Title: Innovations of Jong Kyung Yun

Introduction

Jong Kyung Yun is a notable inventor based in Suwon, South Korea. He has made significant contributions to the field of video signal processing, holding a total of six patents. His work focuses on enhancing the quality and efficiency of video signal reproduction.

Latest Patents

One of his latest patents is titled "Deemphasis and subsequent reemphasis of high-energy reversed-spectrum components of a folded video signal." This invention involves a system designed to reproduce a luminance signal from a medium that contains a previously recorded luminance signal. The system includes a circuit that recovers the luminance signal while filtering to separate low-frequency and high-frequency portions. The high-frequency portion is then processed to expand its dynamic range and reduce noise, ultimately reproducing a full-band luminance signal with improved quality.

Another significant patent is for a "System for recording and reproducing a wide bandwidth video signal." This invention separates luminance and chrominance signal components from a composite video signal. It detects frame-to-frame changes in the luminance signal to derive a motion signal. The higher frequency portion of the luminance signal is adaptively de-emphasized and folded into the spectrum of the lower frequency portion. This process generates a folded-spectrum luminance signal suitable for magnetic recording, facilitating compatibility with conventional VHS reproduction devices.
