Digital Audio Broadcasting
Digital radio is the use of digital technology to transmit or receive across the radio spectrum. Digital transmission by radio waves includes digital broadcasting, and especially digital audio radio services. Types In digital broadcasting systems, the analog audio signal is digital audio, digitized, Audio compression (data), compressed using an audio coding format such as AAC+ (MDCT) or MPEG-1 Audio Layer II, MP2, and transmitted using a digital modulation scheme. The aim is to increase the number of radio programs in a given spectrum, to improve the audio quality, to eliminate fading problems in mobile environments, to allow additional datacasting services, and to decrease the transmission power or the number of transmitters required to cover a region. However, analog radio (AM and FM) is still more popular and listening to radio over IP (Internet Protocol) is growing in popularity. In 2012 four digital wireless radio systems are recognized by the International Telecommunicati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Audience Measurement
Audience measurement measures how many people are in an audience, usually in relation to radio listenership and television viewership, but also in relation to newspaper and magazine readership and, increasingly, web traffic on websites. Sometimes, the term is used as pertaining to practices which help broadcasters and advertisers determine ''who'' is listening rather than just ''how many'' people are listening. In some parts of the world, the resulting relative numbers are referred to as audience share, while in other places the broader term market share is used. This broader meaning is also called audience research. Measurements are broken down by media market, which for the most part corresponds to metropolitan areas, both large and small. Methods Diaries The diary was one of the first methods of recording information. However, this is prone to mistakes and forgetfulness, as well as subjectivity. Data is also collected down to the level of listener opinion of individ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ofcom
The Office of Communications, commonly known as Ofcom, is the government-approved regulatory and competition authority for the broadcasting, telecommunications and postal industries of the United Kingdom. Ofcom has wide-ranging powers across the television, radio, telecoms and postal sectors. It has a statutory duty to represent the interests of citizens and consumers by promoting competition and protecting the public from harmful or offensive material. Some of the main areas Ofcom presides over are licensing, research, codes and policies, complaints, competition and protecting the radio spectrum from abuse (e.g., pirate radio stations). The regulator was initially established by the Office of Communications Act 2002 and received its full authority from the Communications Act 2003. History On , the Queen's Speech to the UK Parliament announced the creation of Ofcom. The new body, which was to replace several existing authorities, was conceived as a "super-regulator" to ov ...

AM Broadcasting
AM broadcasting is radio broadcasting using amplitude modulation (AM) transmissions. It was the first method developed for making audio radio transmissions, and is still used worldwide, primarily for medium wave (also known as "AM band") transmissions, but also on the longwave and shortwave radio bands. The earliest experimental AM transmissions began in the early 1900s. However, widespread AM broadcasting was not established until the 1920s, following the development of vacuum tube receivers and transmitters. AM radio remained the dominant method of broadcasting for the next 30 years, a period called the "Golden Age of Radio", until television broadcasting became widespread in the 1950s and received most of the programming previously carried by radio. Subsequently, AM radio's audiences have also greatly shrunk due to competition from FM (FM broadcasting, frequency modulation) radio, Digital audio broadcasting, Digital Audio Broadcasting (DAB), satellite radio, HD Radio, HD (digi ...

FM Broadcasting
FM broadcasting is a method of radio broadcasting using frequency modulation (FM). Invented in 1933 by American engineer Edwin Armstrong, wide-band FM is used worldwide to provide high fidelity sound over broadcast radio. FM broadcasting is capable of higher fidelity—that is, more accurate reproduction of the original program sound—than other broadcasting technologies, such as AM broadcasting. It is also less susceptible to common forms of interference, reducing static and popping sounds often heard on AM. Therefore, FM is used for most broadcasts of music or general audio (in the audio spectrum). FM radio stations use the very high frequency range of radio frequencies. Broadcast bands Throughout the world, the FM broadcast band falls within the VHF part of the radio spectrum. Usually 87.5 to 108.0 MHz is used, or some portion thereof, with few exceptions: * In the former Soviet republics, and some former Eastern Bloc countries, the older 65.8–74 MHz band ...

DTV Radio
Digital-television radio, DTV radio, or DTR describes the audio channels that are provided with a digital television service. These channels are delivered by cable television, direct-broadcast satellite or digital terrestrial television. In terms of variety, DTR falls somewhere between regular AM and FM radio, and satellite radio. However, because it is delivered through a digital signal, the actual sound quality can exceed both. DTR may be available for free, or as part of a subscription television service. DTR music and audio channels are often provided as part of the "basic" television subscription service or package. In a 2014 study, 11% of Americans listened to DTV radio on an average day, with 5.2% of time spent listening to audio attributed to DTV Radio. Number and availability of channels In the United States, DirecTV offers up to 84 channels of Sonic Tap, and Dish Network offers 95 channels of SiriusXM Satellite Radio and Muzak for residential subscribers, depending o ...
