Latest Patents

One of his latest patents is a method for video encoding that utilizes an intra updating technique based on error probabilities estimated from the size of the bit stream for each block. This video encoding method maximizes the intra updating effect by sorting out blocks that require intra updating based on bit stream size information. The process involves selecting an encoding method for incoming images, dividing the images into blocks, and determining whether to carry out intra or inter coded block encoding. This systematic approach ensures optimal encoding for each frame.

Another significant patent is an apparatus and method for fast discrete cosine transform (DCT) that maintains the same positions for input and output data. This innovation eliminates the need for additional memory by transposing the input data sequence and performing butterfly arithmetic operations. The method is applicable to both forward and inverse DCT, making it valuable for digital signal conversion and inversion.
