Digital broadcasting system and error correction method thereof

摘要

A digital broadcasting system and an error correction method thereof includes: a server to group a predetermined number of multicast packets to obtain Forward Error Correction (FEC) groups for digital broadcast data (MPEG TS) transmission, to create FEC data for each multicast packet using digital broadcast data (MPEG TS) of the multicast packets in the FEC groups, including the FEC data in the multicast packets, and to transmit the resultant multicast packets over a network; and a set-top box to recover digital broadcast data (MPEG TS) pieces of the digital broadcast data (MPEG TS) pieces of multicast packets other than the lost multicast packet in the FEC group to recover the lost multicast packet in response to a multicast packets received over the network being lost.
