How Chromecast Works | HowStuffWorks
Chromecast gets things to your TV screen from a remote device in part by using something called the DIAL (Discovery And Launch) protocol. DIAL was developed jointly by Netflix and YouTube, which is owned by Google. DIAL actually launched on Google TV, Google's earlier foray into TV control, and now it's being integrated into devices and apps by a number of manufacturers and content providers.
