Title: Benedetto Riolfo: Innovator in Digital Signal Processing
Introduction
Benedetto Riolfo is a notable inventor based in Turin, Italy. He has made significant contributions to the field of digital signal processing, particularly in the area of television transmission and reception technologies. With a total of 3 patents to his name, Riolfo's work has had a lasting impact on the industry.
Latest Patents
Riolfo's latest patents include a circuit for computing the quantized coefficient discrete cosine. This innovative circuit consists of two parallel branches that perform multiplication and accumulation operations for the even and odd lines of the transform coefficient matrix. Each branch includes an input circuit (SEM1, SOT1) that allows for the addition of contributions from opposing index columns of the matrix. Additionally, a multiplication circuit (ERM, ORM) performs multiplication operations for each matrix column, along with an accumulation circuit for the intermediate products of each matrix column.
Another significant patent is the coder-decoder for the transmission and/or reception of television pictures. This device is designed for use via a digital low-speed channel. During transmission, it first executes a bidimensional transform of digital sample blocks of the television signal, followed by a dichotomic quantization to obtain quantized coefficients with variable lengths based on the coefficient index. In reception, it performs quantization for re-assignment of suitable quantization levels and then executes the bidimensional antitransform to recover the digital television signal samples.
Career Highlights
Throughout his career, Benedetto Riolfo has worked with prominent companies such as CSELT (Centro Studi e Laboratori Telecomunicazioni S.p.a.) and SIP (Società Italiana per l'Esercizio Telefonico P.a.). His experience in these organizations has allowed him to develop and refine his innovative ideas in telecommunications.
Collaborations
