Title: The Innovations of Seiho Kitaji
Introduction
Seiho Kitaji is a notable inventor based in Yokohama, Japan. He has made significant contributions to the field of optical transmission systems, holding a total of 3 patents. His work focuses on enhancing video signal transmission through innovative technologies.
Latest Patents
Kitaji's latest patents include a multi-channel video optical transmission system, an optical transmitter, and an optical receiver. The multi-channel video optical transmission system features a frequency modulation function that generates a pilot signal frequency-modulated. This pilot signal is superimposed on a multi-channel video signal and transmitted through an optical fiber, where it is converted into an optical signal. The optical receiver then converts the optical signal back into an electric frequency-modulated signal, allowing for the regeneration of the multi-channel video signal. This technology effectively eliminates distortion and enhances the quality of video transmission.
Another significant patent is the HDTV signal transmission apparatus. This system is designed to send a 10-bit-parallel YPbPr-format HDTV signal, which is converted into ten C4 containers for transmission. The system includes both a transmitter and a receiver, with various devices for multiplexing and demultiplexing the video signals. This innovation adheres to CCITT recommendations and improves the efficiency of HDTV signal transmission.
