    Abstract: A digital broadcast receiving system includes a known data detector, a carrier recovery unit, and a timing recovery unit. The known data detector may detect known data information inserted and transmitted from a digital broadcast transmitting system and using the known data information to estimate initial frequency offset. The carrier recovery unit may obtain initial synchronization by using the initial frequency offset, and may detect frequency offset from the received data by using the known sequence position indicator so as to perform carrier recovery. The timing recovery unit may detect timing error information from the received signal by using the known sequence position indicator so as to perform timing recovery.

    Abstract: A digital broadcast system including a broadcast receiving system and data processing method are disclosed. In the broadcast receiving system receiving broadcast signals, the broadcast receiving system includes a transmission parameter decoding unit, a known sequence detector, and a burst controller. The transmission parameter decoding unit detects information on a burst of a received signal from broadcast data having main service data and mobile service data multiplexed therein within a field of the received signal and outputs the detected information on the burst. The known sequence detector receives burst information from the transmission parameter decoding unit and uses the received burst information and known data position information included in the received data, so as to output burst control information. The burst controller uses the burst control information to control power supply of the broadcast receiving system.

    Abstract: A DTV transmitting system includes a frame encoder, a randomizer, a block processor, a group formatter, a deinterleaver, and a packet formatter. The frame encoder builds an enhanced data frame and adds parity data into the data frame. The frame encoder further divides the data frame into first and second sub-frames including first and second portions of the parity data, respectively, and permutes a plurality of the first sub-frames and a plurality of the second sub-frames, respectively. The randomizer randomizes enhanced data in the permuted sub-frames, and the block processor codes the randomized data at a rate of 1/N1. The group formatter forms a group of enhanced data having one or more data regions and inserts the 1/N1 coded data into at least one of the data regions. The deinterleaver deinterleaves the group of enhanced data, and the packet formatter formats the deinterleaved data into enhanced data packets.
