Abstract
A transmitter and receiver of a broadcasting signal and a method of processing the broadcasting signal are provided. The transmitter includes: a segmenter configured to segment an L1 signaling of a frame into a plurality of segmented L1 signalings such that each of the segmented L1 signalings has bits a number of which is equal to or smaller than a predetermined number; and an encoder configured to perform a Bose, Chaudhuri, Hocquenghem (BCH) and a low density parity check (LDPC) encoding, or the LDPC encoding without the BCH encoding, with respect to the segmented L1 signalings.
Claims6
A signal generation and transmitting apparatus comprising:
- a segmenter configured to segment input bits into a plurality of segmented blocks according to a segmentation value, if a size of the input bits is greater that the segmentation value;
- a first encoder configured to first encode the plurality of segmented blocks based on a first code to generate codewords respectively, a codeword comprising bits of a segmented block and first parity bits which are generated based on the first code;
- a zero padder configured to fill a bit space of a predetermined size with bits of the codeword and one or more zero padding bits, if a size of the codeword is less than the predetermined size;
- a second encoder configured to second encode bits included in the bit space to generate second parity bits based on a second code
- a puncturer configured to puncture, from the second parity bits, one or more parity bits;
- a mapper configured to map remaining parity bits after the puncturing onto constellation points;
- and
- a transmitter configured to transmit a signal which is generated based on the constellation points,
- wherein the segmentation value is based on the second code, a zero padding parameter and a puncturing parameter.
A signal generation and transmitting method of a signal generation and transmitting apparatus, the method comprising:
- segmenting input bits into a plurality of segmented blocks according to a segmentation value if a size of the input bits is greater than the segmentation value;
- first encoding the plurality of segmented blocks based on a first code to generate codewords respectively, a codeword comprising bits of a segmented block and first parity bits which are generated based on the first code filling a bit space of a predetermined size with bits of the codeword and one or more zero padding bits, if a size of the codeword is less than the predetermined size;
- second encoding bits included in the bit space to generate second parity bits based on a second code;
- puncturing, from the second parity bits, one or more parity bits;
- mapping remaining parity bits after puncturing onto constellation points;
- and
- transmitting a signal which is generated based on the constellation points
- wherein the segmentation value is based on the second code, a zero padding parameter and a puncturing parameter.
