APPARATUS AND METHOD FOR TRANSMITTING AND RECEIVING PACKET IN COMMUNICATION SYSTEM

摘要

PURPOSE: An apparatus and method for transmitting and receiving a packet in a communication system are provided to transmit signaled information to a receiver by signaling FEC configuration information including application information for a first FEC(Forward Error Correction) and a second FEC or other encoding configuration information. CONSTITUTION: A FEC control packet(300) comprises a FEC control payload for encoding configuration information and a header therefor. The FEC control information is included when a transmitter report using SDP(Session Description Protocol) is transmitted to a receiver. The FEC control information is included in the FEC control payload. The FEC control information comprises the FEC configuration information included in an encoding structure field in case of out-band signaling, a first FEC Encoding Configuration(320), and a second FEC Encoding Configuration(330).
