Title: The Innovative Mind of Dong-Wan Seo: Advancements in Video Transcoding
Introduction: Dong-Wan Seo is a prominent inventor hailing from Seoul, South Korea. With a remarkable portfolio that includes two patents, he has made significant contributions to the field of video transcoding. His work at Samsung Electronics Co., Ltd. has proven to be pivotal in enhancing video processing technologies.
Latest Patents: Dong-Wan Seo's latest patents focus on innovative methods and transcoders that estimate an output macroblock and motion vector for video transcoding. One of his notable inventions outlines methods for transcoding input macroblocks to an output macroblock. A crucial aspect of this method is the estimation of an output macroblock mode for video transcoding, utilizing spatial weights based on the size of overlapping areas of input macroblocks and correlation areas linked to the output macroblock. Additionally, a discrete cosine transform (DCT) weight is determined by analyzing the number of zero DCT coefficients of overlapping input macroblocks. This dual-weight estimation increases the accuracy of output macroblock mode determination.
In his second patent, Seo introduces a method for selecting output motion vectors that incorporates motion vector refinement. This involves generating a group of candidate motion vectors, selecting multiple reference vectors, and establishing a variably sized search window. By performing motion vector refinement within this search window, the output motion vector can be estimated more efficiently and accurately. The associated transcoder incorporates an encoding parameter estimator designed to optimize the selection of reference vectors and search window sizes, significantly improving output vector estimation without extending calculation times.
