Title: Richard C Nicol: Innovator in Television Transmission Technology
Introduction
Richard C Nicol is a notable inventor based in Ipswich, GB. He has made significant contributions to the field of television transmission technology, holding a total of 3 patents. His innovative methods have advanced the way television pictures are transmitted and stored.
Latest Patents
One of Nicol's latest patents is titled "Omission and subsequent estimation of zero sequency coefficients." This method involves dividing a television picture into multiple blocks, applying a two-dimensional unitary transformation to each block, and then transmitting or storing the transform coefficients. To optimize data rates, the zero sequency coefficient is often omitted, and adjustments are made to the mean levels of the reconstructed blocks to minimize visible brightness changes. This technique also addresses the common elements along inter-block boundaries, ensuring a seamless transition in picture quality.
Another significant patent is related to "Television signal standards conversion." This invention utilizes a television picture transmission system that employs conditional replenishment. It allows for a scanning rate at the transmitter that differs from the receiver, accommodating asynchronous operations and varying standards. The frame rate conversion is achieved through updating loops, which can either stop or repeat fields or frames to adjust the data rate. Temporal interpolation is used to reduce motion jerkiness, while spatial interpolation helps convert the number of lines per frame.
