Patent ID: 7555066

Claim:
An E8-VSB (enhanced 8-vestigial sideband) reception system for receiving and processing data where main data and enhanced data are multiplexed and transmitted, the system comprising: a VSB receiver for converting a received broadcast signal of a predetermined channel into a digital baseband signal in synchronization with a first symbol clock, converting a decision signal synchronized with a second symbol clock into a decision signal synchronized with the first symbol clock, performing a channel equalizing, noise removal on the digital baseband signal using the converted decision signal, and an error correction on the noise removed signal, and outputting error-corrected data and a synchronization signal in synchronization with the first symbol clock and the second symbol clock; and an enhanced data processor for receiving the data and the synchronization signal in synchronization with the first symbol clock and the second symbol clock from the VSB receiver, extracting enhanced data from the data according to the synchronization signal, performing E8-VSB decoding and error correction, and outputting the decision signal synchronized with the second symbol clock to the VSB receiver.
