Test cardA test card, also known as a test pattern or start-up/closedown test, is a television test signal, typically broadcast at times when the transmitter is active but no program is being broadcast (often at sign-on and sign-off), and may be accompanied by a bleep sound. Used since the earliest TV broadcasts, test cards were originally physical cards at which a television camera was pointed, allowing for simple adjustments of picture quality.
Call signIn broadcasting and radio communications, a call sign (also known as a call name or call letters—and historically as a call signal—or abbreviated as a call) is a unique identifier for a transmitter station. A call sign can be formally assigned by a government agency, informally adopted by individuals or organizations, or even cryptographicallyencoded to disguise a station's identity.
Station identificationStation identification (ident, network ID, channel ID or bumper) is the practice of radio and television stations and networks identifying themselves on-air, typically by means of a call sign or brand name (sometimes known, particularly in the United States, as a "sounder", "stinger" or "sting", more generally as a station or network ID). This may be to satisfy requirements of licensing authorities, a form of branding, or a combination of both.News BroadcastingNews UK Broadcasting Limited, trading as News Broadcasting (formerly Wireless Group Limited and UTV Media plc), is a radio and digital broadcasting network with headquarters in Belfast, Northern Ireland. It currently operates five stations in Ireland and 18 in the United Kingdom. The company was formerly known as UTV Media, owned by UTV Television.
Public broadcastingElectronic media outlets whose primary mission is public servicePublic broadcasting (or public service broadcasting) is radio, television, and other electronic media whose primary mission is public service with a commitment to avoiding political and commercial influence. Public broadcasters receive funding from public financing, license fees, individual contributions and donations, commercial advertising and corporate underwriting.
TransmitterIn electronics and telecommunications, a radio transmitter or just transmitter (often abbreviated as XMTR or TX in technical documents) is an electronic device which produces radio waves with an antenna with the purpose of signal transmission to a radio receiver. The transmitter itself generates a radio frequencyalternating current, which is applied to the antenna. When excited by this alternating current, the antenna radiates radio waves.
HertzThe hertz (symbol: Hz) is the unit of frequency in the International System of Units (SI), often described as being equivalent to one event (or cycle) per second. The hertz is an SI derived unit whose formal expression in terms of SI base units is 1/s or s−1, meaning that one hertz is one per second or the reciprocal of one second. It is used only in the case of periodic events.Broadcast automationBroadcast automation incorporates the use of broadcast programming technology to automate broadcasting operations. Used either at a broadcast network, radio station or a television station, it can run a facility in the absence of a human operator. It can also run in a live assist mode when there are on-air personnel present at the master control, television studio or control room.Automatic transmission systemAn automatic transmission system (ATS) is an automated system designed to keep a broadcast radio or television station's transmitter and antenna system running without direct human oversight or attention for long periods. Such systems are occasionally referred to as automated transmission systems to avoid confusion with the automatic transmission of an automobile.
Remote controlA remote control, also known colloquially as a remote or clicker, is an electronic device used to operate another device from a distance, usually wirelessly. In consumer electronics, a remote control can be used to operate devices such as a television set, DVD player or other digital home media appliance. A remote control can allow operation of devices that are out of convenient reach for direct operation of controls. They function best when used from a short distance.
24/7 serviceIn commerce and industry, 24/7 or 24-7 service (usually pronounced "twenty-four seven") is service that is available at any time of day, 24 hours, and every day of the week, 7 days. An alternate orthography is 24×7 (usually pronounced "twenty-four by seven"). Less commonly used are the terms 24/7/52 (adding "52 weeks") and 24/7/365 (adding "365 days") make it clear that service is available every day of the year including the one extra day on leap years.
DTMF signalingDual-tone multi-frequency (DTMF) signaling is a telecommunication signaling system using the voice-frequency band over telephone lines between telephone equipment and other communications devices and switching centers. DTMF was first developed in the Bell System in the United States, and became known under the trademark Touch-Tone for use in push-button telephones, starting in 1963. The DTMF frequencies are standardized in ITU-TRecommendation Q.23.
