Bradley University
Bradley University is a private university in Peoria, Illinois. Founded in 1897, Bradley University enrolls 5,400 students who are pursuing degrees in more than 100 undergraduate programs and more than 30 graduate programs in five colleges. The university is accredited by the Higher Learning Commission and 22 specialized and professional accreditors. History The Bradley Polytechnic Institute was founded by philanthropist Lydia Moss Bradley in 1897 in memory of her husband Tobias and their six children, all of whom died before Bradley, leaving her a childless widow. The Bradleys had discussed establishing an orphanage in memory of their deceased children. After some study and travel to various institutions, Mrs. Bradley decided instead to found a school where young people could learn how to do practical things to prepare them for living in the modern world. As a first step toward her goal, in 1892 she purchased a controlling interest in Parsons Horological School in LaPorte, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
WTVP
WTVP (channel 47) is a PBS member television station in Peoria, Illinois, United States, owned by the Illinois Valley Public Telecommunications Corporation. The station's studios are located on State Street in downtown Peoria, and its transmitter is located along Interstate 474 in East Peoria. Serving as the Peoria area's public television station since 1971, WTVP broadcasts PBS and local programming. Originally housed on studios at the campus of Bradley University but separately owned, WTVP moved to its present facility in 2003. However, borrowing costs from construction and insufficient pledge revenues led to a near-foreclosure and shutdown of the station in January 2008 by its lender. Sufficient support from the community allowed WTVP to settle its debts and remain on the air. History Early years Illinois Valley Public Telecommunications Corporation applied to the Federal Communications Commission (FCC) on March 10, 1970, for permission to build an educational television statio ...

Effective Radiated Power
Effective radiated power (ERP), synonymous with equivalent radiated power, is an IEEE standardized definition of directional radio frequency (RF) power, such as that emitted by a radio transmitter. It is the total power in watts that would have to be radiated by a half-wave dipole antenna to give the same radiation intensity (signal strength or power flux density in watts per square meter) as the actual source antenna at a distant receiver located in the direction of the antenna's strongest beam (main lobe). ERP measures the combination of the power emitted by the transmitter and the ability of the antenna to direct that power in a given direction. It is equal to the input power to the antenna multiplied by the gain of the antenna. It is used in electronics and telecommunications, particularly in broadcasting to quantify the apparent power of a broadcasting station experienced by listeners in its reception area. An alternate parameter that measures the same thing is effec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Call Sign
In broadcasting and radio communications, a call sign (also known as a call name or call letters—and historically as a call signal—or abbreviated as a call) is a unique identifier for a transmitter station. A call sign can be formally assigned by a government agency, informally adopted by individuals or organizations, or even cryptographically encoded to disguise a station's identity. The use of call signs as unique identifiers dates to the landline railroad telegraph system. Because there was only one telegraph line linking all railroad stations, there needed to be a way to address each one when sending a telegram. In order to save time, two-letter identifiers were adopted for this purpose. This pattern continued in radiotelegraph operation; radio companies initially assigned two-letter identifiers to coastal stations and stations onboard ships at sea. These were not globally unique, so a one-letter company identifier (for instance, 'M' and two letters as a Marconi station ...

Digital Terrestrial Television
Digital terrestrial television (DTTV or DTT, or DTTB with "broadcasting") is a technology for terrestrial television in which land-based (terrestrial) television stations broadcast television content by radio waves to televisions in consumers' residences in a digital format. DTTV is a major technological advance over the previous analog television, and has largely replaced analog which had been in common use since the middle of the 20th century. Test broadcasts began in 1998 with the changeover to DTTV (aka Analog Switchoff (ASO), or Digital Switchover (DSO)) beginning in 2006 and is now complete in many countries. The advantages of ''digital'' terrestrial television are similar to those obtained by digitising platforms such as cable TV, satellite, and telecommunications: more efficient use of limited radio spectrum bandwidth, provision of more television channels than analog, better quality images, and potentially lower operating costs for broadcasters (after the initial up ...

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] |

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. United States In the United States, the Communications Act of 1934 requires that "the Commission s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
