Title: Innovations by Robert W. Field

Introduction

Robert W. Field is an accomplished inventor based in Fountain Valley, CA (US). He has made significant contributions to the field of secure coding and transmission systems, holding a total of 3 patents. His work focuses on enhancing the security and efficiency of television program transmission.

Latest Patents

One of Field's latest patents is a secure coding and decoding system and method for television programs. This invention involves storing parts of a composite video signal in analog storage devices and retrieving them in a cyclic manner to rearrange and encode the signal. The retrieval process is selective and based on a pseudo-random signal generated independently at both encoding and decoding stations. Synchronization is achieved through a control word and an initialization word transmitted with the encoded video signal, with one of these words being encrypted. The decryption process utilizes a master key at both stations.

Another notable patent is a multiple signal transmission method and system. This invention describes a method for scrambling multiple input signals for secure transmission. The scrambling technique modulates an in-phase component of a carrier signal in response to various input signals in a sequence of time intervals. The quadrature component of the carrier signal is also modulated similarly, ensuring that both components together carry the entirety of the input signals. This method allows for the provision of additional audio signals, enabling multi-lingual program services alongside standard television audio and video signals.
