The Sign on script is essentially a long version of the Station ID. Wikipedia gives the following elements as being common on a Startup script:
- For television stations or radio stations that cut-off their signal during off-broadcast hours, a test pattern and/or 1000hZ tone may be broadcast fifteen to twenty minutes before the actual sign-on.
- A signal to turn on remote transmitters may be played—this is usually a series of touch tones.
- Technical information provided, such as the call sign, Transmitter power output|transmitter power, broadcast translators used, transmitter locations, and Studio/transmitter link.
- On television stations, a video and/or montage set to the national anthem or another patriotic piece of music may be played; on radio stations this would just consist of the music, usually the national anthem. The accompanying television video usually involves images of the National flag, head of state, military, national symbols, or other nationalistic imagery, particularly on state owned broadcasters.
- Ownership information about the station, and a list of related organizations.
- A "good morning" greeting to viewers or listeners.
- Contact information, such as street and mailing addresses, telephone number, email, and website details.
- A prayer or other religious acknowledgement, particularly in countries with a state religion, in theocracies, and on religious broadcasters. For example sign-ons in Cambodia, Thailand, Sri Lanka and Vietnam typically include a quote from Buddha, and those in Indonesia, Saudi Arabia, Lebanon, Kazakhstan and Malaysia generally include an Islamic reading from the [uran, a Muslim quote, or a call for Azan and Fajr Prayer and those in the Philippines, Russia, Canada and the United States of America include a Christian prayer or hymn of some type.
- A program guide for the upcoming programs, or the day's programs.
- A disclaimer that station programming is taped, aired live, or originates from a television or radio network.
- Another disclaimer that programs are for personal use only (sometimes with information on copyright restrictions), and a statement that businesses cannot profit from showing them by applying a cover charge for viewing.
- A statement of commitment to quality; this may be in the form of a recognized standard, such as the United States National Association of Broadcasters' "Seal of Good Practice".
- A station identification, including some or all of the television channel, FM frequency, call sign, branding, and a clock ident.
- Generally a station jingle or slogan will be played, accompanied on television with video clips featuring station programming or personalities.
JunkRadio's usage of this is to set the tone, introduce the broadcast, cover important copyright notices, and introduce the programmes to follow.
