A transmission system to transmit a transport stream (TS) having normal data and additional data, the transmission system including: a stream constructor to generate a TS, and a multiplexer (MUX) to insert information representing the characteristics of additional data in the TS. Therefore, it is possible for a reception system to use the additional data efficiently.

Digital transmission and reception devices for transmitting and receiving streams, and processing methods thereof

A transmission stream (TS) generating apparatus includes an adaptor which receives general data and generates a stream having a plurality of packets, and which provides adaptive field in some of the plurality of packets, and an inserter which inserts additional data into all the payload areas of some of the plurality of packets that are not provided with the adaptive fields. Because additional data is transmitted, without requiring adaptive field header in certain packet, a data transmission rate is increased.

Transmission stream generating device for generating transmission stream which additional data is stuffed in a payload area of a packet, digital broadcast transmitting/receiving device for transmitting/receiving the transmission stream, and methods thereof

A digital broadcasting receiving system and method, where the digital broadcasting receiving system includes: a demodulator receiving and demodulating a dual transmission stream including a turbo stream and a normal stream; an equalizer equalizing the demodulated dual transmission stream; a first processor restoring normal stream data from the equalized dual transmission stream; and a second processor restoring turbo stream data from the equalized dual transmission stream and eraser decoding the turbo stream data. Thus, the reception sensitivity of a transmission stream including a turbo stream can be improved.

Digital broadcasting receiving system and method

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.

Digital broadcast transmitter/receiver having an improved receiving performance and signal processing method thereof

A digital broadcasting system and method, where the digital broadcasting system includes: a transmission stream generator multiplexing a normal stream and a turbo stream to generate a dual transmission stream; a transmitter inserting an supplementary reference signal (SRS) into the dual transmission stream, processing the turbo stream to reconstitute the dual transmission stream, and outputting the reconstituted dual transmission stream; and a receiver receiving the reconstituted dual transmission stream, separately turbo decoding the turbo stream, inserting the turbo decode turbo stream into the dual transmission stream, and decoding the dual transmission stream into which the turbo decoded turbo stream has been inserted, to restore normal stream data and turbo stream data. Thus, reception sensitivity of a digital broadcasting signal can be efficiently improved.

Digital broadcasting system and method

A method of processing a digital broadcasting signal includes generating a transport stream including a plurality of transport packets; selecting one of the transport packets as a starting packet to be mapped into a first data segment of an encoded data frame; and constructing deterministic data frames in the transport stream beginning with the starting packet; wherein at least one of the 52 transport packets does not have an adaptation field; wherein all remaining ones of the 52 transport packets do have an adaptation field; and wherein the at least one transport packet that does not have an adaptation field is provided at a fixed location in each of the slices.

Method of and apparatus for transmitting digital broadcasting signal in advanced-VSB (A-VSB) system in which transport packet without adaptation field is provided at fixed location in data field slices

An apparatus for processing streams includes a trellis encoding unit which changes a part of streams with parities, an RS re-encoding unit which corrects at least one of parity part and data part of the streams, and generates new codewords to match the changed part of the streams, and a multiplexer which re-constructs the streams with the generated codewords.

Apparatus for processing streams and method thereof

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.

Trellis encoder for encoding dual transmission stream

A digital broadcasting transmission system processes dual transport stream (TS) including multi turbo streams. The digital broadcasting transmission system includes a turbo processor to detect a turbo stream from a dual transport stream (TS) which includes a multiplexed normal stream and a turbo stream, encoding the detected turbo stream and stuffing the encoded turbo stream into the dual TS; and a transmitter to trellis-encode the processed dual TS, and to output the resultant stream, wherein the turbo processor encodes the turbo stream using a plurality of turbo processors. Accordingly, a plurality of turbo streams may be processed in parallel.
