National Radio Systems Committee
The National Radio Systems Committee (NRSC) is an organization sponsored by the Consumer Technology Association (CTA) and the National Association of Broadcasters (NAB). Its main purpose is to set industry technical standards for radio broadcasting in the United States. While regulatory authority rests with the FCC, it usually adopts NRSC recommendations, such as RBDS and spectral masks. For U.S. television, the NTSC sets standards. Standards *NRSC-1: AM Preemphasis/Deemphasis and Broadcast Audio Transmission Bandwidth; see AMAX *NRSC-2: Emission Limitation for Analog AM Broadcast Transmission; see Spectral mask *NRSC-4: United States Radio Broadcast Data System Radio Data System (RDS) is a communications protocol standard for embedding small amounts of digital information in conventional FM broadcasting, FM radio broadcasts.

Organization
An organization or organisation (English in the Commonwealth of Nations, Commonwealth English; American and British English spelling differences#-ise, -ize (-isation, -ization), see spelling differences), is an legal entity, entity—such as a company, an institution, or an Voluntary association, association—comprising one or more person, people and having a particular purpose. The word is derived from the Greek word ''organon'', which means tool or instrument, musical instrument, and Organ (anatomy), organ. Types There are a variety of legal types of organizations, including corporations, governments, non-governmental organizations, political organizations, international organizations, armed forces, charitable organization, charities, not-for-profit corporations, partnerships, cooperatives, and Types of educational institutions, educational institutions, etc. A hybrid organization is a body that operates in both the public sector and the private sector simultaneously, fu ...

USFCC
The Federal Communications Commission (FCC) is an independent agency of the United States federal government that regulates communications by radio, television, wire, satellite, and cable across the United States. The FCC maintains jurisdiction over the areas of broadband access, fair competition, radio frequency use, media responsibility, public safety, and homeland security. The FCC was formed by the Communications Act of 1934 to replace the radio regulation functions of the Federal Radio Commission. The FCC took over wire communication regulation from the Interstate Commerce Commission. The FCC's mandated jurisdiction covers the 50 states, the District of Columbia, and the territories of the United States. The FCC also provides varied degrees of cooperation, oversight, and leadership for similar communications bodies in other countries of North America. The FCC is funded entirely by regulatory fees. It has an estimated fiscal-2022 budget of US $388 million. It has 1,482 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
HD Radio
HD Radio (HDR) is a trademark for an in-band on-channel (IBOC) digital radio broadcast technology. It generally simulcasts an existing analog radio station in digital format with less noise and with additional text information. HD Radio is used primarily by AM and FM radio stations in the United States, Canada, and Mexico, with a few implementations outside North America. The term "on channel" is a misnomer because the system actually broadcasts on the ordinarily unused channels adjacent to an existing radio station's allocation. This leaves the original analog signal intact, allowing enabled receivers to switch between digital and analog as required. In most FM implementations, from 96 to 128 kbps of capacity is available. High-fidelity audio requires only 48 kbps so there is ample capacity for additional channels, which HD Radio refers to as "multicasting". HD Radio is licensed so that the simulcast of the main channel is royalty-free. The company makes its money ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Radio Broadcast Data System
Radio Data System (RDS) is a communications protocol standard for embedding small amounts of digital information in conventional FM radio broadcasts. RDS standardizes several types of information transmitted, including time, station identification and program information. The standard began as a project of the European Broadcasting Union (EBU), but has since become an international standard of the International Electrotechnical Commission (IEC). Radio Broadcast Data System (RBDS) is the official name used for the U.S. version of RDS. The two standards are only slightly different, with receivers able to work with either system and only minor inconsistencies in the displayed data. Both versions carry data at 1,187.5 bits per second on a 57 kHz subcarrier, so there are exactly 48 cycles of subcarrier during every data bit. The RBDS/RDS subcarrier was set to the third harmonic of the 19 kHz FM stereo pilot tone to minimize interference and intermodulation between the d ...

Spectral Mask
{{unreferenced, date=February 2008 In telecommunications, a spectral mask, also known as a channel mask or transmission mask, is a mathematically-defined set of lines applied to the levels of radio (or optical) transmissions. The spectral mask is generally intended to reduce adjacent-channel interference by limiting excessive radiation at frequencies beyond the necessary bandwidth. Attenuation of these spurious emissions is usually done with a band-pass filter, tuned to allow through the correct center frequency of the carrier wave, as well as all necessary sidebands. The spectral mask is usually one of the things defined in a bandplan for each particular band. It is essential in assuring that a transmission stays within its channel. An FM radio station, for example, must attenuate everything beyond ±75 kHz from the center frequency by a few decibels, and anything beyond ±100 kHz (the channel boundary) by much more. Emissions on further adjacent channels must be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
AMAX
AMAX is a certification program for AM radio broadcasting standards, created in the United States beginning in 1991 by the Electronic Industries Association (EIA) and the National Association of Broadcasters (NAB). It was developed with the intention of helping AM stations, especially ones with musical formats, become more competitive with FM broadcasters. The standards cover both consumer radio receivers and broadcasting station transmission chains. Although the Federal Communications Commission (FCC) endorsed the AMAX proposal, the agency never made it into a formal requirement, leaving its adoption as voluntary. Ultimately few receiver manufacturers and radio stations adhered to the standard, thus it has done little to stem the continued decline in AM station listenership. Standards Receiver AMAX radio receivers are divided into three categories: home, automotive and portable. Receiver certification requirements include: * Wide audio bandwidth, with a minimum of 7,500 her ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
NTSC
The first American standard for analog television broadcast was developed by National Television System Committee (NTSC)National Television System Committee (1951–1953), Report and Reports of Panel No. 11, 11-A, 12–19, with Some supplementary references cited in the Reports, and the Petition for adoption of transmission standards for color television before the Federal Communications Commission, n.p., 1953], 17 v. illus., diagrs., tables. 28 cm. LC Control No.:5402138Library of Congress Online Catalog/ref> in 1941. In 1961, it was assigned the designation CCIR System M, System M. In 1953, a second NTSC standard was adopted, which allowed for color television broadcast compatible with the existing stock of black-and-white receivers. It is one of three major color formats for analog television, the others being PAL and SECAM. NTSC color is usually associated with the System M. The only other broadcast television system to use NTSC color was the System J. Since the intro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Television
Television, sometimes shortened to TV, is a telecommunication medium for transmitting moving images and sound. The term can refer to a television set, or the medium of television transmission. Television is a mass medium for advertising, entertainment, news, and sports. Television became available in crude experimental forms in the late 1920s, but only after several years of further development was the new technology marketed to consumers. After World War II, an improved form of black-and-white television broadcasting became popular in the United Kingdom and the United States, and television sets became commonplace in homes, businesses, and institutions. During the 1950s, television was the primary medium for influencing public opinion.Diggs-Brown, Barbara (2011''Strategic Public Relations: Audience Focused Practice''p. 48 In the mid-1960s, color broadcasting was introduced in the U.S. and most other developed countries.

Authority
In the fields of sociology and political science, authority is the legitimate power of a person or group over other people. In a civil state, ''authority'' is practiced in ways such a judicial branch or an executive branch of government.''The New Fontana Dictionary of Modern Thought'' Third Edition, Allan Bullock and Stephen Trombley, Eds. p. 115. In the exercise of governance, the terms ''authority'' and ''power'' are inaccurate synonyms. The term ''authority'' identifies the political legitimacy, which grants and justifies the ruler's right to exercise the power of government; and the term ''power'' identifies the ability to accomplish an authorized goal, either by compliance or by obedience; hence, ''authority'' is the ''power'' to make decisions and the legitimacy to make such legal decisions and order their execution. History Ancient understandings of authority trace back to Rome and draw later from Catholic ( Thomistic) thought and other traditional understanding ...

Sponsor (commercial)
Sponsoring something (or someone) is the act of supporting an event, activity, person, or organization financially or through the provision of products or services. The individual or group that provides the support, similar to a benefactor, is known as the sponsor. Definition Sponsorship is a cash and/or in-kind fee paid to a property (typically in sports, arts, entertainment or causes) in return for access to the exploitable commercial potential associated with that property. While the sponsoree (property being sponsored) may be nonprofit, unlike philanthropy, sponsorship is done with the expectation of a commercial return. While sponsorship can deliver increased awareness, brand building and propensity to purchase, it is different from advertising. Unlike advertising, sponsorship can not communicate specific product attributes. Nor can it stand alone, as sponsorship requires support elements. Theories A range of psychological and communications theories have been used to exp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
