vestigial sideband receive system

PURPOSE: A VSB(Vestigial Sideband) receiving system is provided to install a sequence generator predefined in a transmission system, informing of a symbol of additional data and generating a sequence included in the additional data, thereby exactly performing a slier prediction, a decoding process, and a symbol deciding of the additional data. CONSTITUTION: A sequence generator(46) indicates a symbol of additional data, and is predefined while coding the data in a transmission system, then generates a sequence included in the symbol of the additional data. An MPEG data processor(100) processes MPEG data received from the transmission system, in reverse order of processing the MPEG data in the transmission system by using the sequence. A demultiplexer(56) demultiplexes the data outputted from the MPEG data processor, and separates the data into an MPEG data segment and an additional data segment. An additional data processor(200) processes the additional data segment outputted from the demultiplexer in reverse order of processing the additional data in the transmission system, and restores the data to the original additional data.
