ABSTRACT:
An apparatus and method to generate a dual transport stream. The apparatus includes an eraser encoder to receive a turbo stream and to eraser-encode the turbo stream, a duplicator to provide a parity insertion region for the eraser-encoded turbo stream, and a multiplexer to receive a normal stream and to multiplex the turbo stream processed by the duplicator and the normal stream to generate the dual transport stream. The duplicator provides the parity insertion region using a ½-rate conversion method or ¼-rate conversion method. Only the turbo stream is detected prior to the transmission of the dual transport stream, and the parity is inserted into the parity insertion region, so that the turbo stream can be robustly processed.
