    摘要： A transport stream (TS) generating apparatus, a transmitting apparatus, a receiving apparatus, a digital broadcast system having the above, and a method thereof are provided. The digital broadcast system includes a transport stream (TS) generating apparatus which generates a multi transport stream (TS) by multiplexing a normal stream and a turbo stream having a variable coding rate, a transmitting apparatus which re-constructs the multi TS by processing the turbo stream, and transmits the re-constructed multi TS, and a receiving apparatus which receives the re-constructed multi TS, and decodes the normal stream and the turbo stream respectively, to recover normal data and turbo data. Accordingly, a multi TS, which includes normal stream and a turbo stream of various coding rates, can be transmitted and received efficiently.

    摘要： 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.
