Abstract:
1. An enhanced VSB receiver for receiving and decoding a terrestrial broadcasting signal transmitted from a VSB transmitter, the enhanced VSB receiver comprising: a main VSB processor for receiving an input signal including main data and enhanced supplemental data from the VSB transmitter, processing the input signal in a reverse order of the VSB transmitter, and outputting a multiplexed data signal; a demultiplexer for demultiplexing the multiplexed data signal received from the main VSB processor into the main data and the enhanced supplemental data; and a supplemental VSB processor for decoding the enhanced supplemental data, demultiplexed from the demultiplexer to obtain original supplemental data, wherein a plurality of null bits are inserted into the enhanced supplemental data at predefined locations by the VSB transmitter before data transmission for enhancing the data reception performance of the main VSB processor.
