    摘要: A digital broadcast transmitting and a method of processing broadcast data in a digital broadcast transmitting system are disclosed. The method includes randomizing mobile service data; RS encoding and CRC encoding the randomized mobile service data to build an RS frame; dividing the built RS frame into L (L>1) number of portions and adding K bytes (K≧0) of dummy data to one of the portions; encoding data in the portions at a code rate of 1/H (H>1); first interleaving the encoded data; mapping the first interleaved data into data groups and adding known data sequences and transmission parameters to each of the data groups, deinterleaving data of the data groups; second interleaving the deinterleaved data; and transmitting a transmission frame including the second interleaved data.

    摘要: A receiving system and a data processing method for receiving and processing mobile service data are disclosed. The receiving system comprises a demodulating unit, a block decoder, a controller, and an RS frame decoder. The demodulating unit receives a broadcast signal including mobile service data and main service data and converts the received broadcast signal to a baseband broadcast signal. The mobile service data configure at least one of a primary RS frame and a secondary RS frame. The block decoder performs turbo decoding of a SCCC block unit for mobile service data within the baseband broadcast signal based on SCCC-related information. The controller generates a control signal for RS frame decoding with reference to at least one of SCCC block mode information, RS frame mode information, and user's input. The RS frame decoder configures at least one of a primary RS frame and a secondary RS frame using the mobile service data output from the block decoder in accordance with the control signal and performs error correction decoding for corresponding RS frame with reference to reliability information of each mobile service data byte within the configured RS frame.

    摘要: A digital television receiving system includes a frame encoder, a data randomizing and expanding unit, a group formatter, a block processor, a deinterleaver, and a multiplexer. The frame encoder encodes an enhanced data frame for error correction. The data randomizing and expanding unit randomizes the encoded enhanced data and expands the randomized enhanced data. The group formatter forms a group of enhanced data having head, body, and tail regions and inserts the expanded data and transmission parameters into the body region. The block processor codes the group of enhanced data, and the deinterleaver deinterleaves the coded enhanced data. The packet formatter formats the deinterleaved enhanced data into enhanced data packets.
