Station ID

Station identification (ident, network ID or channel ID) is the practice of radio or television stations or networks identifying themselves on-air, typically by means of a call sign or brand name (sometimes known, particularly in the United States, as a "sounder" or "stinger", more generally as a station or network ID). This may be to satisfy requirements of licensing authorities, a form of branding or a combination of both. As such, it is closely related to production logos used in television and cinema, alike.

Station identification used to be done regularly by an announcer at the halfway point during the presentation of a television program, or in between programs.

Idents are known as a montage in Thailand, and as an interlude in Cambodia and Vietnam.

Station IDs in the Philippines differ from the original concept. Instead of a way to identify television networks, these are presented in the form of music videos that represent the season in which the ident is aired during, which consist of tag-init (summer season), tag-ulan (rainy season), and Pasko (Christmas season). Station IDs in the Philippines runs for three to six minutes depending on the television station. The longest station ID is "Isang Pamilya Tayo Ngayong Pasko", which was used by ABS-CBN as a Christmas ID in 2016, lasting for twelve minutes and 42 seconds. However, ABS-CBN, alongside some networks (i.e. UNTV, RPN, IBC, and PTV), also releases CGI-animated station IDs, not yearly but sporadically.

Station identification in Australia is unlimited to the designated common or on-air name of the station or network affiliation, both for radio and television.

A radio station may have call letters related to its town or district name, and the company name; for example, Charters Towers, Queensland station 4CHT and Ceduna Community Radio Inc's 5CCR in Ceduna, South Australia. The station may have a name-callsign completely different from its licensed callsign, such as Wollongong, New South Wales station 2UUL, which is branded on-air as "Wave FM".
