1. A transmitting method of a transmitting apparatus being operable in a mode from among a plurality of modes, the transmitting method comprising:
filling information bits with input bits and one or more zero padding bits, if a size of the input bits is less than a size of the information bits;
encoding the information bits to generate parity bits based on a low density parity check (LDPC) code;
appending one or more parity bits of the generated parity bits between the information bits and the generated parity bits in a predetermined mode from among the plurality of modes;
puncturing one or more parity bits from the generated parity bits;
calculating a number of additional parity bits based on a number of the generated parity bits;
selecting the additional parity bits based on the calculated number;
generating a broadcast signal based on a first frame including the additional parity bits and a second frame including remaining parity bits of the generated parity bits after the puncturing and the appended parity bits; and
transmitting the broadcast signal,
wherein the first frame is transmitted prior to the second frame.
