If they can hold on for “breakfast” long enough, the on-site commissary is known to serve tasty omelets after midnight.

On an ordinary day, when the Olympics are not happening, about 750 people work out of the facility, a gleaming 300,000-square-foot structure that formerly was a Clairol factory. NBC Sports took it over in 2012. The facility was designed specifically to handle the load of an Olympics, and during the Games the number of workers swells to about 1,300, in addition to the 2,000 NBC staff members in South Korea.

The Stamford crew passes the hours monitoring dozens of video and audio feeds that zip across the Pacific Ocean from South Korea on one of four fiber-optic lines before spider-webbing their way across the United States. The journey takes just milliseconds.

The broadcast operations center also receives satellite feeds from South Korea, a fail-safe to ensure the Games stay on-air no matter what happens. These feeds take a comparatively sluggish two seconds to reach Stamford. “It’s a speed-of-light problem,” said Tim Canary, the vice president of engineering.

As it has for past Olympics, NBC is calling much of the action stateside in an effort to save money. This takes place in Studio 4, usually used for storage but now filled with eight portable black booths, each about the size of a small bedroom. On one side of each occupied booth are two producers; on the other are two announcers calling an event “live” while watching monitors.

Last Thursday, the 2006 bronze medalist Pete Fenson, a curling analyst, was commentating on a match from one of the booths. Events can even be called by announcers in both South Korea and Stamford, through a process called “collaborative off-tube.”
