An object of the present invention is to reduce the switching time from the reception channel to another reception channel. In fact, this reduction will be in particular due to identify the number of different rights stored in the security module of the multimedia unit or decoder size. When the user selects one service from among the services offered by the EPG, the access control module to search the stored service information table, and extracts the access conditions associated with this service. This access condition allows to determine the index in the authorization table stored in the access control module of the access rights that meet the condition. Access control module transmits the thus determined, with the index alone or a control message to the security module. The index is to allow the security module to quickly find the authority, the authority will subsequently compared by the access conditions contained in the security module decrypts the message after control of the latter.
