Packet transmission/reception apparatus and method using forward error correction scheme
First Claim
1. A method for receiving a packet in a device, the method comprising,receiving a forward error correction (FEC) source packet including a source payload and a source payload identifier (ID);
- andreceiving an FEC repair packet corresponding to at least one source payload, the FEC repair packet including a repair payload and a repair payload ID,wherein the source payload ID includes a source payload sequence number that starts from an arbitrary value and is initialized to 0 after reaching a maximum value.

Abstract
A packet transmission/reception apparatus and method is provided. The packet transmission method of the present invention includes acquiring a source payload including partial source symbols from a source block, generating a source packet including the source payload and an identifier (ID) of the source payload, generating a repair packet including a repair payload corresponding to the source payload and an ID of the repair payload, generating a Forward Error Correction (FEC) packet block including the source and repair packets, and transmitting the FEC packet block. The source payload ID includes a source payload sequence number incrementing by 1 per source packet. The packet transmission/reception method of the present invention is advantageous in improving error correction capability and network resource utilization efficiency.
