Title: Innovations of Sang-Hee Cho
Introduction
Sang-Hee Cho is a notable inventor based in Seoul, South Korea. He has made significant contributions to the field of video signal processing, holding 2 patents that enhance picture quality in digital media.
Latest Patents
One of his latest patents is a "Method and apparatus for eliminating noise in a video signal encoder." This invention divides an input video signal into a noise component and a pure video signal component. It performs filtering gain control based on the energy rates of both components, thereby improving picture quality. The method also extracts a noise-filtered signal component in advance, allowing for effective filtering of the remaining signal while maintaining resolution. Additionally, it reduces blocking effects when processing video signals in block units.
Another significant patent is the "Decoder for digital TV receiver." This decoder enhances the picture quality of video signals down-converted for standard-definition TV receivers when receiving high-definition video signals. It processes data in block units, converting formats for display, and memorizing and reproducing data while downsampling in a specified ratio. This innovation ensures that more horizontal color signals are included than vertical color signals, ultimately improving the viewing experience.
