    摘要： 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 deiniterleaves the group of enhanced data, and the packet formatter formats the deinterleaved data into enhanced data packets.

    摘要： A DTV transmitting system includes two pre-processors. The first pre-processor codes high-priority enhanced data for forward error correction (FEC) and expands the FEC-coded data. The second pre-processor codes low-priority enhanced data for FEC and expands the FEC-coded low-priority enhanced data. The DTV transmitting system further includes a data formatter generating enhanced data packets including the pre-processed data, a multiplexer multiplexing the enhanced data packets with main data packets, an RS encoder RS-coding the multiplexed data packets, a data interleaver interleaving the RS-coded data packets, and a block processor which codes each block of enhanced data in the interleaved enhanced data packets and bypasses the interleaved main data packets.

    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.
