Abstract

La presente invención se refiere a un método para comprimir un dato de video de color digital en un sistema de comunicación de video, para transmitir una pluralidad de cuadros de imagen de video, con cada cuadro de imagen consistiendo de una pluralidad de líneas de exploración compuestas de una pluralidad de pixels. utilizando una señal de video de color digitizada que tiene tres componentes de color digitales, el sistema incluye un medio para determinar una función de luminancia para cada pixel, un medio para determinar cual de los pixels en cada línea de exploración representa los punto de decisión basándose en la función de luminancia, y un medio para codificar por lo menos una porción de la pluralidad de pixels en cada línea de exploración como una pluralidad de combinaciones de longitudes de recorrido y los tres componentes de color digitales, la longitud de recorrido es de un primer tamaño de palabra digital, y los tres componentes digitales de color siendo de segundo, tercero y cuarto tamaños de palabra digital respectivamente, que consiste de los pasos de: a) codificar todos lo componentes de color digitales en el cuadro de imagen de acuerdo con un cuadro de consulta en un medio de memoria de códigos de color digitalmente comprimidos de las combinaciones de color más significativas visualmente de un quinto tamaño de palabra digital más pequeño que la suma del segundo, tercero y cuarto tamaños de palabra digital; y b) codificar una pluralidad de longitudes de recorrido y los códigos de color digitalmente comprimidos que representan por lo menos una porción del cuadro de imagen en el medio de memoria.
