Title: Innovations of Yoshifumi Satake
Introduction
Yoshifumi Satake is a prominent inventor based in Yokohama, Japan. He has made significant contributions to the field of digital video technology, holding a total of 6 patents. His work has been instrumental in advancing the efficiency and quality of video signal processing.
Latest Patents
One of his latest patents is a digital video signal recording apparatus that utilizes variable-length coding. This innovative apparatus is designed to output a coded signal with a variable length per picture by compressing the amount of information in the digital video signal. It records the coded signal while forming multiple tracks in parallel on a tape-shaped recording medium. The compression ratio is adjusted to ensure that the coded signal corresponding to multiple pictures can be recorded efficiently across several tracks.
Another notable patent is an image encoding apparatus. This device outputs conversion data obtained by converting image information into a frequency region, corresponding to several frames, using a one-frame-period delay circuit. The conversion data is quantized by a quantization circuit, and the data amount to be obtained when the quantized data is encoded is determined by a variable-length coding circuit. This process enhances the efficiency of image encoding and improves overall data management.
