The present invention relates to a system and method for outputting contents in a CPNS environment, comprising: a user terminal for searching for a contents playback terminal including a wireless communication unit supporting CPNS, sharing the contents with the contents playback terminal by connection to the user terminal through a short-range communication network, decoding corresponding contents in response to a contents playback request received from the user terminal, converting the corresponding contents into frequency modulation (“FM”) data, transmitting the converted FM data to a contents output device for demodulating the FM data received from the contents playback terminal and outputting the demodulated FM data in real-time through a contents output device.
