infrastructure. At the time of launch in spring of 2018, Telemundo Center was home to the largest SMPTE ST 2110 environment in the world, consisting of over 12,000 unique HD sources and 150,000 multicast streams across audio and video. This paper will explore the major considerations and challenges in building such a large scale, all-IP broadcast production facility. We will demonstrate design factors around switching of video flows, redundancy, control and orchestration, PTP master clock systems and handoffs to multi-manufacturer SMPTE ST 2110 devices as well as non-IP enabled devices. This paper will also discuss our experience and lessons learned with utilizing a Software
