Patent ID: 6980603

Claim:
A Vestigial Sideband (VSB) transmission system comprising: a supplemental data processor processing input supplemental data including encoding, inserting a null sequence, and inserting an MPEG header; a multiplexer multiplexing said supplemental data processed in said supplemental data processor and MPEG data; a first encoding part processing said multiplexed data including data randomizing, adding a first parity, data interleaving, and byte-symbol converting; a second encoding part encoding said data processed in said first encoding part with a 1/N coding rate if said first encoding part receives said supplemental data from said multiplexer, N being a natural number; a decoding part processing said data encoded in said second encoding part including symbol-byte converting, data deinteleaving, and eliminating said first parity added in said first encoding part; and a VSB transmitter processing said data processed in said decoding part including trellis encoding, adding a second parity, data interleaving, VSB modulating, and transmitting to a receiving side.
