A system for transmitting a transport stream including a robust stream is provided. The transmitting system includes an adaptor for, when receiving a first stream, making a space in the first stream to insert a second stream; a Reed-Solomon (RS) encoder for RS-encoding the input second stream; a Cyclic Redundancy Check (CRC) processor for converting the RS-encoded second stream to a stream comprising an added CRC bit sequence; and a stuffer for inserting the stream to the space in the first stream and outputting a transport stream. Hence, the robust stream can be efficiently transmitted.

The method for transporting a digital broadcast stream includes: receiving a transport stream, including mobile broadcast data that is placed in at least a part of a normal data area allocated to normal data and signaling data that includes an FIC chunk header with a variable length; decoding the signaling data; and decoding the mobile data using the decoded signaling data.

A digital broadcasting transmitter includes a known data inserting unit which inserts a known data to a stream, and a trellis encoding unit which encodes the stream sequentially using a plurality of trellis encoders, wherein the known data inserting unit inserts the known data to the specific location of the stream, so that the known data may be trellis encoded by at least one specific trellis encoder.

A device for processing streams is disclosed. The device includes a stream arranging unit which stacks and rearranges a stream, and a dummy inserting unit which inserts a dummy into the rearranged stream. The device may further include a convolutional interleaver which interleaves the stream with a dummy or an RS encoder and a CRC encoder.

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.

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.
