Satellite televisionSatellite television is a service that delivers television programming to viewers by relaying it from a communications satellite orbiting the Earth directly to the viewer's location. The signals are received via an outdoor parabolic antenna commonly referred to as a satellite dish and a low-noise block downconverter. A satellite receiver decodes the desired television program for viewing on a television set.
Cable televisionCable television is a system for delivering broadcast programming to viewers by radio frequency (RF) signals transmitted through coaxial cable and through fibre-optic cable.
Digital media playerDevice for storage, playback, or viewing of digital media A digital media player in the form of a set-top box, pictured with its remote control A digital media player (also known as a streaming device or streaming box) is a type of consumer electronics device designed for the storage, playback, or viewing of digital media content. They are typically designed to be integrated into a home cinema configuration and attached to a television or AV receiver or both.
Terrestrial televisionTerrestrial television, or over-the-air television (OTA), is a type of television broadcasting in which the content is transmitted via radio waves from the terrestrial (Earth-based) transmitter of a TV station to a TV receiver having an antenna.
Cable converter boxA cable converter box or television converter box is an electronic tuning device that transposes/converts channels from a cable television service to an analog RF signal on a single channel, usually VHF channel 3 or 4, or to a different output for digital televisions such as HDMI. The device allows a television set that is not "cable ready" to receive cable channels.
Television setA television set or television receiver (more commonly called TV, TV set, television, telly, or tele) is an electronic device for viewing and hearing television broadcasts. It combines a tuner, display, and loudspeakers. Introduced in the late 1920s in mechanical form, television sets became a popular consumer product after World War II in electronic form, using cathode ray tube (CRT) technology.
Very high frequencyVery high frequency (VHF) is the ITU designation for the range of radio frequency electromagnetic waves (radio waves) from 30 to 300 megahertz (MHz), with corresponding wavelengths of ten meters to one meter. Frequencies immediately below VHF are denoted high frequency (HF), and the next higher frequencies are known as ultra high frequency (UHF).Internet Protocol televisionTelevision transmitted over a computer network An IPTV set-top box connected to a TV set, designed to receive television from a service called MviewInternet Protocol television (IPTV), also called TV over broadband, is the service delivery of television over Internet Protocol (IP) networks.
Tuner (radio)In electronics and radio, a tuner is a type of receiver subsystem that selects, receives and demodulates radio transmissions, such as AM or FM broadcasts, and converts the received signal into a form suitable for further processing or output, such as to an amplifier or loudspeaker. The verb tuning in radio contexts means adjusting the receiver to detect the desired radio signal carrier frequency that a particular radio station uses.
SignalA signal is both the process and the result of transmission of data over some media accomplished by embedding some variation. Signals are important in multiple subject fields, including signal processing, information theory and biology. In signal processing, a signal is a function that conveys information about a phenomenon. Any quantity that can vary over space or time can be used as a signal to share messages between observers.
Display deviceA display device is an output device for presentation of information in visual or tactile form (the latter used for example in tactile electronic displays for blind people). When the input information that is supplied has an electrical signal the display is called an electronic display. Common applications for electronic visual displays are television sets or computer monitors.
Information applianceAn information appliance (IA) is an appliance that is designed to easily perform a specific electronic function such as playing music, photography, or . Typical examples are smartphones and personal digital assistants (PDAs). Information appliances partially overlap in definition with, or are sometimes referred to as, smart devices, embedded systems, mobile devices or wireless devices. Appliance vs computerThe term information appliance was coined by Jef Raskin around 1979.DongleA dongle is a small piece of computer hardware that connects to a port on another device to provide it with additional functionality, or enable a pass-through to such a device that adds functionality. In computing, the term was initially synonymous with software protection dongles—a form of hardware digital rights management in which a piece of software will only operate if a specified dongle is connected.*As an Amazon Associate I earn from qualifying purchases.
