Abstract: Provided are transmission and reception apparatuses and methods used in a conditional access system that limitedly allows access to a terrestrial digital multimedia broadcasting (T-DMB) service. The transmission apparatus selects a single service component from a transmission frame which includes a main service channel (MSC) including sub-channels including one or more service components and a fast information channel (FIC) which transmits control information regarding the main service channel to insert an entitlement management message (EMM) that is used to grant or update the entitlement on the DMB service to the selected single service component, and provides location information regarding the selected single service component to the fast information channel.
