Introduction

Soon Hwa Jang is a notable inventor based in Taejeon, South Korea. She has made significant contributions to the field of video encoding and integrated circuit design. With a total of 4 patents, her work focuses on enhancing data processing and video quality.

Latest Patents

One of her latest patents is a method for controlling the data bit rate of a video encoder. This method is designed to achieve optimal bit rate control in accordance with a video signal band compression scheme. It utilizes differential pulse code modulation (DPCM) and discrete cosine transform (DCT) techniques to ensure supreme picture quality while preventing buffer overflow or underflow phenomena. The method involves determining an initial bit allocation for every group of pictures (GOP) and allocating bits for each picture and macroblock, ultimately determining a quantizer step size proportional to the bit allocation.

Another significant patent is a very large scale integrated circuit for performing a bit-serial matrix transposition operation. This circuit includes an input shift register module, a bit-serial transposition module, an output multiplexer module, and an output register module. The design allows for high-speed operations and reduces the number of gates required in the integrated circuit. The pipelined structure of the circuit makes it suitable for multi-dimensional signal processing systems that require high-speed processing.
