Introduction: John Gordon Amery, an accomplished inventor based in Indianapolis, IN, has made significant strides in the field of video technology. With a remarkable portfolio of 8 patents, Amery's work continues to influence video recording and reproduction methods, enhancing the quality and efficiency of video signals.

Latest Patents: Among his latest innovations, Amery has developed a pivotal patent for video disc systems featuring plural preemphasis/deemphasis networks. This technology remarkably improves video recording apparatus by enabling a luminance signal to be doubly preemphasized, utilizing a cascade of two networks prior to clipping and application to a frequency modulator. One network provides a non-linear phase characteristic with an amplitude response that increases in the lower portion of the luminance band. The other network, characterized by a linear phase response, enhances the upper portion of this band. This strategic combination allows for reduced clipping distortion under transient signal conditions while enhancing the overall signal-to-noise ratio through complementary deemphasis networks.

Another essential innovation is Amery's chrominance signal limiter. This invention employs a filter to effectively separate composite video signals into their luminance and chrominance components. Through controlled regulation against reference voltages, the chrominance signal is limited symmetrically relative to the luminance level, thereby mitigating harmonic distortion. These advancements signify Amery's commitment to enhancing video technology and ensuring superior signal quality.

Career Highlights: John Gordon Amery's career is marked by his contributions to RCA Inc., a leading player in the electronics industry. His work at RCA Inc. has facilitated the development of cutting-edge video technologies that have broadly impacted media consumption and broadcasting.
