Abstract
A video data transmitter apparatus generates and transmits a multi-value amplitude modulation signal by performing a multi-value amplitude modulation of a plurality of N bits per one symbol according to video data of a video signal or a color signal constituting the video signal, or a brightness signal and a color-difference signal. A data separator portion separates the video data into first to N-th pixel data, a difference calculator portion calculates (N−1) pieces of predetermined difference information based on the separated first to N-th pixel data, and a multi-value amplitude modulator portion performs a multi-value modulation so that predetermined N-bit data corresponds to a multi-value signal level closest to an intermediate level having an intermediate value between a maximum level and a minimum level of the multi-value signal level of the multi-value amplitude modulation signal.
