摘要:
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.

An apparatus for processing a transport stream is provided. The apparatus includes a detector which detects data bits in a stream, an encoder which encodes the data bits detected by the detector and generates two encoding values for each data bit, and a stream constructor which constructs a transport stream using the encoding values generated by the encoder. Accordingly, it is possible to encode the data bits into a transport stream having a coding rate of ⅓.

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.

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.

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.
