Abstract
A semiconductor integrated circuit which transmits voice data as ancillary data while maintaining transmission quality without increasing the number of transmission cables in a system for carrying out serial transmission of image data as main data. The semiconductor integrated circuit includes a main data transmitting circuit for converting main data into serial data and transmitting the serial data via at least one transmission path in synchronization with a clock signal, and an ancillary data transmitting circuit for pulse-width-modulating the clock signal by using ancillary data to generate a modulated clock signal having at least three kinds of pulse widths in a predetermined order and transmitting the modulated clock signal via another transmission path.
