Transmitter and system for transmitting/receiving digital broadcasting stream and method thereof
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.
1. A digital broadcasting transmission apparatus, comprising:
at least one outer encoder to outer encode at least one of additional data streams according to 1/2 rate or 1/4 rate;
a re-arrangement unit to rearrange the at least one of encoded additional data streams; and
a stuffer to insert the at least one of rearranged additional data streams into a normal data stream.
2. The digital broadcasting transmission apparatus of claim 1 , wherein the re-arrangement unit comprises at least one of re-arrangers to be connected to the at least one of encoders.
3. The digital broadcasting transmission apparatus of claim 1 , wherein the re-arrangement unit comprises a re-arranger to combine and rearrange the at least one of additional data streams output by the plurality of respective encoders.
4. The digital broadcasting transmission apparatus of claim 1 , further comprising:
a plurality of de-multiplexers to detect the at least one of additional data streams and transmit the at least one of additional data streams to the at least one of encoders.
5. A transmission method of a digital broadcasting transmission apparatus, the method comprising:
by at least one outer encoder, outer encoding at least one of additional data streams according to 1/2 rate or 1/4 rate;
rearranging the at least one of encoded additional data streams; and
inserting the at least one of rearranged additional data streams into a normal data stream.
6. The transmission method of claim 5 , wherein the re-arranging operation comprises rearranging the at least one of respective additional data streams output by the at least one of respective encoders.
7. The transmission method of claim 5 , wherein the re-arranging operation comprises combining and rearranging the at least one of respective additional data streams output by the at least one of respective encoders.
8. The transmission method of claim 5 , further comprising:
detecting the at least one of additional data streams and transmitting the at least one of respective additional data streams to the at least one of respective encoders.
