Title: Kou-Hu Tzou: Innovator in Video Signal Processing
Introduction
Kou-Hu Tzou is a notable inventor based in Marlboro, NJ (US). He has made significant contributions to the field of video signal processing, holding a total of 4 patents. His work has advanced the technology used in motion estimation and variable-length codeword encoding.
Latest Patents
One of Tzou's latest patents is the "Unified motion estimation architecture." This invention describes a video signal processor that includes a motion vector estimation system capable of operating in two modes: frame-structure processing and field-structure processing. The system comprises N motion estimator units, each receiving two respective time-separated data blocks. In the first operating mode, N units function, while in the second mode, M of the N units are active, with (N-M) units providing motion estimating processing outside the image area represented by the data blocks. Notably, N is an integer greater than 2, and M is an integer less than N.
Another significant patent is the "Variable-length codeword encoder." This encoder produces 8-bit output segments for storage in a buffer for subsequent transmission over a channel. It includes two memory tables that generate a variable-length codeword and a codeword length in response to each input symbol. An accumulator accumulates the successive codeword lengths, producing a carry signal when eight or more bits are accumulated. The variable-length codeword is then processed through a crossbar shift control circuit, resulting in a 16-bit output that embeds the input word.
