Abstract:
1. A Vestigial Sideband (VSB) transmitter for transmitting main data and supplemental data, the VSB transmitter comprising: a pre-processor configured to pre-process the supplemental data by forward error correction (FEC) coding the supplemental data; a first multiplexer for multiplexing the main data and the pre-processed supplemental data; an encoder for forward error correction (FEC) coding the main and supplemental data; a data interleaver for interleaving the FEC-coded main and supplemental data; and a Trellis coder for Trellis-coding the interleaved main and supplemental data, wherein memories of the Trellis coder are initialized and output of the Trellis coder is known according to input of the Trellis coder.
