Television In El Salvador
Television in El Salvador began in 1956 in black and white on YSEB-TV, which would bring attention to the radio broadcasting industry in the 1960s. It was so much so that it was part of the Salvadoran Association Broadcasting (ASDER) in 1964 to confront stagnation, in response to the political crisis during the era of military authoritarianism. Since the birth of privatization, Salvadoran television survived with the support of viewers and the growth of the industry that became part of one of the most important communication media, media. Currently, there are 42 television channel concessions in total: 35 of these are private, five religious and two public. In addition, eighteen television channels have national coverage and 24 channels are regional; including international television services, normally distributed by cable and satellite. Salvadoran television is in charge of the General Superintendency of Electricity and Telecommunications (SIGET) since 1996, being the successor o ...

Canal 33 (El Salvador)
El 33 () is Catalonia's second public television channel. It belongs to Televisió de Catalunya, a subsidiary of the CCMA. History The idea of a second channel in Catalonia began in 1988, with a controversy between Televisión Española, which planned to launch a third channel exclusively for Catalonia and produced solely in Sant Cugat del Vallès, but the CCRTV (Corporació Catalana de Ràdio i Televisió) had planned to launch the second channel called Canal 33. This provoked a struggle between the Spanish government and the Generalitat de Catalunya (Catalan government), which was not resolved until 1989. Televisió de Catalunya began its trial broadcasts for Canal 33 on September 10, 1988 (the eve of National Day of Catalonia), much to the surprise for both Spanish Government and the Generalitat. UHF Channel 47 in Barcelona was allocated to this channel. The Director-General of Telecommunications ordered TVE to interfere with the new channel's signal, while Televisió de ...

Digital Television Transition
The digital television transition, also called the digital switchover (DSO), the analogue switch/sign-off (ASO), the digital migration, or the analogue shutdown, is the process in which older analogue television broadcasting technology is converted to and replaced by digital television. Conducted by individual nations on different schedules, this primarily involves the conversion of analogue terrestrial television broadcasting infrastructure to digital terrestrial (DTT), a major benefit being extra frequencies on the radio spectrum and lower broadcasting costs, as well as improved viewing qualities for consumers. The transition may also involve analogue cable conversion to digital cable or Internet Protocol television, as well as analog to digital satellite television. Transition of land based broadcasting was begun by some countries around 2000. By contrast, transition of satellite television systems was well underway or completed in many countries by this time. It is an inv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ISDB-T
Integrated Services Digital Broadcasting (ISDB; Japanese: , ''Tōgō dejitaru hōsō sābisu'') is a Japanese broadcasting standard for digital television (DTV) and digital radio. ISDB supersedes both the NTSC-J analog television system and the previously used MUSE Hi-vision analog HDTV system in Japan. An improved version of ISDB-T (ISDB-T International) will soon replace the NTSC, PAL-M, and PAL-N broadcast standards in South America and the Philippines. Digital Terrestrial Television Broadcasting (DTTB) services using ISDB-T started in Japan in December 2003, and since then, many countries have adopted ISDB over other digital broadcasting standards. A newer and "advanced" version of the ISDB standard (that will eventually allow up to 8K terrestrial broadcasts and 1080p mobile broadcasts via the VVC codec, including HDR and HFR) is currently under development. Countries and territories using ISDB-T Asia * * (officially adopted ISDB-T, started broadcasting in digital) ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ATSC
Advanced Television Systems Committee (ATSC) standards are an American set of standards for digital television transmission over terrestrial, cable and satellite networks. It is largely a replacement for the analog NTSC standard and, like that standard, is used mostly in the United States, Mexico, Canada, and South Korea. Several former NTSC users, such as Japan, have not used ATSC during their digital television transition, because they adopted other systems such as ISDB developed by Japan, and Digital Video Broadcasting, DVB developed in Europe, for example. The ATSC standards were developed in the early 1990s by the Grand Alliance (HDTV), Grand Alliance, a consortium of electronics and telecommunications companies that assembled to develop a specification for what is now known as HDTV. The standard is now administered by the Advanced Television Systems Committee. It includes a number of patented elements, and licensing is required for devices that use these parts of the stan ...

Digital Television
Digital television (DTV) is the transmission of television signals using digital encoding, in contrast to the earlier analog television technology which used analog signals. At the time of its development it was considered an innovative advancement and represented the first significant evolution in television technology since color television in the 1950s. Modern digital television is transmitted in high-definition television (HDTV) with greater resolution than analog TV. It typically uses a widescreen aspect ratio (commonly 16:9) in contrast to the narrower format of analog TV. It makes more economical use of scarce radio spectrum space; it can transmit up to seven channels in the same bandwidth as a single analog channel, and provides many new features that analog television cannot. A transition from analog to digital broadcasting began around 2000. Different digital television broadcasting standards have been adopted in different parts of the world; below are the more widel ...

Sky México
The sky is an unobstructed view upward from the surface of the Earth. It includes the atmosphere and outer space. It may also be considered a place between the ground and outer space, thus distinct from outer space. In the field of astronomy, the sky is also called the celestial sphere. This is an abstract sphere, concentric to the Earth, on which the Sun, Moon, planets, and stars appear to be drifting. The celestial sphere is conventionally divided into designated areas called constellations. Usually, the term ''sky'' informally refers to a perspective from the Earth's surface; however, the meaning and usage can vary. An observer on the surface of the Earth can see a small part of the sky, which resembles a dome (sometimes called the ''sky bowl'') appearing flatter during the day than at night. In some cases, such as in discussing the weather, the sky refers to only the lower, denser layers of the atmosphere. The daytime sky appears blue because air molecules scatter shor ...

Satellite Television
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] |
