Remote Pickup Unit
A remote pickup unit or RPU is a radio system using special radio frequencies set aside for electronic news-gathering (ENG) and remote broadcasting. It can also be used for other types of point-to-point radio links. An RPU is used to send program material from a remote location to the broadcast station or network. Usually these systems use specialized high audio fidelity radio equipment. One manufacturer, Marti, was best known for manufacturing remote pickup equipment, so much so that the name is usually used to refer to a remote pickup unit regardless of who the actual equipment manufacturer actually is.{{cite news , title=This Pot Reserved for Marti Remote , first=Charles , last=Fitch , publisher=Radio World , date=2005-05-25 Today much of the remote broadcast use digital audio system fed over ISDN telephone lines.

Radio
Radio is the technology of communicating using radio waves. Radio waves are electromagnetic waves of frequency between 3 hertz (Hz) and 300 gigahertz (GHz). They are generated by an electronic device called a transmitter connected to an antenna which radiates the waves. They can be received by other antennas connected to a radio receiver; this is the fundamental principle of radio communication. In addition to communication, radio is used for radar, radio navigation, remote control, remote sensing, and other applications. In radio communication, used in radio and television broadcasting, cell phones, two-way radios, wireless networking, and satellite communication, among numerous other uses, radio waves are used to carry information across space from a transmitter to a receiver, by modulating the radio signal (impressing an information signal on the radio wave by varying some aspect of the wave) in the transmitter. In radar, used to locate and track ob ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Radio Frequencies
Radio frequency (RF) is the oscillation rate of an alternating electric current or voltage or of a magnetic, electric or electromagnetic field or mechanical system in the frequency range from around to around . This is roughly between the upper limit of audio frequencies that humans can hear (though these are not electromagnetic) and the lower limit of infrared frequencies, and also encompasses the microwave range. These are the frequencies at which energy from an oscillating current can radiate off a conductor into space as radio waves, so they are used in radio technology, among other uses. Different sources specify different upper and lower bounds for the frequency range. Electric current Electric currents that oscillate at radio frequencies (RF currents) have special properties not shared by direct current or lower audio frequency alternating current, such as the 50 or 60 Hz current used in electrical power distribution. * Energy from RF currents in conductors can ...

Electronic News-gathering
Electronic news gathering (ENG) or electronic journalism (EJ) is usage of electronics, electronic video and sound recording and reproduction, audio technologies by journalist, reporters to gather and present news instead of using film cameras. The term was coined during the rise of videotape technology in the 1970s. ENG can involve anything from a single reporter with a single professional video camera, to an entire television crew taking a truck on location. Beginnings Shortcomings of film The term ENG was created as television news departments moved from film-based news gathering to electronic field production technology in the 1970s. Since film requires chemical processing before it can be viewed and edited, it generally took at least an hour from the time the film arrived back at the television station or network news department until it was ready to be broadcast. Film editing was done by hand on what was known as "Complementary colors, color reversal" film, usually Eas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Remote Broadcast
In broadcast engineering, a remote broadcast (usually just called a remote or a live remote, or in news parlance, a live shot) is broadcasting done from a location away from a formal television or radio studio and is considered an electronic field production (EFP). A remote pickup unit (RPU) is usually used to transmit the audio and/or video back to the broadcast station, where it joins the normal airchain. Other methods include satellite trucks, production trucks and even regular telephone lines if necessary. History The first airing of a remote broadcast came in 1924, when Loew's Theater publicist and WHN (New York City) station manager Nils Granlund leased telegraph lines from Western Union to provide the first link in what became called cabaret broadcasting." By early 1925, Granlund had established remote lines between WHN and more than thirty New York City jazz nightclubs, including the Silver Slipper, The Parody Club, the Cotton Club, the Strand Roof, and Club Mori ...

Broadcast Network
A terrestrial network (or broadcast network in the United States) is a group of radio stations, television stations, or other electronic media outlets, that form an agreement to air, or broadcast, content from a centralized source. For example, , and (United States, U.S.), (Canada), the BBC (United Kingdom, UK), the (Australia), ARD (broadcaster), ARD (Germany), (Philippines), (South Korea), and NHK (Japan) are TV networks that provide television program, programming for local terrestrial television network affiliate, station affiliates to air using signals that can be picked up by the home television sets of local viewers. Networks generally, but not always, operate on a national scale; that is, they cover an entire country. Streaming media, Internet radio, and webcasting are sometimes considered forms of broadcasting despite the lack of terrestrial stations; its practitioners may also be called "broadcasters" or even "broadcast networks". American networks AT&T's "WEA ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
MARTI Electronics
Marti Electronics, a division of BE, manufactures RF Remote Pick-Up equipment for the broadcast industry. Marti has been supplying such hardware since 1960 with few competitors in its very vertical market. Because this equipment was so ubiquitous for so many years, the words "Marti" and "RPU" have become almost synonymous among broadcast engineers. Marti is headquartered in Quincy, Illinois.

ISDN
Integrated Services Digital Network (ISDN) is a set of communication standards for simultaneous digital transmission of voice, video, data, and other network services over the digitalised circuits of the public switched telephone network. Work on the standard began in 1980 at Bell Labs and was formally standardized in 1988 in the CCITT "Red Book". By the time the standard was released, newer networking systems with much greater speeds were available, and ISDN saw relatively little uptake in the wider market. One estimate suggests ISDN use peaked at a worldwide total of 25 million subscribers at a time when 1.3 billion analog lines were in use. ISDN has largely been replaced with digital subscriber line (DSL) systems of much higher performance. Prior to ISDN, the telephone system consisted of digital links like T1/ E1 on the long-distance lines between telephone company offices and analog signals on copper telephone wires to the customers, the " last mile". At the time, t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Telephone
A telephone, colloquially referred to as a phone, is a telecommunications device that enables two or more users to conduct a conversation when they are too far apart to be easily heard directly. A telephone converts sound, typically and most efficiently the human voice, into electronic signals that are transmitted via Electrical cable, cables and other communication channels to another telephone which reproduces the sound to the receiving user. The term is derived from and (, ''voice''), together meaning ''distant voice''. In 1876, Alexander Graham Bell was the first to be granted a United States patent for a device that produced clearly intelligible replication of the human voice at a second device. This instrument was further developed by many others, and became rapidly indispensable in business, government, and in households. The essential elements of a telephone are a microphone (''transmitter'') to speak into and an earphone (''receiver'') which reproduces the voice a ...
