Simulcast in the context of "Satellite radio"

Radio broadcasting is the transmission of electromagnetic radiation (radio waves) to receivers over a wide area. Most broadcasts are audio (sound), sometimes with embedded metadata. Listeners require a broadcast radio receiver to receive these signals. "Terrestrial" broadcasts, including AM, FM, and DAB stations, originate from land-based transmitters, whereas "satellite radio" signals originate from a satellite in Earth orbit.

Stations may produce their own programming or be affiliated with a radio network that provides content either through broadcast syndication or by simulcasting, or both. The most common transmission technologies are analog and digital. Analog radio uses one of two modulation methods: amplitude modulation (AM) or frequency modulation (FM). Digital radio stations transmit using one of several digital audio standards, such as DAB (Digital Audio Broadcasting), HD Radio, or DRM (Digital Radio Mondiale).

HD Radio (HDR) is a trademark for in-band on-channel (IBOC) digital radio broadcast technology. HD radio generally simulcasts an existing analog radio station in digital format with less noise and with additional text information. HD Radio is used primarily by FM radio stations in the United States, U.S. Virgin Islands, Canada, Mexico and the Philippines, with a few implementations outside North America.

HD Radio transmits the digital signals in unused portions of the same band as the analog AM and FM signals. As a result, radios are more easily designed to pick up both signals, which is why the HD in HD Radio is sometimes referred to stand for Hybrid Digital, not "High Definition". Officially, HD is not intended to stand for any term in HD Radio, it is simply part of iBiquity's trademark, and does not have any meaning on its own. HD Radios tune into the station's analog signal first and then look for a digital signal. The European DRM system shares channels similar to HD Radio, but the European DAB system uses different frequencies for its digital transmission.

Sailor Moon (Japanese: 美少女戦士セーラームーン, Hepburn: Bishōjo Senshi Sērā Mūn; originally translated as Pretty Soldier Sailor Moon, later Pretty Guardian Sailor Moon) is a Japanese manga series written and illustrated by Naoko Takeuchi. It was originally serialized in Kodansha's shōjo manga magazine Nakayoshi from 1991 to 1997; the 60 individual chapters (later reorganized into 52) and several side stories were compiled into 18 tankōbon volumes. Set in Tokyo in the 1990s, the series follows the adventures of a schoolgirl named Usagi Tsukino as she transforms into the eponymous character to search for a magical artifact, the "Legendary Silver Crystal" (「幻の銀水晶」, Maboroshi no Ginsuishō; lit. "Phantom Silver Crystal"). She leads a group of comrades, the Sailor Soldiers, called Sailor Guardians in later editions, as they battle against villains to prevent the theft of the Silver Crystal and the destruction of the Solar System.

The manga was written in conjunction with the airing of an anime series produced by Toei Animation, which was broadcast in Japan from 1992 to 1997. Toei also developed three animated feature films, a television special, and three short films based on the anime. A live-action television adaptation, Pretty Guardian Sailor Moon, aired from 2003 to 2004, and a second anime series, Sailor Moon Crystal, began simulcasting in 2014. The manga series was licensed for an English release by Kodansha Comics in North America, and in Australia and New Zealand by Random House Australia. The entire anime series has been licensed by Viz Media for an English-language release in North America and by Madman Entertainment in Australia and New Zealand.

BBC HD was a high-definition television channel owned by the BBC. The channel was initially run as a trial from 15 May 2006 until becoming a full service on 5 April 2008 before its discontinuation on 25 March 2013. It broadcast only during the afternoon and evening and only broadcast material shot in high definition, either in a simulcast with another channel or by inserting a repeat of an HD programme.

The channel featured a mix of programmes from the channels BBC One, BBC Two, BBC Three, BBC Four, CBBC and CBeebies, although earlier and later in its existence programmes from BBC One and BBC Two were given priority. All programmes that aired on the UK version of the channel were produced in high definition. The channel also carried coverage of sport and music events, with some coverage being broadcast in experimental formats such as 3D television.

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 television (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 analogue to digital satellite television. Transition of land based broadcasting had begun in 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 involved process because the existing analogue television receivers owned by viewers cannot receive digital broadcasts; viewers must either purchase new digital TVs, or digital converter boxes which have a digital tuner and change the digital signal to an analogue signal or some other form of a digital signal (i.e. HDMI) which can be received on the older TV. Usually during a transition, a simulcast service is operated where a broadcast is made available to viewers in both analogue and digital at the same time. As digital becomes more popular, it is expected that the existing analogue services will be removed. In most places this has already happened, where a broadcaster has offered incentives to viewers to encourage them to switch to digital. Government intervention usually involves providing some funding for broadcasters and, in some cases, monetary relief to viewers, to enable a switchover to happen by a given deadline. In addition, governments can also have a say with the broadcasters as to what digital standard to adopt – either DVB-T2 ATSC Governments can also require all receiving equipment sold in a country to support the necessary digital 'tuner'.

Francis Dayle "Chick" Hearn (November 27, 1916 – August 5, 2002) was an American sportscaster who was the play-by-play announcer for the Los Angeles Lakers of the National Basketball Association for 41 years, as well as the team's assistant general manager for seven years beginning in 1972. Hearn was the first broadcaster named to the Naismith Basketball Hall of Fame. Hearn is remembered for his rapid fire, staccato broadcasting style, associated with colorful phrases such as slam dunk, air ball, and no harm, no foul that have become common basketball vernacular. Hearn broadcast 3,338 consecutive Lakers games starting on November 21, 1965. Most of Hearn's games in the television era were simulcast on both radio and television, even after most teams chose to use different announcers for the different media.
