Barker channel

A barker channel is a form of digital signage, operating in the form of a television channel that is entirely composed of sales promotion and advertising, usually marketing various features of the service carrying the channel. The name is derived from the circus barker, who stood outside a circus and shouted to passers-by to encourage them to enter to view the entertainment being provided by the attraction.

The systems are similar to character generators (CG), incorporating features such as motion graphics and have the ability to play video clips controlled by broadcast automation systems.

Several barker channels exist on digital cable systems, and especially on direct broadcast satellite systems such as DirecTV. On interactive television systems, these also allow for ordering of pay-per-view program selections or other pay television services. Prior to its 2008 purchase by Lions Gate Entertainment and subsequent conversion into a general entertainment channel (eventually leading to its rebranding as Pop in January 2015), the TV Guide Network – along with featuring listings for upcoming programs – functioned essentially as a barker channel with film and program descriptions. During its years as Prevue Guide/Channel, it served as a barker channel outright, incorporating video program promotions and short-form film trailers at the top half of the screen.
