Title: The Innovative Contributions of Daniel Zhu
Introduction
Daniel Zhu is a notable inventor based in Churchville, PA (US), recognized for his contributions to video signal processing. With a total of 4 patents to his name, he has made significant advancements in the field of audio and video technology.
Latest Patents
One of his latest patents is focused on video luminance chrominance separation. This invention provides techniques for separating luma and chroma signal components in a composite SECAM video signal. During reception, the SECAM video signal is split into luma and chroma output. The amplitude of the chroma carrier is monitored during reception. If the chroma carrier amplitude exceeds a certain threshold, the value of the chroma output can be reduced. Additionally, if the chroma carrier amplitude surpasses another threshold, a portion of the chroma carrier can be added to the luma, or the trap band of the band-trap filter for extracting luma from the composite video can be reduced. The respective amounts of reduction in the chroma output and increase in the luma output are independently determined but may be proportional to the magnitude of the deviation in the chroma carrier amplitude from the different thresholds. Another significant patent is the audio/video separator, which provides a high-performance and cost-effective solution to analog TV reception with only one A/D converter and a minimum of analog IF components. This apparatus operates on a digitized TV signal and, when integrated with a digital video processor, processes video signals while separating audio signals. The resultant audio and video signals are considered to have excellent signal quality due to highly optimized demodulation architecture and digital signal processing techniques on both audio and video data paths.
