Abstract

Un codificador (100) incluye la circuitería (160) y la memoria (162) acoplada a la circuitería (160), en la cual, en operación, la circuitería (160): divide una imagen actual para codificarla en dos o más mosaicos; codifica la imagen actual realizando la codificación sobre una base de rebanada, siendo la rebanada de forma rectangular y constituida por uno o más mosaicos o una parte de un mosaico obtenido por la división; y en la codificación de la imagen actual, excluye, de la información de encabezado, la información sobre una región ocupada por una rebanada ubicada en la esquina inferior derecha de la imagen actual.
