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.

Abstract: A method and a communications system are for billing of access-controlled programs and/or data, which are broadcast unidirectionally and encrypted from a broadcast transmitter and which are received by at least one receiving device. The programs and/or data broadcast encrypted are decrypted in the receiving device for access if received access conditions data for the access-controlled programs and/or data coincide with authorization data for the user. Clearing data from the central unit are thereby transmitted to a clearing module. The clearing data include billing data for the access to the unencrypted access-controlled programs and/or data as well as user data. The central unit makes available to the vendor information relating to the user data, in accordance with the received clearing data, which information is generated by the central unit according to specified conditions on further use.
