Radom Longwave Transmitter
Radom longwave transmitter is a facility for commercial longwave transmission ( not broadcasting) west of Radom in Poland. Radom longwave transmitter, situated at 51°25'N and 21°07' E is the only transmission facility for frequencies under 100 kHz in Poland. It uses an antenna system carried by 1 150 metre and 3 100 metre tall guyed masts. Radom longwave transmitter worked ( and perhaps still works) on the following frequencies with the following callsigns: * 55.75 kHz, callsign: SOA60, 40 kW transmission power * 58.25 kHz, callsign: SOA70, 360 kW transmission power * 62.45 kHz, callsign: SOA80, 40 kW transmission power * 64.9 kHz, callsign: SOA90, 40 kW transmission power * 76.35 kHz, callsign: SNA20, 40 kW transmission power * 80.5 kHz, callsign: SNA30, 40 kW transmission power * 81.35 kHz, callsign: SNA40, 40 kW transmission power Today's use Today one of the masts is used for FM- and TV-broadcasting ...

Radom
Radom is a city in east-central Poland, located approximately south of the capital, Warsaw. It is situated on the Mleczna River in the Masovian Voivodeship (since 1999), having previously been the seat of a separate Radom Voivodeship (1975–1998). Radom is the fourteenth-largest city in Poland and the second-largest in its province with a population of 206,946 as of 2021. For centuries, Radom was part of the Sandomierz Province of the Kingdom of Poland and the later Polish–Lithuanian Commonwealth. Despite being part of the Masovian Voivodeship, the city historically belongs to Lesser Poland. It was a significant center of administration, having served as seat of the Crown Council which ratified the Pact of Vilnius and Radom between Lithuania and Poland in 1401. The Nihil novi and Łaski's Statute were adopted by the Sejm at Radom's Royal Castle in 1505. In 1976, it was a center of the June 1976 protests. The city is home to the biennial Radom Air Show, the largest air sho ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
DVB-T
DVB-T, short for Digital Video Broadcasting – Terrestrial, is the DVB European-based consortium standard for the broadcast transmission of digital terrestrial television that was first published in 1997 and first broadcast in Singapore in February, 1998. This system transmits compressed digital audio, digital video and other data in an MPEG transport stream, using coded orthogonal frequency-division multiplexing (COFDM or OFDM) modulation. It is also the format widely used worldwide (including North America) for Electronic News Gathering for transmission of video and audio from a mobile newsgathering vehicle to a central receive point. It is also used in the US by Amateur television operators. Basics Rather than carrying one data carrier on a single radio frequency (RF) channel, COFDM works by splitting the digital data stream into a large number of slower digital streams, each of which digitally modulates a set of closely spaced adjacent sub-carrier frequencies. In the cas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
MPEG-4
MPEG-4 is a group of international standards for the compression of digital audio and visual data, multimedia systems, and file storage formats. It was originally introduced in late 1998 as a group of audio and video coding formats and related technology agreed upon by the ISO/IEC Moving Picture Experts Group (MPEG) ( ISO/IEC JTC 1/SC29/WG11) under the formal standard ISO/IEC 14496 – ''Coding of audio-visual objects''. Uses of MPEG-4 include compression of audiovisual data for Internet video and CD distribution, voice (telephone, videophone) and broadcast television applications. The MPEG-4 standard was developed by a group led by Touradj Ebrahimi (later the JPEG president) and Fernando Pereira. Background MPEG-4 absorbs many of the features of MPEG-1 and MPEG-2 and other related standards, adding new features such as (extended) VRML support for 3D rendering, object-oriented composite files (including audio, video and VRML objects), support for externally specified Digital ...

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. The availability of various types of archival st ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Radio
Radio is the technology of signaling and communicating using radio waves. Radio waves are electromagnetic waves of frequency between 30 hertz (Hz) and 300 gigahertz (GHz). They are generated by an electronic device called a transmitter connected to an antenna which radiates the waves, and received by another antenna connected to a radio receiver. Radio is very widely used in modern technology, in radio communication, 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 objects like aircraft, ships, spacecraf ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
