DIGITAL BROADCASTING SYSTEM AND METHOD THEREOF

摘要

A digital broadcasting system and a method thereof are provided to produce the dual transmission stream including the normal stream and the turbo stream, and to transmit/receive the produced dual transmission stream. A transmission stream generating device(100) multiplexes the normal stream and the turbo stream processed robustly compared to the normal stream, and then produces the dual transmission stream. A transmission device(200) inserts an addition reference signal into the dual transmission stream, reconstructs the dual transmission stream by performing the signal process relating to the turbo stream, and outputs the reconstructed dual transmission stream. A receiving device(300) receives the reconstructed dual transmission stream, decodes the normal stream and the turbo stream, respectively and restores the normal stream and the turbo stream. The transmission stream generating device includes a reed-solomon encoder for receiving the turbo stream from the outside and for performing the reed-solomon encoding relating to the turbo stream.
