A liquid crystal display has a liquid crystal layer, a first electrode substrate; and a second electrode substrate provided as facing the first substrate so that the liquid crystal layer is sandwiched by the first and the second substrates. The system analyzes pixels of the image that correspond to an \u201cedge\u201d between two colors of the scene. The VSB reception system also includes a supplemental data processor for processing the supplemental data segment from the demultiplexer in a reverse order of the transmission system, to obtain the supplemental data, thereby carrying out the slicer prediction, decoding, and symbol decision more accurately by using the predefined sequence, to improve a performance. After that, waveform rounding that is generated at the time of releasing the signal line is reduced to enable higher communication speed.
