Title: Gang-Janp Lin: Innovator in Audio Signal Processing and Motion Estimation

Introduction

Gang-Janp Lin is a notable inventor based in Taur-Yuan, Taiwan. He has made significant contributions to the fields of audio signal processing and motion estimation, holding two patents that showcase his innovative approaches.

Latest Patents

One of his latest patents is titled "High-efficiency algorithms using minimum mean absolute error splicing." This method involves modifying parameters of audio signals by dividing a digital signal converted from an original analog signal into sound frames. The process includes modifying the pitch and playing rate of the digital signal within a frame, followed by splicing the last modified frame with the first non-modified frame. The mean absolute error is calculated to define the best splicing point, aiming to produce minimal or no audible noise. This allows various sections of sound signals to be spliced together effectively. An apparatus for implementing this method is also disclosed, which includes input and output amplifiers, low pass filters, analog-to-digital and digital-to-analog converters, and a pitch shifting processor.

Another significant patent is the "Area/time-efficient motion estimation micro core." This invention proposes an efficient micro architecture for motion estimation that achieves better time and area performance compared to existing structures. By utilizing pipelining and effective manipulation of 2's complement arithmetic, the adder complexity is minimized while maintaining high speed for combined subtraction, absolution, and accumulation operations, making it as fast as a carry-save addition.
