摘要： Provided are a method and apparatus for indicating service variation in a Convergence of Broadcasting and Mobile Service (CBMS) system. A network entity aggregates information about a first service that can be provided by a current network and information about a second service of associated another network in order to generate service variation information indicating whether at least one of a language, a subtitle, and a camera angle of the second service is changed when compared to the first service, and transmits the service variation information to a terminal in the current network over a broadcasting network or an interactive network. The terminal can determine whether to receive the second service continuously from the first service from the other network using the service variation information.
