Abstract

Se proporcionan métodos y dispositivos para rectificar un problema de longitud de bits de codificación de asignación hacia adelante introducido por LMCS; en un método, una pluralidad de muestras de predicción, en un dominio asignado, de componente luma de una CU que se codifica por un modo de CIIP bajo estructura de LMCS se obtiene, una pluralidad de muestras residuales, en el dominio asignado, del componente luma de la CU se obtiene, la pluralidad de muestras de predicción en el dominio asignado se agrega a la pluralidad de muestras residuales en el dominio asignado, que resulta en una pluralidad de muestras reconstruidas, en el dominio asignado, de componente luma, y la pluralidad de muestras reconstruidas del componente luma se convierte en el dominio asignado en un dominio original con base en una pluralidad predefinida de factores de escalamiento de asignación inversa.
