Cable TV

Cable television is a system of delivering television programming to paying subscribers via radio frequency (RF) signals transmitted through coaxial cables or light pulses through fiber-optic cables. This contrasts with broadcast television, in which the television signal is transmitted over the air by radio waves and received by a television antenna attached to the television. FM radio programming, high-speed Internet, telephone service, and similar non-television services may also be provided through these cables.

A cable channel (sometimes known as a cable network) is a television network available via cable television. When available through satellite television, including direct broadcast satellite providers such as DirecTV, Dish Network and BSkyB, as well as via IPTV, it is referred to as a satellite channel. Alternative terms include non-broadcast channel or programming service, the latter being mainly used in legal contexts. Examples of cable/satellite channels/cable networks available in many countries are HBO, MTV, Cartoon Network, E!, Eurosport and CNN International.

The abbreviation CATV is often used for cable television. It originally stood for Community Access Television or Community Antenna Television, from cable television’s origins in 1948: in areas where over-the-air reception was limited by distance from transmitters or mountainous terrain, large “community antennas” were constructed, and cable was run from them to individual homes. The origins of cable broadcasting are even older as radio programming was distributed by cable in some European cities as far back as 1924.

Analog television was standard in the 20th century, but since then cable systems have been upgraded to digital cable operation.

San Diego

San Diego (/ˌsæn dˈɡ/Spanish for “Saint Didacus“; Spanish: [san ˈdje.ɣo]) is a major city in CaliforniaUnited States. It is in San Diego County, on the coast of the Pacific Ocean in Southern California, approximately 120 miles (190 km) south of Los Angeles and immediately adjacent to the border with Mexico.

With an estimated population of 1,394,928 as of July 1, 2015,[9] San Diego is the eighth-largest city in the United States andsecond-largest in California. It is part of the San Diego–Tijuana conurbation, the second-largest transborder agglomerationbetween the US and a bordering country after Detroit–Windsor, with a population of 4,922,723 people.[11] San Diego has been called “the birthplace of California”.[12] It is known for its mild year-round climate, natural deep-water harbor, extensive beaches, long association with the United States Navy, and recent emergence as a healthcare and biotechnology development center.

Historically home to the Kumeyaay people, San Diego was the first site visited by Europeans on what is now the West Coast of the United States. Upon landing in San Diego Bay in 1542, Juan Rodríguez Cabrillo claimed the area for Spain, forming the basis for the settlement of Alta California 200 years later. The Presidio and Mission San Diego de Alcalá, founded in 1769, formed the first European settlement in what is now California. In 1821, San Diego became part of the newly independent Mexico, which reformed as the First Mexican Republic two years later. In 1850, California became part of the United States following the Mexican–American War and the admission of California to the union.

The city is the seat of San Diego County and is the economic center of the region as well as the San Diego–Tijuanametropolitan area. San Diego’s main economic engines are military and defense-related activities, tourism, international trade, and manufacturing. The presence of the University of California, San Diego (UCSD), with the affiliated UCSD Medical Center, has helped make the area a center of research in biotechnology.
