Components
Modern televisions consist of a display, antenna or radio frequency (RF) input (a TV aerial plug or an F connector), and a tuner. The existence of a television tuner (nowadays, a digital television tuner) in a display device distinguishes it from a video monitor—which receives signals that are already processed. Additionally TVs almost always include speakers and teletext. Most modern TVs also feature additional inputs for devices such as DVD players, video game consoles, and headphones; the most common types for analog audio and analog video are RCA (for composite video and component video), mini-DIN for S-Video, SCART and D-terminal can be found in Europe and Japan respectively, the newer HDMI (which can also connect to computers), USB and Bluetooth. Some high-end TVs have Ethernet ports to receive information from the Internet, like stocks, weather, or news. Most TVs made since the early 1980s also feature an infra-red sensor to detect the signals sent by remote controls.

Famous quotes containing the word components:
“Hence, a generative grammar must be a system of rules that can iterate to generate an indefinitely large number of structures. This system of rules can be analyzed into the three major components of a generative grammar: the syntactic, phonological, and semantic components.”
—Noam Chomsky (b. 1928)
