1. A method for decoding a Multi-Protocol Encapsulation Forward Error Correction (MPE-FEC) frame in a receiver of a Digital Video Broadcasting (DVB) system, the method comprising the steps of:

  • performing Packet Identifier (PID) filtering on a Transport Stream (TS) packet received via a wireless network to detect a TS packet including section data of a Multi-Protocol Encapsulation (MPE) section or an MPE-FEC section;

    detecting a table ID from header information of the section data to identify the type of the section data;

    performing frame buffering on an IP datagram extracted from the MPE section in a data region of a buffer if the section data is an MPE section;

    performing zero-padding on a remaining portion in the data region if there is a remaining portion in the data region after storage of an IP datagram of the last MPE section;

    performing frame buffering on parity data extracted from the MPE-FEC section if the section data is an MPE-FEC section; and

    performing Reed-Solomon (RS) decoding on the IP datagram using the parity data to output the error-corrected IP datagram.
