Method for a receiving device, which is configured to receive and to output media content and media content transmitted in encrypted form, wherein a media content is received via a receiving channel and at least one identifier is allocated to the receiving channel, wherein several receiving channels are configured, wherein at least one encrypted receiving channel is configured to receive media content transmitted in encrypted form, wherein the media content transmitted in encrypted form was encrypted using a primary algorithm, wherein at least one module is configured to decrypt at least one media content transmitted in encrypted form by means of one or more secondary algorithms, wherein by means of the method a module is allocated to an encrypted receiving channel and this encrypted receiving channel is coupled with the allocated module for decrypting a media content transmitted in encrypted form by means of the allocated module, wherein a properly allocated and coupled module provides decrypted media content by resolving the encryption generated with the primary algorithm by means of the secondary algorithm, wherein an incorrectly allocated and coupled module does not provide any decrypted media content, wherein a test procedure is configured to determine whether a module is correctly or incorrectly allocated by providing decrypted media content or not, wherein the test procedure accordingly provides a positive or negative result, respectively, wherein the method uses a memory in such a way that the result of the test procedure is determined per module and is stored in the memory for an identifier of the respective receiving channel, wherein, when allocating an encrypted receiving channel to a module, it is determined on the basis of the at least one identifier of the encrypted receiving channel whether a positive result of the test procedure for this at least one identifier has been determined and stored for more than one module, and if so, the module with the lowest significance is selected for allocation, wherein the lowest significance is determined by means of the memory, wherein the significance of a module is determined by a module-spanning number being subtracted from a module-specific number, wherein the module-specific number is the number of identifiers for which a positive result of the test procedure was determined and stored for the respective module, wherein the module-spanning number is the number of identifiers in an intersecting set for which a positive result of the test procedure was determined and stored for all modules equally. which is configured to receive and to output media content and media content transmitted in encrypted form, wherein a media content is received via a receiving channel and at
