Abstract

PURPOSE:To attain an efficient transmission with one pulse string by loading the luminance signal of the widest frequency band out of component image signals at the pulse interval of a sampling value and alternately pulse-width- modulating the color-difference signal of the frequency band of a half or below the luminance signal at the half period. CONSTITUTION:By utilizing that respective color-difference signals of component image signals Y, CW and a half or below the frequency band of the luminance signal, the luminance signal out of the component image signals Y, CW and CN executes a pulse frequency modulation (PFM), and pulse-width-modulates (PWM) the pulse of this modulated PFM signal at a half period successively with the CW signal and CN signal. Thus, a high speed process is not required like a PCM multiplexed transmission and a pulse optical transmission can be executed with one emission element, further with the information of one pulse string irrespective of a linearity.
