A VSB reception system includes a sequence generator for decoding a symbol corresponding
to the supplemental data and generating a predefined sequence included in the supplemental
data at VSB transmission system. The reception system also includes a modified
legacy VSB receiver for processing the data received from the VSB transmission
system in a reverse order of the VSB transmission system by using the sequence,
and a demultiplexer for demultiplexing the data from the modified legacy VSB receiver
into the MPEG data and the supplemental data. The VSB reception system also includes
a supplemental data processor for processing the supplemental data segment from
the demultiplexer in a reverse order of the transmission system, to obtain the
supplemental data, thereby carrying out the slicer prediction, decoding, and symbol
decision more accurately by using the predefined sequence, to improve a performance.
