A sign on or startup is the beginning of operations for a radio or television station, generally at the start of each day. It is the opposite of a sign off or closedown, which is the sequence of operations involved when a radio or television station shuts down its transmitters and goes off the air for a predetermined period generally, this occurs during the overnight hours. Sign oneditSign ons, like sign offs, vary from country to country, from station to station, and from time to time however, most follow a similar general pattern. Many stations follow the reverse process to their sign off sequence at the close of the day. It is common for sign ons to be followed by a networks early morning newscast, or their morning or breakfast show. While both sign ons and sign offs have become less common with the increasing prevalence of twenty four hour a day, seven day a week broadcasting, they are still conducted by a number of stations around the world. For broadcasters that do still close for a period each day, this station close is most often during the early hours of the morning, with the daily sign on typically occurring between 5 0. However, in some countries with more limited broadcast coverage, such as North Korea, sign on may be as late as 5 0. A particular type of AM radio station known as a daytimer usually only operates during daytime hours, and will therefore run a sign on sequence each day.

Sign on sequenceeditThe sign on sequence may include some or all of the following stages, but not necessarily in this order For television stations or radio stations that cut off their signal during off broadcast hours, a test pattern or 1. Hz tone or music or radio station may be broadcast fifteen to twenty minutes before the actual sign on. A signal to turn on remote transmitters may be playedthis is usually a series of touch tones. On radio stations, especially international stations on shortwave, an interval signal may be played, usually for 3 to 5 minutes before the actual broadcast starts. Technical information provided, such as the station identification call sign and city of license, transmitter power, frequency or channel number, translators used, transmitter locations, list of broadcast engineers in the Philippines, and studiotransmitter links STL. On television stations, a video or photo 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 states, national heroes, national 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 Sri Lanka, Vietnam, Cambodia, Laos and Thailand typically include a quote from Gautama Buddha, those in Saudi Arabia, Brunei, Malaysia and Indonesia generally include an Islamic reading from the Quran, a Muslim quote, or a call for Azan and Fajr prayer, those in the Philippines except in the Autonomous Region of Muslim Mindanao, Italy, Russia except for some republics, Canada and the United States include a Christian prayer, responsorial psalm or hymn of some type and stations in India and China have a prayer of any religion depending on the day. A program guide for the upcoming programs, or the days programs. A disclaimer that station programming is taped, aired live, or originates from a television or radio network.

Philippines KBP Broadcast Code of the Kapisanan ng mga Brodkaster ng PilipinasAssociation of Broadcasters of the PhilippinesA station identification, including some or all of the television channel, AM or FMfrequency, 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. While most of these sign on steps are done as a service to the public, or for advertising reasons, some of them may be required by the government of the country. Sign offeditSign offs, like sign ons, vary from country to country, from station to station, and from time to time however, most follow a similar general pattern. Many stations follow the reverse process to their sign on sequence at the start of the day. Sign off messages can be initiated by a broadcast automation system just as for other television programming, and automatic transmission systems can cut off the carrier signal and trigger the actual shutdown of the transmitter by remote control. Generally, after the carrier signal is cut, the viewer only sees or hears static after an analog television station signs off. Digital stations will likely display a message after the sign off however, they may simply cut to a black screen with no sound. Occasionally, the signal is cut off entirely, causing digital broadcast receivers cablesatellite boxes, digital TVsconverter boxes to display error messages. Both sign offs and sign ons have become less common with the increasing prevalence of twenty four hours a day, seven days a week broadcasting. They are, however, still conducted by a number of stations around the world, often by stations catering to small markets or those in less developed countries, or when stations need to shut down for transmitter maintenance. Another consideration for whether providers shutdown is power consumption aerial signals, such as those for UHFanalog TV transmissions, can require tens of thousands of watts of power, making electricity a major expense, while power consumption would usually be considerably lower for cable and satellite providers. In relation to costs, viewer numbers are also a consideration. Another consideration is the licence issued by the government which indicates when their transmitters can be operated. For broadcasters which do still close for a period each day, the station close most often takes place overnight or during the early hours of the morning. The daily sign off typically occurs between around 1. Sign off may also vary depending on the day of the week for example some broadcasters may run for 2. Saturday nights, but sign off and close during the week when there are lower viewer numbers. Seasonality is also a consideration where some stationsnetworks stay open for 2. Many stations, while no longer conducting a sign off and being off air for a period of time each day, instead run low cost programming during those times of low viewer numbers.
