Described embodiments provide user equipment for converting a first type data stream to a second type data stream. The user equipment may include a request message transmitting unit, a first stream receiving unit, a converting unit, and a reproducing unit. The request message transmitting unit may transmit a content request message to a streaming server in order to request a predetermined content stored in the streaming server. The first stream receiving unit may receive, from the streaming server, a first type data stream created from the requested content based on a first protocol in response to the content request message. The converting unit may convert the received first type data stream to a second type data stream. The second type data stream may be a data stream generated based on a second protocol. The reproducing unit may reproduce the requested content based on the second type data stream.
