Title: Edward Atrero: Innovator in Digital Data Transport

Introduction

Edward Atrero is a notable inventor based in San Diego, CA. He has made significant contributions to the field of digital data transport, holding 2 patents that showcase his innovative approach to embedding auxiliary information within primary digital signals.

Latest Patents

Atrero's latest patents include a system for Digital Hidden Data Transport (DHDT). This system allows for the embedding of auxiliary digital information into a primary digital signal, creating a composite digital signal. The method involves modulating auxiliary data bits with a pseudo-random sequence to modify the Least Perceptually Significant Bits (LPSBs) of successive multi-bit samples of the primary signal. In a cross-term compensation embodiment, a correlation between the pseudo-random sequence and the sample bits is determined to ensure a desired correspondence. The selection of LPSBs to modify is carefully considered to maintain a desired noise level of the auxiliary data within the primary signal.

Another patent focuses on a digital system for embedding a pseudo-randomly modulated auxiliary data sequence in digital samples. This system also aims to create an unobjectionable composite digital signal by modifying the LPSBs of the primary digitally encoded signal. The data to be hidden can encompass any digital information, while the primary signal can include both uncompressed and compressed digitally sampled processes, such as audio or video data.
