Claim 0:
1. A receiving apparatus comprising:
a demodulator configured to demodulate a signal received at the receiving apparatus from a transmitting apparatus to generate values based on a modulation method, the signal carrying broadcasting data;
a block deinterleaver configured to write values of the generated values in a first part of columns, write remaining values of the generated values in a second part of the columns in a writing direction, read the values written in the first part, and read the remaining values written in the second part in a reading direction,
a group deinterleaver configured to split the values read from the first part and the remaining values read from the second part into a plurality of groups, and deinterleave the plurality of groups; and
a decoder configured to decode values of the deinterleaved plurality of groups to output bits, wherein the bits correspond to the broadcasting data,
wherein the first part comprises a part of each of the columns and the second part comprises a remaining part of the each of the columns,
wherein a number of the values written in the first part is determined based on the modulation method and a number of the plurality of groups,
wherein a number of the remaining values written in the second part is determined based on the number of the values written in the first part,
wherein the modulation method is one of quadrature phase shift keying (QPSK), 16-quadrature amplitude modulation (QAM), 64-QAM and 256-QAM, and
wherein the remaining values are written from a first column of the second part after the values are written to a last column of the first part.
