) is the term used to describe the beginning of operations for a television station
. It is the opposite to a sign-off
As with sign-offs, sign-ons vary from country to country, and from station to station.
In the United States
, sign-ons are often the exact reverse of a sign-off
. Commercial stations often sign on between 5-6 a.m., while some public stations may not sign on until as late as 7:30 a.m. Television sign-ons are very rare these days as most stations operate 24 hours a day. In these cases, the sign-on sequence is shown between commercials or before a program around the 6 a.m. hour (5 a.m. in the Central and Mountain time zones); for instance, before the start of a network's early morning newscast, or that station's morning news show.
The sign-on sequence often includes the following:
- In some cases, a signal to turn on any remote transmitters—usually a series of Touch Tones.
- A video and/or photo montage set to the national anthem or another patriotic piece.
- A "good morning"-type greeting to viewers.
- Technical information, such as the call sign, transmitter power, translators used, transmitter locations and STL links.
- Ownership of the station.
- Contact information – such as street and mailing addresses, and/or telephone number.
- List of related organizations.
- A disclaimer that station programming is taped, aired live, or originates from a television network. Some stations also air another disclaimer that programs are for personal use only (previously only at time of viewing; this has been appended with the spread of VHS and DVR devices), and businesses cannot profit from showing them by applying a cover charge for viewing.
- A commitment to quality (or perhaps, a slogan). Prior to the early 1980s, this was generally in the form of the National Association of Broadcasters' "Seal of Good Practice".
- An identification of the station.
The above is often followed by a station jingle, usually played over a montage of local video clips.
For stations that cut off their signal during off-broadcast hours, a test pattern may appear 15-20 minutes before the actual sign-on.
On radio stations owned and operated by the CBC, a short introduction is aired, before it goes into its announcement. On CBC/Radio Canada TV stations, the Coat of arms of Canada is displayed, followed by a video montage accompanied by the national anthem (In the mid 90's, the anthem was played as a cartoon fly by across Canada was happening from a bird's eye view), and a special "broadcast day bumper" video sequence, which includes a legal ID showing callsign, channel number and city of licence. The practice has ended, since the english CBC radio and TV stations went to 24-hour transmission in late 2006. In Saskatchewan, CBC TV Stations went on to be 24-hour transmission since the beginning of Torino 2006 Olympic Games. For the Radio Canada stations however, this sign-on practice still continues.

When the second hand hits the top of the minute, the national anthem will play after which a morning muslim prayer is said.
