Very High Frequency
Very high frequency (VHF) is the ITU designation for the range of radio frequency electromagnetic waves ( radio waves) from 30 to 300 megahertz (MHz), with corresponding wavelengths of ten meters to one meter. Frequencies immediately below VHF are denoted high frequency (HF), and the next higher frequencies are known as ultra high frequency (UHF). VHF radio waves propagate mainly by line-of-sight, so they are blocked by hills and mountains, although due to refraction they can travel somewhat beyond the visual horizon out to about 160 km (100 miles). Common uses for radio waves in the VHF band are Digital Audio Broadcasting (DAB) and FM radio broadcasting, television broadcasting, two-way land mobile radio systems (emergency, business, private use and military), long range data communication up to several tens of kilometers with radio modems, amateur radio, and marine communications. Air traffic control communications and air navigation systems (e.g. VOR and ILS) wo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Virtual Channel
In most telecommunications organizations, a virtual channel is a method of remapping the ''program number'' as used in H.222 Program Association Tables and Program Mapping Tables to a channel number that can be entered via digits on a receiver's remote control. Often, "virtual channels" are implemented in digital television, helping users to find a desired channel easily, or easing the transition from analogue to digital broadcasting in general. The practice of assigning virtual channels is most common in those parts of the world where TV stations were colloquially named after the RF channel they were transmitting on ("Channel 6 Springfield"), as it was common in North America during the analogue TV era. In other parts of the world, such as Europe, virtual channels are rarely used or needed, as TV stations there identify themselves by name, not by RF channel or callsign. A "virtual channel" was first used for DigiCipher 2 in North America. It was later used and referred to as a l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Retro TV
Retro TV (stylized as retrotv), formerly known as Retro Television Network, is an American broadcast television network owned by Get After It Media. The network mainly airs classic television sitcoms and drama series from the 1950s through the 1980s, although it also includes more recent programs from the 1990s and 2000s. Through its ownership by Luken, Retro TV is a sister network to several broadcast network properties that are wholly or jointly owned by the company, including the family-oriented Family Channel and country music-oriented network Heartland. At its outset, Retro TV was designed to be broadcast on the digital subchannels of television stations; however in recent years, the network's affiliate body has been drawn down to primarily low-power stations, as many station groups have replaced the network on the subchannels of their full-power major network affiliates with similarly formatted networks such as Antenna TV and MeTV, which have assumed rights to many of ...

Flash-cut
A flash cut, also called a flash cutover, is an immediate change in a complex system, with no phase-in period. In the United States, some telephone area codes were split or overlaid immediately, rather than being phased in with a permissive dialing period. An example is telephone area code 213, which serves downtown Los Angeles and its immediate environs, split in January 1951 into 213 and 714 all at once. Another example is an immediate switch from an analog television channel to a digital television channel on the same frequency, where the two cannot operate in parallel without interference. A flash cut can also define a procedure in which multiple components of computer infrastructure are upgraded in multiple ways, all at once, with no phase-in period. In film, an extremely brief shot, sometimes as short as one frame, which is nearly subliminal in effect. Also a series of short staccato shots that create a rhythmic effect.

Palmdale, California
Palmdale is a city in northern Los Angeles County in the U.S. state of California. The city lies in the Antelope Valley region of Southern California. The San Gabriel Mountains separate Palmdale from the Los Angeles Basin to the south. On August 24, 1962, Palmdale became the first city in the Antelope Valley. Forty-seven years later, in November 2009, voters approved making it a charter city. Palmdale's population was 169,450 at the 2020 census, up from 152,750 at the 2010 census. Palmdale is the 32nd most populous city in California. Together with its immediate northern neighbor, the city of Lancaster, the Palmdale/Lancaster urban area had an estimated population of 513,547 as of 2013. History Palmdale was first inhabited by Native Americans. Populated by different cultures for an estimated 11,000 years, the Antelope Valley was a trade route for Native Americans traveling from Arizona and New Mexico to California's coast.

Indian Wells Valley, California
Indian Wells Valley is an arid north-south basin in east-central California. In the geologic sense, it is a southern extension of Owens Valley to the north, with the recent volcanics of the Coso Range being the separator. It is defined by a major fault on the west side of the valley. Unlike Owens Valley, it is bound by a fault to the south, the Garlock Fault (within the El Paso Mountains). This valley is part of the northwesternmost Mojave Desert plant community and ecoregion. The largest city in the valley is Ridgecrest. Other locations include Inyokern, Indian Wells, and communities associated with the China Lake Naval Weapons Center, the primary industry in the valley. California State Route 14 and US Highway 395 are the main transportation corridors through the valley.

Terrestrial Television
Terrestrial television or over-the-air television (OTA) is a type of television broadcasting in which the signal transmission occurs via radio waves from the terrestrial (Earth-based) transmitter of a TV station to a TV receiver having an antenna. The term ''terrestrial'' is more common in Europe and Latin America, while in Canada and the United States it is called ''over-the-air'' or simply ''broadcast''. This type of TV broadcast is distinguished from newer technologies, such as satellite television (direct broadcast satellite or DBS television), in which the signal is transmitted to the receiver from an overhead satellite; cable television, in which the signal is carried to the receiver through a cable; and Internet Protocol television, in which the signal is received over an Internet stream or on a network utilizing the Internet Protocol. Terrestrial television stations broadcast on television channels with frequencies between about 52 and 600 MHz in the VHF and U ...

Mount Wilson (California)
Mount Wilson is a peak in the San Gabriel Mountains, located within the San Gabriel Mountains National Monument and Angeles National Forest in Los Angeles County, California. With only minor topographical prominence the peak is not naturally noticeable from a distance, although it is easily identifiable due to the large number of antennas near its summit. It is a subsidiary peak of nearby San Gabriel Peak. It is the location of the Mount Wilson Observatory, which is an important astronomical facility in Southern California with historic and telescopes, and and solar towers. The newer CHARA Array, run by Georgia State University, is also sited there and does important interferometric stellar research. The summit is at . While not the tallest peak in its vicinity, it is high enough in elevation that snow can sometimes interrupt astronomical activities on the mountain. All of the mountains south of the summit are far shorter leading to unobstructed views across the Los An ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Broadcast Transmitter
A broadcast transmitter is an electronic device which radiates radio waves modulated with information content intended to be received by the general public. Examples are a radio broadcasting transmitter which transmits audio (sound) to broadcast radio receivers (radios) owned by the public, or a television transmitter, which transmits moving images (video) to television receivers (televisions). The term often includes the antenna which radiates the radio waves, and the building and facilities associated with the transmitter. A broadcasting station (radio station or television station) consists of a broadcast transmitter along with the production studio which originates the broadcasts. Broadcast transmitters must be licensed by governments, and are restricted to specific frequencies and power levels. Each transmitter is assigned a unique identifier consisting of a string of letters and numbers called a callsign, which must be used in all broadcasts. Exciter In broadcastin ...

City Of License
In American, Canadian, and Mexican broadcasting, a city of license or community of license is the community that a radio station or television station is officially licensed to serve by that country's broadcast regulator. In North American broadcast law, the concept of ''community of license'' dates to the early days of AM radio broadcasting. The requirement that a broadcasting station operate a ''main studio'' within a prescribed distance of the community which the station is licensed to serve appears in United States federal law, U.S. law as early as 1939. Various specific obligations have been applied to broadcasters by governments to fulfill public policy objectives of broadcast localism (politics), localism, both in radio and later also in television, based on the legislative presumption that a broadcaster fills a similar role to that held by community newspaper publishers.

Television Station
A television station is a set of equipment managed by a business, organisation or other entity, such as an amateur television (ATV) operator, that transmits video content and audio content via radio waves directly from a transmitter on the earth's surface to any number of tuned receivers simultaneously. Overview Most often the term "television station" refers to a station which broadcasts structured content to an audience or it refers to the organization that operates the station. A terrestrial television transmission can occur via analog television signals or, more recently, via digital television signals. Television stations are differentiated from cable television or other video providers in that their content is broadcast via terrestrial radio waves. A group of television stations with common ownership or affiliation are known as a TV network and an individual station within the network is referred to as O&O or affiliate, respectively. Because television station signals u ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Network Affiliate
In the broadcasting industry (particularly in North America, and even more in the United States), a network affiliate or affiliated station is a local broadcaster, owned by a company other than the owner of the network, which carries some or all of the lineup of television programs or radio programs of a television or radio network. This distinguishes such a television or radio station from an owned-and-operated station (O&O), which is owned by the parent network. Notwithstanding this distinction, it is common in informal speech (even for networks or O&Os themselves) to refer to any station, O&O or otherwise, that carries a particular network's programming as an affiliate, or to refer to the status of carrying such programming in a given market as an "affiliation". Overview Stations which carry a network's programming by method of affiliation maintain a contractual agreement, which may allow the network to dictate certain requirements that a station must agree to as par ...
