Title: Shigenori Onaka: Innovator in Video Signal Technology
Introduction
Shigenori Onaka is a notable inventor based in Yokosuka, Japan. He has made significant contributions to the field of video signal technology, holding a total of 2 patents. His work focuses on enhancing the quality and functionality of video transmission and reception systems.
Latest Patents
Onaka's latest patents include a video signal transmitter/receiver and a color video signal dubbing system. The video signal transmitter/receiver apparatus is designed to automatically switch the aspect ratio at a receiving device. It outputs a chrominance signal and a luminance signal separately, converting the chrominance signal into a low impedance. A transistor and resistive divider network superpose a DC voltage controlled by an aspect ratio control signal on the output signal. The receiving unit inputs the chrominance and luminance signals separately and includes a discrimination circuit that detects the DC control voltage superposed on the chrominance signal.
The color video signal dubbing system comprises a reproducing apparatus and a recording apparatus. The recorded signal is a multiplexed signal of a frequency-modulated luminance signal and a frequency-converted carrier chrominance signal. The reproducing apparatus features a separation circuit for separating the reproduced signal into its components, along with various circuits for level adjustment and frequency characteristic compensation.
