Cable television is a system of delivering television programming to consumers via radio frequency (RF) signals transmitted through coaxial cables , or in more recent systems, light pulses through fibre-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 , or satellite television , in which the television signal is transmitted over-the-air by radio waves from a communications satellite and received by a satellite dish on the roof. FM radio programming, high-speed Internet , telephone services , and similar non-television services may also be provided through these cables. Analog television was standard in the 20th century, but since the 2000s, cable systems have been upgraded to digital cable operation.
78-556: TLC is an American multinational cable and satellite television network owned by the Networks division of Warner Bros. Discovery . First established in 1980 as The Learning Channel , it initially focused on educational and instructional programming. By the late 1990s, after an acquisition by Discovery, Inc. earlier in the decade, the network began to pivot towards reality television programming — predominantly focusing on programming involving lifestyles and personal stories — to

Under Discovery, The Learning Channel continued to focus primarily on instructional and educational programming for much of
312-405: A dedicated analog circuit-switched service. Other advantages include better voice quality and integration to a Voice over Internet Protocol (VoIP) network providing cheap or unlimited nationwide and international calling. In many cases, digital cable telephone service is separate from cable modem service being offered by many cable companies and does not rely on Internet Protocol (IP) traffic or
390-436: A given location, cable distribution lines must be available on the local utility poles or underground utility lines. Coaxial cable brings the signal to the customer's building through a service drop , an overhead or underground cable. If the subscriber's building does not have a cable service drop, the cable company will install one. The standard cable used in the U.S. is RG-6 , which has a 75 ohm impedance , and connects with
468-543: A high elevation. At the outset, cable systems only served smaller communities without television stations of their own, and which could not easily receive signals from stations in cities because of distance or hilly terrain. In Canada, however, communities with their own signals were fertile cable markets, as viewers wanted to receive American signals. Rarely, as in the college town of Alfred, New York , U.S. cable systems retransmitted Canadian channels. Although early ( VHF ) television receivers could receive 12 channels (2–13),
546-466: A higher rate. At the local headend, the feed signals from the individual television channels are received by dish antennas from communication satellites . Additional local channels, such as local broadcast television stations, educational channels from local colleges, and community access channels devoted to local governments ( PEG channels) are usually included on the cable service. Commercial advertisements for local business are also inserted in
624-405: A local VHF television station broadcast. Local broadcast channels were not usable for signals deemed to be a priority, but technology allowed low-priority signals to be placed on such channels by synchronizing their blanking intervals . TVs were unable to reconcile these blanking intervals and the slight changes due to travel through a medium, causing ghosting . The bandwidth of the amplifiers also
702-463: A microwave-based system, may be used instead. Coaxial cables are capable of bi-directional carriage of signals as well as the transmission of large amounts of data . Cable television signals use only a portion of the bandwidth available over coaxial lines. This leaves plenty of space available for other digital services such as cable internet , cable telephony and wireless services, using both unlicensed and licensed spectra. Broadband internet access

He opened his own fashion design school and operated it during the 1950s. In 1956, he was elected president of the Hollywood Beauty League, an organization dedicated to promoting Los Angeles as a cultural hub. In the 1970s, Trippon began presenting
858-564: A rarity, found in an ever-dwindling number of markets. Analog television sets are accommodated, their tuners mostly obsolete and dependent entirely on the set-top box. Cable television is mostly available in North America , Europe , Australia , Asia and South America . Cable television has had little success in Africa , as it is not cost-effective to lay cables in sparsely populated areas. Multichannel multipoint distribution service ,

In early March 2008, TLC launched a new imaging campaign, "Life Surprises". This new slogan came as TLC began to shift even more to personal stories, and away from the once-dominating home improvement shows. Programs focused on family life became the core of
1482-433: A time when Discovery itself was overhauling much, and in some cases competition series of its own programming, introducing shows like American Chopper (which Discovery moved to TLC for a time). Much of the older, more educationally focused programming could still be found dispersed amongst other channels owned by Discovery Communications. On March 27, 2006, the network launched a new look and promotional campaign, dropping
1560-605: A type F connector . The cable company's portion of the wiring usually ends at a distribution box on the building exterior, and built-in cable wiring in the walls usually distributes the signal to jacks in different rooms to which televisions are connected. Multiple cables to different rooms are split off the incoming cable with a small device called a splitter . There are two standards for cable television; older analog cable, and newer digital cable which can carry data signals used by digital television receivers such as high-definition television (HDTV) equipment. All cable companies in

By 1982, ACSN claimed that it "achieved the fastest rate of growth of all basic cable programming services," with availability on around 70 cable affiliates reaching 1.5 million subscribers; by this point, 70 universities granted academic credit for telecourses carried on the network. On January 1, 1984, the network shortened its name to The Learning Channel . The channel mostly featured documentary content pertaining to nature, science, history, current events, medicine, technology, cooking, home improvement, and other information-based topics. A notable example of such programming
