PROBLEM TO BE SOLVED: To maximize video reproducibility by minimizing the extent of skew of a receive signal by converting a clock signal, an enable signal, a vertical synchronizing signal, a horizontal synchronizing signal, and a series signal from a parallel/series conversion part into respective light signals and making them incident on an optical cable. SOLUTION: A reference signal generation part 2 is equipped with an inverter 21 and an AND gate 22 and when a break period based upon the enable signal EN starts, a reference signal SR having set data is generated. A parallel/series conversion part 4 performs the series conversion of the reference signal SR corresponding to the break period and parallel video signals RP, GP, and BP corresponding to scanning periods. A light signal generation part 5 converts a 1st clock signal CK1, an enable signal EN, a vertical synchronizing signal VSYNC, a horizontal synchronizing signal HSYNC, and the series signal from the parallel/series conversion part 4 into light signals, which are made incident on an optical cable 6. Thus, the reference signal SR is transmitted in the break period. |
