1. A transmitting apparatus comprising:
a zero padder configured to fill information bits with input bits and one or more zero padding bits, if a number of the input bits is less than a number of the information bits, wherein the input bits are based on signaling information related to TV broadcast data;
an encoder configured to encode the information bits based on a low density parity check (LDPC) code to generate parity bits, a code rate of the LDPC code being 6/15 and a code length of the LDPC code being 16200 bits;
an interleaver configured to interleave the parity bits;
a zero remover configured to remove the one or more zero padding bits among the information bits;
a constellation mapper configured to map the input bits and the interleaved parity bits onto constellation points for quadrature phase shift keying (QPSK); and
a transmitter configured to transmit a TV broadcast signal which is generated based on the constellation points,
wherein the zero padder is configured to fill the information bits by dividing the information bits into a plurality of bit groups and padding the one or more zero padding bits to at least one bit group among the plurality of bit groups based on an order,
wherein the order is represented below:
 
 
 πs(j) (0 ≤ j < Ninfo_group)
j 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17
 
πs(j) 0 12 15 13 2 5 7 9 8 6 16 10 14 1 17 11 4 3,
 
where πs(j) represents an index of a bit group padded to which the one or more zero padding bits are in a j-th order among the plurality of bit groups, and Ninfo_group represents a number of the plurality of bit groups.
