Abstract
A method for processing a dual transport stream (TS) which is multiplexed from a normal stream and a turbo stream is provided for a digital broadcasting transmission/reception system. The digital broadcasting signal processing method includes encoding a dual transport stream (TS) which is multiplexed from a normal steam and a turbo stream; interleaving the encoded dual transport stream (TS); turbo-processing by detecting the turbo stream from the interleaved dual transport stream (TS), encoding the detected turbo stream, stuffing the encoded turbo stream into the dual transport stream (TS), and compensating a parity corresponding to the encoded turbo stream; and trellis-encoding the turbo-processed dual transport stream (TS). Accordingly, the digital broadcasting reception performance can be improved in diverse environments.
