Abstract
An information signal processing apparatus discriminates a significance factor of an input information signal. A modulation process of the information signal is determined in accordance with the discriminated significance factor. The modulated information signal is transmitted to an external apparatus. Since the modulation process of an information signal to be transmitted is controlled basing upon the significance factor of the information signal, both the transmission error rate and transmission rate can be optimized.
