Title: The Innovative Mind of James Barrett

Introduction

James Barrett is a notable inventor based in Manchester, GB. He has made significant contributions to the field of video coding, particularly with his innovative patent that addresses the complexities of picture compression.

Latest Patents

James Barrett holds a patent for a method titled "Hybrid open-loop/closed-loop compression of pictures." This method involves forming a difference between input picture values and picture prediction values, which is then transformed using a Discrete Cosine Transform (DCT). The picture prediction is defined by the equation P=(1−c)P+CP, where P represents a closed-loop predictor restricted to values capable of exact reconstruction in a downstream decoder, while P is a spatial predictor unrestricted by such limitations. The factor c can vary from zero to unity based on various parameters. This innovative approach enhances the efficiency of video coding.
