    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 encodes the frame two times for first and second error correction, respectively. It further permutes a plurality of encoded data frames. The randomizer randomizes the permuted enhanced data, 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 data coded at the rate of 1/N1 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.

    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.
