    Abstract: 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.

A digital broadcasting transmitter according to the present invention includes a data pre-processor which processed robust data and generates robust data packet of predetermined format, a TS stream generator which combines robust data packet with a normal data packet to generate a TS stream of a predetermined format, a randomizer which randomizes the TS stream output from the TS stream generator, a convolution encoder which performs convolution encoding with respect to the robust data of the data output from the randomizer, and a RS encoder which performs RS encoding with respect to the data output from the convolution g encoder. Accordingly, digital broadcasting receiving performance can be improved in a poor multipath channel, while maintaining compatibility with existing transmission/reception system.

    Abstract: A digital broadcasting transmission and/or reception system having an improved reception performance and a signal-processing method thereof. A digital broadcasting transmitter comprises a randomizer to input and randomize data streams including a plurality of segments having at least one segment having one or more null packets, a null packet exchanger to create known data having a predetermined pattern and to replace the null packets at positions of the segments having the null packets of the randomized data streams to insert the known data, an encoder to encode the data streams to which the known data is inserted, and a modulation/RF unit to modulate, RF-modulate, and transmit the encoded data streams. A digital broadcasting receiver detects the known data from a signal received from the digital broadcasting transmitter and uses the detected known data for synchronization and equalization, so that a digital broadcasting reception performance of the digital broadcasting receiver can be improved at poor multipath channels.
