The present invention is applied to recording/reproducing apparatus such as a video tape recorder or video signal transmitting apparatus which comprises an decoder (36) and an encoder (16), and is arranged to separate luminance and two chrominance signal components from a composite video signal, to transmit an information signal indicative of the phase of chrominance subcarrier within the composite video signal on decoding; and to control the phase relationship between the composite video signal and chrominance subcarrier during encoding on the basis of the information signal thereby removing or minimizing distortion in high frequency range of the luminance signal and the chrominance signal.
摘要:
A magneto-electro-optic effect light modulator has a rectangular solid-like semiconductor element made of one member selected from the group of an n-type semiconductor, a p-type semiconductpr and an intrinsic semiconductor. The semiconductor element has no pn-junction and has a band-gap corresponding to the energy of infrared light concerned. Also provided are a magnet for applying a magnetic field H to the semiconductor element and electrodes for passing an electric current through the semiconductor element access the magnetic field. A power source supplies an electric current passing through the semiconductor element in order to modulate the light incident upon the semiconductor element. An entrance polarizer disposed in front of the semiconductor element linearly polarizes the infrared-light transmitting therethrough. An exit polarizer disposed behind the semiconductor element linearly polarizes the infrared-light transmitting therethrough, the exit polarizer has a polarization plane different form the entrance polarizer. The light modulator utilizes the population inversion causd by a cooperation of current J and magnetic field H to modulate the light incident upon the semiconductor element.
