A real-time source encoder for tv bandwidth compression. Lui, Hung Lam

Abstract

A TV bandwidth compression scheme based on psychophysical approach had been studied with an optical real-time processor. This thesis reports the design and instrumentation of an electronic version of the optical processor. The electronic processor is very close to an actual TV system. The processor requires relatively simple circuits, and performance checks are described. Subjective evaluation of the output picture, showed an improvement in picture quality for low compression ratios, less than 2. Above this ratio, the compression introduces excessive distortions.
