PURPOSE: A PoC(Push-to-talk over Cellular) box provided from a PoC system and a media data processing method thereof are provided to transmit in a real time media data requested from a PoC client who does not participate in a session. CONSTITUTION: A data converting unit(64) converts media data received from a PoC server into stream data. A session information generating unit(66) generates session control information for the converted stream data. A data storage unit(68) stores the converted stream data and the session control information. A second control unit(74) determines whether the received media data are transmission data of a streaming type or not. The second control unit controls the data converting unit in order to convert the media data to the stream data.
