Abstract
A method, apparatus, and system for transmitting and receiving data in a digital broadcasting system based on Orthogonal Frequency Division Multiplexing (OFDM) are provided. A transmitter frames input bit information in a predetermined bit unit, maps the framed input bit information to a transmitter identification indicator (TII) using a predefined number of orthogonal sets, and modulates the TII to an OFDM symbol to transmit the OFDM symbol. A receiver demodulates an OFDM symbol, detects a TII symbol from a predefined orthogonal signal set, demaps predetermined bits from the TII, and concatenates the demapped bits in a predetermined period unit to output bit information. Therefore, the TII can be stably received as a conditional access signal for distinguishing a broadcasting network and a relay network in the digital broadcasting system.
