A:Answer Hi, Mickey! When you watch a video on your smartphone or a movie on your computer, the signal is sent over the internet to your home, and then over your wireless network to your smartphone or computer where it is converted to video and audio. This process of delivering media content over the internet is known as streaming. A Roku streaming player is a device you connect to your TV to watch movies, television shows, live sports, news, and more over the internet. You hook it up to your TV just like a cable or satellite set-top box, but unlike those devices, a Roku player does not need a connection from a coaxial cable in the wall, or a satellite dish on your roof. Instead, streaming content is delivered over your home network and the internet from services such as Netflix, The Roku Channel, ESPN, and VUDU.
