Abstract: An apparatus and a method for outputting contents where an Output Protection Level (OPL) has been set to an extension device in an electronic device are provided. The apparatus includes a secure processor for decrypting and decoding contents where a right to use the contents has been set using a secure Operating System (OS). When receiving an external output request for contents whose external output is not allowed, the secure processor stops generating of decoded data transmitted to an extension device.
