ABSTRACT:
A decoder excludes an encryption code or key from decrypted or non-decrypted program output data. Decrypted program representative data is generated from an input datastream containing encrypted program data and an associated encryption code. The encrypted program data is decrypted using the encryption to provide decrypted program data. An output datastream is formed containing the decrypted program data but excluding the encryption code. The encryption code may be excluded by submitting non-encryption code data for the encryption code. The output datastream may also contain ancillary date formed to support decoding of the decrypted program data.
