    Abstract: A method and an apparatus are provided for transmitting and receiving signaling information in a digital broadcasting system. The method includes encoding first signaling information for a physical layer to generate a first coded block; encoding second signaling information to generate a second coded block; and transmitting a frame including the first coded block, the second coded block, and at least one physical layer pipe (PLP) data. The first signaling information has a fixed number of bits, and the second signaling information has a variable number of bits. The first signaling information includes information indicating a forward error correction (FEC) type of the second signaling information for receiving the second information, and the second signaling information includes information indicating a modulation scheme used for a related PLP data.

    Abstract: A method for bit-interleaving coded bits for Incremental Redundancy (IR) transmission in a transmission apparatus of a digital video broadcasting system is provided. The method includes sequentially writing the coded bits in a memory area having a predetermined size, reading the coded bits written in the memory area based on a reading order that is differently set for each of normal transmission and at least one IR transmission, and outputting one coded systematic bit stream interleaved for the normal transmission and at least one coded parity bit stream interleaved for at least one IR transmission.

    Abstract: A method for transmitting a signal in broadcasting and communication systems is provided. The method includes dividing source data into two or more streams and respectively coding the two or more streams through coders, selecting two or more symbols from among coded codeword symbols, mapping the selected two or more symbols to one signal constellation for modulation, and transmitting a modulated signal, in which the codeword symbols include one or more non-binary codewords, and a product of orders of finite fields on which the codeword symbols are defined is equal to an order of the signal constellation.

    Abstract: A method and apparatus are provided for recovering data efficiently even when data loss has occurred over a channel or network. The packet transmission method includes arranging a first transmission packet in a source symbol in a first region of a source block; arranging a second transmission packet in a space starting with an empty space of a last source symbol where the first transmission packet is arranged, remaining after arranging the first transmission packet; arranging information related to the second transmission packet in a second region of the source block; performing Forward Error Correction (FEC) encoding on the source block; and transmitting the encoded source block.
