DIGITAL BROADCASTING RECEPTION APPARATUS AND ROBUST STREAM DECODING METHOD THEREOF

摘要

A digital broadcasting transmission apparatus and robust stream coding method thereof. The digital broadcasting transmission apparatus includes a robust processor that codes a robust stream of a dual transport stream where a normal stream and the robust stream are combined. The robust processor includes a demultiplexer (DE-MUX) that separates the normal stream and the robust stream from the dual transport stream; a robust encoder that appends a parity to the separated robust stream; a robust interleaver that interleaves the robust stream having the appended parity; and a MUX that combines the interleaved robust stream and the separated normal stream. Accordingly, a receiver of a simple structure can be provided.
