What functions can Chromecast stream to your TV?

Chromecast accepts things to your TV screen from a piece of remote equipment in the machine by utilizing something called the DIAL (Discovery and Launch) protocol. DIAL was formed together by Netflix and YouTube, which is owned by Google. DIAL truly launched on Google TV, Google’s pioneering incursion within TV control, and now it’s being blended into devices and apps by plenty of manufacturers and content providers.

One of Chromecast’s components, the DIAL Service Discovery protocol has Manageable Service Discovery Protocol variant 1.1, which is characterized by UPnP (Universal Plug and Play), to concede a DIAL client device to discover a DIAL server equipment operating on the same interface. The other component, the DIAL REST (Representational State Transfer) Service, is then reached to a query, launch or stop applications using HTTP (Hypertext Transfer Protocol) applications from the client device to the server device. In this case of Chromecast, your phone, tablet or computer is the client and the Chromecast itself is the server.
