Title: Innovations of Yoshikazu Asano
Introduction
Yoshikazu Asano is a notable inventor based in Kakamigahara, Japan. He has made significant contributions to the field of sound decoding and television signal conversion. With a total of 3 patents to his name, Asano's work has had a considerable impact on audio and video technology.
Latest Patents
One of his latest patents is a broadcast/non-broadcast MUSE signal sound decoder. This innovative decoder detects a broadcasting/non-broadcasting identification flag included in the control signals of an applied MUSE signal. It determines whether the MUSE signal is broadcasted or non-broadcasted. The decoder also features a frame synchronization protection circuit that safeguards frame synchronization over a predetermined time period. This protection is crucial when the frame synchronization pattern is not detected at the proper timing. The circuit adjusts the protection time based on whether the MUSE signal is identified as broadcasted or non-broadcasted, allowing for appropriate muting of the sound signal according to the received MUSE signal's condition.
Another significant invention by Asano is a television signal converter. This converter transforms a sub-sample television signal, such as the MUSE signal, into a standard television signal. It utilizes odd field and even field vertical filters to process the MUSE signal, which is obtained from a high-density television signal through offset sub-sampling. The converter also includes time base expanders that select predetermined lines from the filtered signals and expand them on a time base, ensuring high-quality output.
