The Roku 3 streaming media player works by displaying user-selected audio and video content from the Internet on a television connected to the device. The source options for the streaming content includes free channels, subscription services and online cable channels.
In order to stream content, the Roku 3 must be connected to the Internet, and for high-definition content, Roku recommends a minimum connection speed of 3 megabits per second. Users connect the Roku 3 to the network using a wireless connection or with an Ethernet cable. To display content, the Roku 3 plugs into a television using a high-definition multimedia interface cable.
After the Roku 3 is connected to both the network and a television, users can search for content by title, actor or director with the included remote control, or they can download an app for a smartphone or tablet. The remote control included with the Roku 3 adds voice search capabilities and the option to plug in headphones for private listening. It can also be used as a controller for games and has built-in motion control. Using the app or the built-in USB connector, users can send photos and videos from their phones or tablets through the Roku 3 and display them on televisions.
