A broadcast relay station, also known as a satellite station, relay transmitter, broadcast translator (U.S.), re-broadcaster (Canada), repeater (two-way radio) or complementary station (Mexico), is a broadcast transmitter which repeats (or transponds) the signal of a radio or television station to an area not covered by the originating station.

These expand the broadcast range of a television or radio station beyond the primary signal's original coverage or improves service in the original coverage area. The stations may be (but are not usually) used to create a single-frequency network. They may also be used by an AM or FM radio station to establish a presence on the other band.

Tokyo Skytree (東京スカイツリー, Tōkyō Sukaitsurī; [toːkʲoː sɯ̥kaitsɯriː] ), also written as Tokyo Sky Tree, is a broadcasting and observation tower, located in Sumida, Tokyo, Japan. It has been the tallest tower in Japan since opening in 2012, and reached its full height of 634 m (2,080 ft) in early 2011, making it the tallest tower in the world, displacing the Canton Tower, and the third tallest structure in the world behind Merdeka 118 (678.9 m or 2,227 ft) and Burj Khalifa (829.8 m or 2,722 ft).

The tower is the primary television and radio broadcast site for the Kantō region; the older Tokyo Tower no longer gives complete digital terrestrial television broadcasting coverage because it is surrounded by high-rise buildings. Skytree was completed on Leap Day, 29 February 2012, with the tower opening to the public on 22 May 2012. The tower is the centerpiece of a large commercial development funded by Tobu Railway (which owns the complex) and a group of six terrestrial broadcasters headed by NHK. Trains stop at the adjacent Tokyo Skytree Station and nearby Oshiage Station. The complex is 7 km (4.3 mi) northeast of Tokyo Station. Sumida Aquarium is in the Tokyo Solamachi complex.

A broadcast network (sometimes called a terrestrial network) is a group of radio stations, television stations, or other electronic media outlets, that form an agreement to air, or broadcast, content from a centralized source. For example, ABCTooltip American Broadcasting Company, CBSTooltip CBS and NBCTooltip NBC (U.S.), CBC/Radio-CanadaTooltip Canadian Broadcasting Corporation (Canada), the BBC (UK), the ABCTooltip Australian Broadcasting Corporation (Australia), ARD (Germany), PTVTooltip People's Television Network and IBCTooltip Intercontinental Broadcasting Corporation (Philippines), KBSTooltip Korean Broadcasting System (South Korea), and NHK (Japan) are TV networks that provide programming for local terrestrial television station affiliates to air using signals that can be picked up by the home television sets of local viewers. Networks generally, but not always, operate on a national scale; that is, they cover an entire country.

Streaming media, Internet radio, and webcasting are sometimes considered forms of broadcasting despite the lack of terrestrial stations; its practitioners may also be called "broadcasters" or even "broadcast networks".

NHK General TV (NHK総合テレビジョン, NHK Sōgō Terebijon), abbreviated on-screen as NHK G, is the main television service of NHK, the Japanese public broadcaster. Its programming includes news, drama, quiz/variety shows, music, sports, anime, and specials which compete directly with the output of its commercial counterparts. The channel is well known for its nightly newscasts, regular documentary specials, and popular historical dramas. A similar counterpart would be, to a lesser extent, BBC One in the UK. Among the programs NHK General TV broadcasts are the annual New Year's Eve spectacular Kōhaku Uta Gassen, the year-long Taiga drama, and the daytime Asadora.

The name is often abbreviated in Japanese to Sōgō Terebi (総合テレビ) ("GTV" and "NHK G" are also used). The word Sōgō (general) serves to differentiate the channel from NHK's other television services, NHK Educational TV, NHK BS 1, NHK BS 2 (closed in 2011) and NHK BS HI (changed to BS Premium).

NHK Educational TV (NHK教育テレビジョン, Enu eichi kei Kyōiku terebijon), abbreviated on-screen as NHK E, is the second television service of NHK (Japan Broadcasting Corporation). It is a sister service of NHK General TV, showing programs of a more educational, documentaries, cultural, children's or intellectual nature, periodically also showing anime, and also airing programming from Nickelodeon. A similar counterpart would be PBS of the United States (or to a lesser extent BBC Two, BBC Three, BBC Four, CBBC and CBeebies of the UK). NHK displays a watermark "NHK E" at the upper right for its digital TV broadcast. In 2010, NHK began using the abbreviation E Tele (イーテレ, Ī Tere).
