Title: Ichiro Yuyama: Innovator in High-Definition Video Technology
Introduction
Ichiro Yuyama is a prominent inventor based in Tokyo, Japan. He has made significant contributions to the field of video technology, particularly in high-definition systems. With a total of 2 patents, Yuyama's work has advanced the way video signals are processed and transmitted.
Latest Patents
Yuyama's latest patents include a "Receiver and channel compatible encoding/decoding system for high-definition video signals." This innovative system combines high-resolution vertical and horizontal components of a high-definition video signal with a standard broadcast system video signal, such as the NTSC system. The high-frequency horizontal resolution components are sampled and used to modulate a first sub-carrier signal, which is frequency interleaved onto the standard broadcast signal. Vertical high-resolution components are time-compressed and time-division multiplexed onto the top and bottom portions of the standard broadcast signal. This modified broadcast signal can be decoded by standard receivers to display a standard resolution video image. Receivers designed to decode the modified signal can time-division demultiplex the vertical high-resolution components and demodulate the horizontal high-resolution components, ultimately generating a high-definition video image.
Another notable patent is the "Stereoscopic television picture transmission system," which further showcases Yuyama's expertise in enhancing video transmission technologies.
