Method and device for transmitting decryption codes of freely transmitted, encrypted program contents to clearly identifiable receivers

摘要

The invention relates to a method and to a device for transmitting decryption codes for freely transmitted, encrypted program contents, enabling decryption codes to be transmitted in a more simple manner and enabling a connection or a user to be established via a user network, also enabling the reception of a telephone call, identification of the network termination element, especially the telephone number, and transmission of the decryption code for a program content. Billing data can be automatically established using the network termination element/the telephone number and information on the requested program content. Additionally or alternatively, examination is possible if a registered right of access for the decryption code exists for the network termination element/telephone number, whereby transmission occurs exclusively for the existing right of access. The invention also relates to a system for decrypting freely transmitted, encrypted program contents.

主权项

1. A method for transmitting decryption codes for freely transmitted encrypted program contents and for automatically establishing billing data for the program contents, comprising:
a customer receiving encrypted program content from a broadcast source; connecting the customer to a service provider via the customer's subscriber network, by placing a telephone call; determining a network terminating unit of the existing connection to the service provider, and a calling party number of the customer and a called number of the service provider; integrating information about the identified calling party number into a decryption code for a program content; transmitting the decryption code for a program content to the customer; and establishing billing data using the network terminating unit, in particular the calling party number, the called number of the service provider, and information about the requested program content; wherein the program content data is transmitted through a different medium than the decryption code and wherein the decryption code is transmitted through a telephone line.
