An adaptive decoder generates a program representative datastream, in selectable, encrypted or decrypted form. A method for adaptively processing input encrypted program data with an associated encryption code provides either an encrypted or a decrypted program output. In an encrypted mode, encrypted program data and an associated encryption code is exported to an output port. In a decrypted mode, input encrypted program data is decrypted using an encryption key derived from the encryption code to provide decrypted program data. The decrypted program data is exported to the output port. Non-encrypted program data is exported to an output port in a selectable non-encrypted mode.
In a video decoder, a method for adaptively processing input encrypted program data with an associated encryption code to provide either an encrypted or a decrypted program output, comprising the steps of:
In a video decoder, a method for adaptively processing a plurality of programs including encrypted program data with an associated encryption code and non-encrypted program data, to provide either encrypted, non-encrypted or decrypted output program data, comprising the steps of:
