Abstract

Un método de codificación de video de conformidad con la modalidad de la presente descripción incluye: obtener una anchura de una imagen con base en información acerca de la anchura de la imagen obtenida de una corriente de bits y obtener una altura de la imagen con base en información acerca de la altura de la imagen obtenida de la corriente de bits; cuando una coordenada x de conformidad con una anchura de luma de un bloque actual generado de la imagen no es mayor que la anchura de la imagen, una coordenada y de conformidad con una altura de luma del bloque actual no es mayor que la altura de la imagen, y un modo de división de un bloque de luma del bloque actual es un modo de no división, que decodifica el bloque de luma; y determinar un bloque de croma que corresponde al bloque de luma y decodificar el bloque de croma, en donde la información acerca de la anchura de la imagen indica un número de muestras de luma dispuestas en una dirección de anchura de la imagen, el número de muestras de luma dispuestas en la dirección de anchura es un múltiplo entero de 8, la información acerca de la altura de la imagen indica un número de muestras de luma dispuestas en la dirección de altura de la imagen, y el número de muestras de luma dispuestas en la dirección de altura es un múltiplo entero de 8.
