Abstract: Provided are a method and a device for transmitting and receiving multimedia data. The present invention comprises: receiving of multimedia data and confirming of loss data; determining, with respect to the degree of the loss of the received data, of whether or not the lost data can be recovered by means of application layer forward error correction (AL-FEC); if data recovery by means of the AL-FEC is not possible, making of an automatic retransmission request (ARQ) with respect to the lost data; and receiving of data retransmitted with respect to the ARQ and recovering of the lost data.
