Abstract

Un codificador incluye circuitería y memoria acoplada a la circuitería. La circuitería determina si se divide una unidad de decodificación de canal virtual de luminancia actual (VPDU, por sus siglas en inglés) en bloques más pequeños. Cuando se determina no dividir la VPDU de luminancia actual en bloques más pequeños, la circuitería predice un bloque de muestras de crominancia sin usar muestras de luminancia. Cuando se determina dividir la VPDU de luminancia en bloques más pequeños, la circuitería predice el bloque de muestras de crominancia por medio del uso de muestras de luminancia. La circuitería codifica el bloque por medio del uso de las muestras de crominancia predichas.
