APPARATUS AND METHOD FOR TRANSMITTING AND RECEIVING MULTIMEDIA

摘要

PURPOSE: An apparatus and a method for transmitting and receiving multimedia are provided to enhance error resilience by unevenly performing error protection for source packets. CONSTITUTION: The first error protection layer(330) and the second error protection layer(340) are inserted between a source packetizer including a video packetizer(310) and an audio packetizer(320) and an RTP(Real-time Transport Protocol) layer(350). The first error protection layer(330) and the second error protection layer(340) generate an FEC(Forward Error Correction) packet as a result of the performance of an uneven error protection for one or more video or audio packets packetized in the video packetizer(310) and the audio packetizer(320).
