A transmitter is provided. The transmitter includes: a Low Density Parity Check (LDPC) encoder which encodes input bits including outer encoded bits to generate an LDPC codeword including the input bits and parity bits to be transmitted to a receiver in a current frame; a puncturer which punctures a part of the parity bits which is not transmitted in the current frame; and an additional parity generator which selects at least a part of the parity bits to generate additional parity bits transmitted to the receiver in a previous frame of the current frame, wherein a number of the additional parity bits is determined based on a number of the outer encoded bits and a number of the parity bits left after the puncturing.
A television (TV) broadcast signal transmitting apparatus for transmitting layer 1 (L1) signaling information and TV broadcast data, the TV broadcast signal transmitting apparatus being operable in a mode among a plurality of modes, the transmitting apparatus comprising:

1. Field
Apparatuses and methods consistent with exemplary embodiments of the inventive concept relate to a transmitter and a method of generating an additional parity for signal transmission.
2. Description of the Related Art
The above and/or other aspects of the exemplary embodiments will be described herein with reference to the accompanying drawings, in which:
FIG. 1 is a block diagram for describing a configuration of a transmitter, according to an exemplary embodiment;
FIGS. 2 and 3 are diagrams for describing a parity check matrix, according to exemplary embodiments;
Hereinafter, the exemplary embodiments will be described in more detail with reference to accompanying drawings.
FIG. 1 is a block diagram illustrating a configuration of a transmitter according to an exemplary embodiment. Referring to FIG. 1, a transmitter 100 includes a Low Density Parity Check (LDPC) encoder 110, a repeater 120, a puncturer 130, and an additional parity generator 140.
The LDPC encoder 110 may encode input bits of a service which may include various data. In other words, the LDPC encoder 110 may perform LDPC encoding on the input bits to generate parity bits, that is, LDPC parity bits.
