Abstract

Se describe un metodo de codificacion de longitud variable para convertir por frecuencia datos de imagen en una imagen en movimiento en unidades de bloque que tienen un tamano predeterminado y codificar un valor de coeficiente en cada uno de los bloques. El metodo incluye una etapa de escaneo de valores de coeficiente para escanear los valores de coeficiente en un bloque en un orden predeterminado y una etapa de codificacion para cambiar una pluralidad de tablas usadas para codificar y decodificar los valores de coeficiente escaneados en la etapa de escaneo de valores de coeficiente en codigos de longitud variable en un orden predeterminado. Aqui, el cambio de las tablas mencionadas anteriormente puede ser en una direccion. Mas aun, la codificacion anterior puede ser codificacion no aritmetica.
