Abstract
A method, a communications system and a receiving device are for billing of access-controlled programs and/or data which are broadcast by a broadcast transmitter unidirectionally and encrypted, and are received by at least one receiving device. A monetary value is stored in a data memory of the receiving device. The costs for access to the access-controlled programs and/or data are determined in the receiving device based on received cost data, and decryption of the access-controlled programs and/or data in the receiving device is prevented if the determined costs are greater than the stored monetary value. Billing records are generated in the receiving device for the allocation of credit items to the vendors of the access-controlled programs and/or data, and are transmitted to a billing center via various data channels.
