Title: Jooyoung Yi: Innovator in Scalable Video Coding

Introduction

Jooyoung Yi is a prominent inventor based in Seongnam, South Korea. He has made significant contributions to the field of video coding, particularly through his innovative methods that enhance the efficiency of video processing.

Latest Patents

Jooyoung Yi holds a patent for a "Method and apparatus for scalable video coding." This scalable video coding method involves dividing an enhancement layer into macroblocks. When the base_mode_flag or residual_prediction_flag of the macroblock is equal to 1, it calculates a reference block coordinate value of a reference layer for block up-sampling of the enhancement layer. The macroblocks of the enhancement layer are then up-sampled using this coordinate value, followed by coding the up-sampled macroblock. This method significantly increases the execution speed of the scalable video codec while reducing the memory usage required for spatial inter-layer prediction.
