Title: The Innovations of Makoto Hiraoka
Introduction
Makoto Hiraoka is a notable inventor based in Tokyo, Japan. He has made significant contributions to the field of television signal processing, holding a total of 3 patents. His work focuses on enhancing the reliability of signal transmission through innovative encoding and decoding techniques.
Latest Patents
Hiraoka's latest patents include a system for detecting transmission errors in inter-frame encoding and decoding equipment for television signals. This system consists of inter-frame encoding equipment that generates an encoded signal by encoding the difference between television signals and the output of a frame memory. The inter-frame decoding equipment receives this encoded signal via a transmission line and decodes it by adding the output of the frame memory to the encoded signal. The encoding equipment features a first operation circuit that calculates remainders obtained by dividing a predetermined value into bit groups of the output or input of the frame memory. Similarly, the decoding equipment includes a second operation circuit that performs the same calculations. Additionally, a comparator circuit is integrated to compare and check the remainders calculated by both operation circuits to detect any transmission errors.
