Local Channels
DirecTV also offers local channels (CBS, ABC, NBC, Fox, PBS, The CW, Telemundo, Azteca, MyNetworkTV, ION Television (in markets that carry that network), and some independent stations) in 99% of U.S. markets. In markets that lack a CW affiliate, DirecTV includes WDCW from Washington, D.C. or XETV from San Diego.
Subscribers located where they cannot receive a decent terrestrial television signal and/or live in a tiny market that only has a couple of stations can receive feeds from New York and Los Angeles for CBS, ABC, NBC, and Fox, as well as a feed from the Washington, D.C. CW affiliate, though a waiver from the local affiliate stations may be required to allow this, approved at their discretion. National PBS and ION channels are also available.
In the largest markets, local channels are carried on the satellite at 101°W. In some smaller markets, the local channels are carried on a second satellite located at 119°W which requires a slightly larger dish with two or three LNBs or the newer Ka/Ku 5-LNB dish. In a few smaller markets, local stations are located on a satellite at 72.5°W that requires a second dish to be installed.
In late 2005, DirecTV began providing local HDTV channels to the largest markets, requiring newer receivers with a larger dish capable of receiving signals from up to five satellites at once. The Ku-band signals on the newer Ka/Ku dish are received from 101°W, 110°W, and 119°W, while Ka-band signals are from 99°W and 103°W.
Local television channels are transmitted over optical fiber links, Ku-band satellite uplink, microwave, and conventional terrestrial transmission to uplink centers located throughout the United States. DirecTV can provide true HD into hotels (Pro:Idiom). Cable companies have been able to provide true HD to hotels for over 2 years now with the installation of private video networks (FTTP to Coax conversion & Pro:Idiom) or with HFC HD video distribution systems (Pro:Idiom).

Famous quotes containing the words local and/or channels:
“The improved American highway system ... isolated the American-in-transit. On his speedway ... he had no contact with the towns which he by-passed. If he stopped for food or gas, he was served no local fare or local fuel, but had one of Howard Johnson’s nationally branded ice cream flavors, and so many gallons of Exxon. This vast ocean of superhighways was nearly as free of culture as the sea traversed by the Mayflower Pilgrims.”
—Daniel J. Boorstin (b. 1914)
“Not too many years ago, a child’s experience was limited by how far he or she could ride a bicycle or by the physical boundaries that parents set. Today ... the real boundaries of a child’s life are set more by the number of available cable channels and videotapes, by the simulated reality of videogames, by the number of megabytes of memory in the home computer. Now kids can go anywhere, as long as they stay inside the electronic bubble.”
—Richard Louv (20th century)
