Abstract

Un codificador (100) que codifica un bloque actual en una imagen incluye circuitería y memoria. Usando la memoria, la circuitería: divide el bloque actual en un primer sub-bloque, un segundo sub-bloque y un tercer sub-bloque en una primera dirección, el segundo sub-bloque se ubica entre el primer sub-bloque y el tercer sub-bloque; impide dividir el segundo sub-bloque en dos particiones en la primera dirección; y codifica el primer sub-bloque, el segundo sub-bloque y el tercer sub-bloque.
