    Abstract: PURPOSE: An OFDM(Orthogonal Frequency Division Multiplexing) transmitter, a receiver, a receiving module and a transceiving method thereof are provided to proceed synchronization/channel estimation about a received OFDM signal in the OFDM receiver more accurately by inserting Pseudo Noise sequence information with a size of 511 symbol or 1023 symbol into an OFDM symbol in the receiving side. CONSTITUTION: An FEC(Forward Error Correction) coding unit(100) proceeds coding about an input data. An IDFT(Inverse Discrete Fourier Transform)(200) converts the coded data into an OFDM symbol. A PN(Pseudo Noise sequence) insertion unit(400) inserts PN sequence into the OFDM symbol. The PN sequence has at least 511 symbol size. A pulse forming unit(500) proceeds pulse forming filtering about the OFDM symbol. An RF(Radio Frequency) up-conversion part(600) converts changes the OFDM symbol into an RF signal.

    Abstract: PURPOSE: A digital broadcasting receiver having improved receiving performance and a signal processing method thereof are provided to improve the receiving performance by detecting a transmission signal added with known data. CONSTITUTION: A demodulation unit(1510) receives and demodulates a stream including known data. An equalization unit(1520) equalizes the demodulated stream. The stream is transmitted from a digital broadcasting transmitter. The digital broadcasting transmitter includes a RS(Reed-Solomon) encoder. If at least a part of an initialization byte is replaced with a new value, the RS encoder performs RS encoding of the part, replaced with the new value, and corrects parity.

    Abstract: An apparatus and a method for transmitting/receiving a digital broadcast are provided to allow a viewer in a good channel environment to watch a quality digital broadcast by receiving both a main stream and a sub-stream. A layer type encoding unit(110) hierarchically encodes data to output a main stream and a sub-stream. A main stream coding unit(120) generates a parity with respect to the main stream. A stream adding unit(130) adds the parity-generated main stream to the sub-stream. A transmitting unit(160) transmits the main stream-added sub-stream. The stream adding unit adds the coded main stream to an adaptation field of the sub-stream. The stream adding unit adds the coded main stream to a private data region of the sub-stream. An FEC(Forward Error Correction) coding unit(140) performs FEC coding on the main stream-added sub-stream. A modulation unit(150) modulates the coded stream.

    Abstract: A trellis encoder for encoding a dual transport stream is provided to perform initialization in suitable timing and perform the trellis encoding of the transport stream. The first multiplexer(111) selectively outputs one of the first bit in a transport stream and a storing value stored in the first memory(115) according to an external control signal. The first adder(113) adds the output value outputted from the first multiplexer and the storing value stored in the first memory, and stores the added result value in the first memory. The second multiplexer(112) selectively outputs one of the second bit in the transport stream and a storing value stored in the second memory(116) according to the external control signal. The second adder(114) adds the output value of the second multiplexer and the storing value stored in the second memory, and stores the added result value in the third memory(117).
