    摘要： A digital broadcast transmitting/receiving system, and a signal processing method thereof, includes a randomizer for randomizing a transport stream into a specified position of which stuff bytes are inserted, a stuff-byte exchanger for replacing the stuff bytes included in data output from the randomizer with specified known data, an RS encoder for performing an RS-encoding of data output from the stuff-byte exchanger, an interleaver for interleaving data output from the RS encoder, a trellis encoder for performing a trellis encoding of data output from the interleaver, an RS parity generator for generating a parity by performing an RS encoding of data output from the RS encoder, and outputting the generated parity to the trellis encoder, and a modulator/RF converter for modulating data output from the trellis encoder and performing an RF up-converting of the modulated data. The digital broadcast receiving performance can be improved even in an inferior multi-path channel by detecting the known data from the received signal and using the known data for synchronization and equalization in a digital broadcast receiver.

    摘要： A method of resetting a trellis-coded modulation (TCM) encoder to a known state, the TCM encoder including a reset input that resets the TCM encoder to the known state when held at a reset level for a plurality of symbol clock cycles, the method including identifying an event to occur in the future that requires the TCM encoder to be reset to the known state; and holding the reset input of the TCM encoder at the reset level beginning the plurality of clock symbol cycles before a time the event will occur so that the TCM encoder will be reset to the known state immediately before the event occurs.

    摘要： A trellis encoder for trellis encoding a dual transmission stream. A first multiplexer selectively outputs one of a predetermined first bit of the dual transmission stream and a value stored in a first memory according to an external control signal. A first adder adds the value output from the first multiplexer to the value stored in the first memory, outputs the added value, and stores the added value in the first memory. A second multiplexer selectively outputs one of a predetermined second bit of the dual transmission stream and a value stored in a second memory according to the external control signal. A second adder adds the value output from the second multiplexer to the value stored in the second memory and stores the added value in a third memory. Thus, an initialization is effectively performed before trellis encoding is performed.

    摘要： An outer encoder includes a bit detector that receives a turbo stream provided with a parity insertion region and that detects data bits from the turbo stream, an encoder that convolution-encodes the detected data bits, and a bit inserter that inserts an encoded value outputted from the encoder into the parity insertion region in the turbo stream. The encoder includes a first register; a second register, in which when a bit value is stored in the first register, a stored value pre-stored in the first register is shifted and stored; a third register, in which when a bit value is stored in the second register, a stored value pre-stored in the second register is shifted and stored; a first adder adding the input bit value, the stored value pre-stored in the first register, and the stored value pre-stored in the third register, and storing the resultant value of addition in the first register, if a specified bit is inputted; and a second adder adding the input bit value, the stored value pre-stored in the first register, and the stored value pre-stored in the second register to output the resultant value of addition. Accordingly, only the turbo stream in the dual transport stream is robustly processed.
