Abstract

See full text

An arrangement, for verifying a playing authorization for an encrypted information signal reproduced by a reproducing device and for supplying a decrypted information signal when a playing authorization is available, includes a verification device for verifying a playing authorization for a reproduced encrypted information signal, and a decryption circuit for decrypting a reproduced encrypted information signal when a playing authorization is available. The arrangement further includes an interrogation device for independently requesting a playing authorization. The interrogation device includes a communication circuit which, in the absence of a playing authorization for a reproduced encrypted information signal, sets up a data link and supplies playing authorization request information to a playing authorization allocation device via the data link, and receives a playing authorization for the reproduced encrypted information signal from the playing authorization allocation device.
