KET ED
KET ED, known as the Education Channel, was a digital television programming service operated by PBS member network Kentucky Educational Television. The service provided programming from the Annenberg/CPB project, along with encore presentations of some PBS programming, and much of KET's locally produced in-house instructional television (ITV) productions. The service originated from KET's studios at the O. Leonard Press Telecommunications Center, at 600 Cooper Drive in Lexington, Kentucky. History In the beginning of the 2002–03 school year—which, in Kentucky, began in early August—the Kentucky Educational Television network launched three additional subchannels on the digital companion signals of all fifteen of its principal transmitters. In addition to a simulcast of their analog signals, the digital channels now offered three additional services, including a statewide relaunch of Louisville-based WKMJ-TV’s signal known as KET2. The DT3 and DT4 subchannels were bran ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Television Network
A television network or television broadcaster is a telecommunications network for distribution of television program content, where a central operation provides programming to many television stations or multichannel video programming distributor, pay television providers. Until the mid-1980s, television broadcast programming, programming in most countries of the world was dominated by a small number of terrestrial networks. Many early television networks (such as NBC, the Australian Broadcasting Corporation, ABC, or the BBC) evolved from earlier radio networks. Overview In countries where most networks broadcast identical, centrally originated content to all of their stations and where most individual television transmitters therefore operate only as large "broadcast relay station, repeater stations", the terms "television network", "television channel" (a numeric identifier or radio frequency) and "television station" have become mostly interchangeable in everyday language, wit ...

Instructional Television
Instructional television (ITV) is the use of television programs in the field of distance education. Educational television programs on instructional television may be less than one half hour long (generally 15 minutes in length) to help their integration into the classroom setting. These shows are often accompanied by teachers' guides that include material to help use this program in lessons. Instructional television programs have historically been shown during the daytime on Public Broadcasting Service (PBS) stations in the United States. However, fewer public television stations devote their airtime to ITV today than they do in the past; these days, ITV programs are either seen on a digital subchannel of non-commercial educational public television station, or passed on to a local educational-access television channel run by a public, educational, and government access (PEG) cable TV organization. Instructional television has been granted 20 microwave channels, administe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The CW
''The'' () is a grammatical article in English, denoting persons or things already mentioned, under discussion, implied or otherwise presumed familiar to listeners, readers, or speakers. It is the definite article in English. ''The'' is the most frequently used word in the English language; studies and analyses of texts have found it to account for seven percent of all printed English-language words. It is derived from gendered articles in Old English which combined in Middle English and now has a single form used with pronouns of any gender. The word can be used with both singular and plural nouns, and with a noun that starts with any letter. This is different from many other languages, which have different forms of the definite article for different genders or numbers. Pronunciation In most dialects, "the" is pronounced as (with the voiced dental fricative followed by a schwa) when followed by a consonant sound, and as (homophone of pronoun ''thee'') when followed by a ...

2006 United States Broadcast TV Realignment
In January 2006, America's two "second-tier" television networks, UPN and The WB, announced they would both cease operations on September 15 and 17, and their operations would be transferred to a new joint-venture "fifth" network, The CW. Meanwhile, Fox Television Stations (which owned several UPN and WB-affiliated stations in large cities that were blocked from affiliating with The CW) signed up with MyNetworkTV, a new "sixth" network owned by then-parent company News Corporation's Fox Entertainment Group. Background In January 1995, The WB Television Network and the United Paramount Network (UPN) were launched, each hoping to recreate the success of the Fox network, which had launched in October 1986 and became one of America's "major" networks through the successes of several early series (such as ''The Simpsons'', '' Married... with Children'', ''The X-Files'', ''Melrose Place'', ''Martin'', ''In Living Color'', '' COPS'', ''Beverly Hills, 90210'', and Fox Kids airings of th ...

The WB
The WB Television Network (for Warner Bros., or the "Frog Network", for its former mascot, Michigan J. Frog) was an American television network launched on broadcast television on January 11, 1995, as a joint venture between the Warner Bros. Entertainment division of Time Warner and the Tribune Broadcasting subsidiary of the Tribune Company, with the former acting as controlling partner.

Video On Demand
Video on demand (VOD) is a media distribution system that allows users to access videos without a traditional video playback device and the constraints of a typical static broadcasting schedule. In the 20th century, broadcasting in the form of over-the-air programming was the most common form of media distribution. As Internet and IPTV technologies continued to develop in the 1990s, consumers began to gravitate towards non-traditional modes of content consumption, which culminated in the arrival of VOD on televisions and personal computers. Unlike broadcast television, VOD systems initially required each user to have an Internet connection with considerable bandwidth to access each system's content. In 2000, the Fraunhofer Institute IIS developed the JPEG2000 codec, which enabled the distribution of movies via Digital Cinema Packages. This technology has since expanded its services from feature-film productions to include broadcast television programmes and has led to lower bandw ...

Central Time Zone
The North American Central Time Zone (CT) is a time zone in parts of Canada, the United States, Mexico, Central America, some Caribbean Islands, and part of the Eastern Pacific Ocean. Central Standard Time (CST) is six hours behind Coordinated Universal Time (UTC). During summer, most of the zone uses daylight saving time (DST), and changes to Central Daylight Time (CDT) which is five hours behind UTC. The largest city in the Central Time Zone is Mexico City; the Mexico City metropolitan area is the largest metropolitan area in the zone and in North America. Regions using (North American) Central Time Canada The province of Manitoba is the only province or territory in Canada that observes Central Time in all areas.

High-definition Television
High-definition television (HD or HDTV) describes a television system which provides a substantially higher image resolution than the previous generation of technologies. The term has been used since 1936; in more recent times, it refers to the generation following standard-definition television (SDTV), often abbreviated to HDTV or HD-TV. It is the current de facto standard video format used in most broadcasts: terrestrial broadcast television, cable television, satellite television and Blu-ray Discs. Formats HDTV may be transmitted in various formats: * 720p (1280 horizontal pixels × 720 lines): 921,600 pixels * 1080i (1920×1080) interlaced scan: 1,036,800 pixels (~1.04 MP). * 1080p (1920×1080) progressive scan: 2,073,600 pixels (~2.07 MP). ** Some countries also use a non-standard CEA resolution, such as 1440×1080i: 777,600 pixels (~0.78 MP) per field or 1,555,200 pixels (~1.56 MP) per frame When transmitted at two megapixels per frame, HDTV provides about five times ...

Distance Learning
Distance education, also known as distance learning, is the education of students who may not always be physically present at a school, or where the learner and the teacher are separated in both time and distance. Traditionally, this usually involved correspondence courses wherein the student corresponded with the school via mail. Distance education is a technology mediated modality and has evolved with the evolution of technologies such as video conferencing, TV, and internet. Today, it usually involves online education and the learning is usually mediated by some form of technology. A distance learning program can be completely distance learning, or a combination of distance learning and traditional classroom instruction (called hybrid or blended). Other modalities include distance learning with complementary virtual environment or teaching in virtual environment (e-learning). Massive open online courses (MOOCs), offering large-scale interactive participation and open access ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Direct Broadcast Satellite
Satellite television is a service that delivers television programming to viewers by relaying it from a communications satellite orbiting the Earth directly to the viewer's location. The signals are received via an outdoor parabolic antenna commonly referred to as a satellite dish and a low-noise block downconverter. A satellite receiver then decodes the desired television program for viewing on a television set. Receivers can be external set-top boxes, or a built-in television tuner. Satellite television provides a wide range of channels and services. It is usually the only television available in many remote geographic areas without terrestrial television or cable television service. Modern systems signals are relayed from a communications satellite on the X band (8–12 GHz) or Ku band (12–18 GHz) frequencies requiring only a small dish less than a meter in diameter. The first satellite TV systems were an obsolete type now known as television receive-only. Thes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
