Abstract: A VSB communication system comprises a VSB transmission system and a VSB reception system. The VSB transmission system multiplexes a coded MPEG data and a coded supplemental data having a null sequence inserted therein, with required multiplexing information included in a field synchronization signal or in a supplemental data according to a number of the supplemental data packets being transmitted. The VSB reception system detects the required multiplexing information from the field synchronization signal or the supplemental data and decodes the multiplexed data by using the null sequence and the detected multiplexing information, as well as demultiplexes the multiplexed data into the MPEG data and the supplemental data.

Abstract: A digital television system performing modulation/demodulation by VSB (vestigial side band) is provided. The invention includes a VSB transmitter including an additional error correction encoder designed such that a signal mapping of a TCM encoder is considered, a multiplexer (MUX), a TCM encoder operating in correspondence with state transition processes of the additional error correction encoder, and a signal transmission part including an RF converter. The invention further includes a VSB receiver including a signal receiver part receiving a signal transmitted from the transmitter, a TCM decoder, a signal processing part including a derandomizer, and an additional error correction decoder part.
