Sign-off

Sign-off (or closedown) 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. It is the opposite to a sign-on (or startup), which usually takes place at the start of the day.

Overview

Sign-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 (cable/satellite boxes, digital TVs/converter boxes) to display error messages.

Sign

A sign is an object, quality, event, or entity whose presence or occurrence indicates the probable presence or occurrence of something else. A natural sign bears a causal relation to its object—for instance, thunder is a sign of storm, or medical symptoms signify a disease. A conventional sign signifies by agreement, as a full stop signifies the end of a sentence; similarly the words and expressions of a language, as well as bodily gestures, can be regarded as signs, expressing particular meanings. The physical objects most commonly referred to as signs (notices, road signs, etc., collectively known as signage) generally inform or instruct using written text, symbols, pictures or a combination of these.

The philosophical study of signs and symbols is called semiotics; this includes the study of semiosis, which is the way in which signs (in the semiotic sense) operate.

Lord's Prayer

The Lord's Prayer, also called the Our Father and the Pater Noster, is a venerated Christian prayer that, according to the New Testament, was taught by Jesus to his disciples. Two forms of it are recorded in the New Testament: a longer form in the Gospel of Matthew as part of the Sermon on the Mount, and a shorter form in the Gospel of Luke as a response by Jesus to a request by "one of his disciples" to teach them "to pray as John taught his disciples" concludes with "deliver us from evil" in Matthew, and with "lead us not into temptation" in Luke. The first three of the seven petitions in Matthew address God; the other four are related to human needs and concerns. The liturgical form is the Matthean. Some Christians, particularly Protestants, conclude the prayer with a doxology, a later addendum appearing in some manuscripts of Matthew.

The context of the prayer in Matthew is a discourse deploring people who pray ostentatiously.

In biblical criticism, the prayer's absence in the Gospel of Mark together with its occurrence in Matthew and Luke has caused scholars who accept the two-source hypothesis (against other document hypotheses) to conclude that it is probably a logion original to Q.
