Title: Jason S Brownell: Innovator in Digital Watermarking

Introduction

Jason S Brownell is a notable inventor based in San Francisco, California. He has made significant contributions to the field of digital signal processing, particularly in the area of watermarking technology. His innovative approach has led to the development of a robust method for encoding watermark data in digital signals.

Latest Patents

Brownell holds a patent for a "Robust watermark method and apparatus for digital signals." This patent describes a process where watermark data is encoded in a digitized signal by forming a noise threshold spectrum. This spectrum represents the maximum amount of imperceptible noise, which is then spread-spectrum chipped with a continuous stream of pseudo-random bits to create a basis signal. The basis signal is divided into segments, and these segments are filtered to smooth out boundaries. The encoded watermark data is precoded to ensure robustness against inversion and is convolutional encoded to enhance the likelihood of retrievability, even after lossy processing of the watermarked signal.

Career Highlights

Throughout his career, Jason S Brownell has worked with prominent companies such as Liquid Audio, Inc. and Microsoft Corporation. His experience in these organizations has allowed him to refine his skills and contribute to groundbreaking projects in digital technology.
