Abstract
A television transmitting system includes an encoder, a data randomizing and expanding unit, a group formatter, a deinterleaver, and a packet formatter. The encoder codes enhanced data for error correction, permutes the coded data, and further codes the permuted data for error detection. The randomizing and expanding unit randomizes the error-detection-coded data and expands the randomized data. The group formatter forms a group of enhanced data having one or more data regions and inserts the expanded enhanced data into at least one of the regions. The deinterleaver deinterleaves the group of enhanced data, and the packet formatter generates enhanced data packets.
