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.
Claims7
A receiving method for receiving L1 signaling, the receiving method comprising:
- receiving a signal from a transmitting apparatus;
- demodulating the signal to generate values;
- inserting predetermined values;
- decoding values comprising the generated values and the inserted values based on a first code to generate bits;
- and
- decoding the generated bits based on a second code to generate one of a plurality of segmented blocks;
- wherein the L1 signaling is obtained by combining the plurality of segmented blocks,
- wherein a length of each of the plurality of segmented blocks is determined based on a segmentation value,
- wherein a number of the predetermined values is determined based on a length of zero padding bits and a length of punctured parity bits, and
- wherein the segmentation value is determined based on the first code, a zero padding parameter and a puncturing parameter.
A signal generation and transmitting method comprising.
- segmenting input bits into a plurality of segmented blocks based on a segmentation value, if a size of the input bits is greater than the segmentation value;
- filling information bits with bits and one or more zero padding bits, if a size of the bits is less than a size of the information bits, the bits comprising bits of a segmented block among the plurality of segmented blocks;
- encoding the information bits to generate parity bits based on a code;
- interleaving the generated parity bits;
- puncturing one or more parity bits among the interleaved parity bits;
- removing the one or more zero padding bits from the information bits;
- mapping the bits and remaining parity bits after the puncturing to constellation points;
- and
- transmitting a signal which is generated based on the constellation points,
- wherein the segmentation value is based on the code, a zero padding parameter and a puncturing parameter.
