The “Anatomy Of” series is a collection of visuals that give a behind the scenes look at the systems that power over-the-top television.

We’re seeing television’s most significant transformation in decades, with viewers watching more TV on the go and on any device. Streaming viewership has continued to rise and dMVPDs are building new systems and processes to deliver live TV over the internet.

There’s a ton of work that goes on behind the scenes to bring Hulu with Live TV to our viewers. This diagram explores the complex process of receiving content from our network partners and delivering it to our viewers’ devices across the country. Curious to learn more about the process? Be on the lookout for a series of posts detailing our live OTT system, coming in the next few days.
