Title: Sheau-Bao Ng: Innovator in Television Technology

Introduction

Sheau-Bao Ng is a notable inventor based in Plainsboro, NJ (US), recognized for his contributions to television technology. He holds three patents that showcase his innovative approach to solving complex problems in video signal processing.

Latest Patents

One of his latest patents is the "Adaptive Television Deghosting System." This system operates on modulated video signals, including a direct signal component and ghost signal components. It utilizes synchronously demodulated in-phase and quadrature-phase baseband video signals as real and imaginary input signals to a complex IIR filter. The filter coefficients are adaptively developed from preset initial values using signals provided during a training interval. This training interval is defined by the leading edge of the vertical sync pulse and the first serration pulse of each field. The system effectively cancels ghost signals by adjusting filter coefficients based on error signals.

Another significant patent is the "Digital Correlation Apparatus for a Television Deghosting System." This invention includes an IIR filter with programmable coefficients that processes input signals to eliminate ghost signal components. The filter can be reconfigured as an FIR filter, allowing it to operate as a matched correlation filter. This capability enables the system to correlate a training signal to determine the relative delays of ghost signals concerning the direct signal.
