Title: Takaya Morita: Innovator in Television Technology

Introduction

Takaya Morita is a prominent inventor based in Tokyo, Japan. He has made significant contributions to the field of television technology, holding a total of 3 patents. His work focuses on enhancing video signal transmission and improving television systems.

Latest Patents

Morita's latest patents include an apparatus for transmitting an extended definition TV signal. This invention involves a transmitting and receiving apparatus designed to transmit an input video signal with 525 lines per field progressive scanning. The apparatus converts the input video signal into a signal compatible with the NTSC system. It reproduces a video signal with the same specifications from the NTSC-compatible signal. The transmitting apparatus features a first separating system that isolates vertical high-frequency components in a three-dimensional horizontal-vertical-temporal domain from the input video signal. Additionally, it includes a modulating system that modulates the separated components using μ-modulation. A filtering system removes lower sideband components from the modulation output, ensuring a Nyquist characteristic. The receiving apparatus has a second separating system that processes the multiplexed filtered output from the NTSC-compatible signal, ultimately reproducing a video signal with 525 lines per field progressive scanning.

Another notable patent is for an aspect ratio-improved television system compatible with conventional systems. This invention produces a source television signal for a wide-aspect television screen, maintaining the same horizontal and vertical synchronizing frequencies while having fewer effective scanning lines than traditional systems. The system expands the time base of the source television signal horizontally by a predetermined ratio. It also includes apparatus for receiving the time base-expanded television signal, arranging video information from both side areas into top and bottom added scanning lines.
