Abstract
A special instruction for not encoding a content is incorporated into access authorization data contained in the received signal, so that within a unified system for transmitting and receiving of encoded or non-encoded sound and/or picture contents, it is possible to meet the requirement of public broadcasting and “free-to-air” program providers for a non-encoded processing and/or display and/or storage of freely accessible contents for the end user. The instruction signalizes that the sound and/or picture contents, once received, must be available in the non-encoded form to the end user. The access authorization data remain added to the sound and/or picture contents, even in cases of a cascading, encoded retransmission, or remains logically linked thereto by suitable means, even if transmitted physically separate along with the picture and/or sound contents. During the processing and/or display and/or storage of the picture and/or sound contents retransmitted in the encoded form, the special instruction triggers a decoding of the picture and/or sound contents, at least at the end of the retransmission cascade.
