Title: Siu-Leong Yu: Innovator in Video Compression Technology
Introduction
Siu-Leong Yu is a notable inventor based in San Jose, CA. He has made significant contributions to the field of video compression technology. With a total of 3 patents to his name, Yu has demonstrated his expertise and innovative spirit in developing advanced encoding techniques.
Latest Patents
One of Yu's latest patents is titled "Intra-prediction using intra-macroblock motion compensation." This invention focuses on encoding unencoded blocks of a frame by defining a search window within the frame. Each pixel within the search window is assigned a value, and a difference is computed between the unencoded block and each possible block within the search window. The block with the smallest difference is used to encode the unencoded block, enhancing the efficiency of video encoding.
Another significant patent is "Bit rate control for motion compensated video compression system." This invention involves accumulating a portion of the bits initially allocated for encoding some frames of a group of pictures (GOP) in a bit bank. This accumulated data is then used to encode other frames that may require more bits than initially allocated. Additionally, when a scene change P frame is detected, a second GOP is formed, which includes the scene change P frame and the remaining unencoded frames of the original GOP. This innovative approach optimizes the encoding process and improves video quality.
