Abstract: A method and apparatus for transmitting a notification about broadcasting services in a broadcasting system are provided. A method of a network entity includes detecting a notification event about a broadcasting service, the notification event including a change of a service guide of the broadcasting service; generating a notification message about the notification event; determining which channel is used for a transmission of the notification message; and transmitting the notification message to a terminal or a group of terminals over the determined channel. The channel used for the transmission of the notification message is determined based on whether the notification message is transmitted over a broadcast channel of a broadcast network or over an interaction channel of an interaction network. The service guide is generated based on service guide related information provided by a service provider of the broadcasting service.
