Patent ID: 7092455

Claim:
A Vestigial Sideband (VSB) transmission system comprising: a supplemental data processor processing supplemental data including Reed-Solomon encoding, inserting a plurality of null bits, and inserting an MPEG header; a first multiplexer multiplexing MPEG data and said data processed in said supplemental data processor; a data encoding part processing said multiplexed data including data randomizing, adding a first Reed-Solomon parity, data interleaving, and byte-symbol converting in order to generate an input data symbol; a supplemental data symbol processor encoding an information bit of said input data symbol with a ½ coding rate; a data decoding part processing said data processed in said supplemental data symbol processor including symbol-byte converting, data de-interleaving, eliminating said first Reed-Solomon parity added in said data encoding part; and a VSB transmitter processing said data processed in said data decoding part including trellis encoding, adding a second Reed-Solomon parity, data interleaving, VSB modulating, and transmitting to a receiving side.
