Title: Innovations of Hirohisa Shiojiri
Introduction
Hirohisa Shiojiri is a notable inventor based in Tokyo, Japan. He has made significant contributions to the field of moving picture transmission technology. With a total of three patents to his name, Shiojiri's work has advanced the way visual information is transmitted and received.
Latest Patents
One of his latest patents is titled "Moving picture transmission system and moving picture transmission apparatus used therein." This invention includes a transmission apparatus and a reception apparatus. The transmission apparatus transmits a maximum number of pieces of information obtained by hierarchically coding moving picture information according to degrees of importance in terms of image quality. This process occurs within a moving picture frame period, in the order of decreasing degrees of importance. The reception apparatus then reproduces a moving picture frame based on the hierarchically coded information received during the frame period.
Another significant patent is "Picture information transmission system and picture coding and decoding." This system enciphers and transmits picture information after interframe coding. It allows a receiving apparatus, which lacks a cipher decoding device, to decode and display the picture at any arbitrary time. This feature is particularly useful for advertising purposes, as it enables potential customers to view the image. The system is designed to stop coding for a predetermined period, during which data from one of several regions of each frame is successively coded by intraframe coding before being outputted.
