APPARATUS AND METHOD FOR PROCESSING BIT STREAM OF EMBEDDED CODEC BY PACKET

摘要

An apparatus and a method for processing a bit stream of an embedded codec received by packet are provided to effectively adjust the size of a jitter buffer by using information about packets of a core layer. A packet receiving unit(602) receives a bit stream of an embedded codec, having layers, by a packet unit including the layers. A layer information unit(603) recognizes layer information of the received packet. A bit stream determining unit(607) assembles the bit stream of the received packet according to the recognized layer information to construct a bit stream in its initial transmission. When some packets of a particular layer are not received to the packet receiving unit(602), a bit stream generating unit(608) generates a new bit stream by combining received packets of a layer lower than the packets that have not been received. An embedded decoder(609) decodes the final bit stream.
