APPARATUS AND METHOD FOR TRANSMITTING/RECEIVING PACKET IN BROADCASTING AND COMMUNICATION SYSTEM

摘要

A method for transmitting a packet by a signal transmission apparatus in a broadcasting and communication system is provided. The method includes generating a Forward Error Correction (FEC) packet including an FEC parity packet and an FEC source packet by encoding source payloads using an FEC encoding scheme, and transmitting the FEC packet to a signal reception apparatus, wherein the FEC parity packet is generated using a plurality of Source Sub-Blocks (SSBs) which are generated using specific source payloads selected corresponding to a preset SSB generation scheme from among the source payloads included in a source block, and wherein the FEC source packet is generated using the source payloads.
