Disclosed is a system and method for transmitting/receiving an encrypted Electronic Service Guide (ESG) in a mobile Digital Video Broadcasting-Handheld (DVB-H) Convergence of Broadcast and Mobile Service (CBMS) system. When a terminal performs roaming from a home network to a visited network, the terminal receives an ESG from a neighboring network and determines whether to perform user roaming or to perform service roaming according to the received ESG. In this case, the visited network provides the terminal either with an encrypted ESG and a key for the encrypted ESG, or with non-encrypted ESG through a dedicated channel, so that it is possible to provide the ESG only to specified terminals.
