Abstract

Se proporcionan aparatos y métodos para las sub-particiones intra (ISP). El método incluye: obtener información de ISP, y determinar un tamaño de un bloque de transformación de croma (TB) de la unidad de codificación basado en SubWidthC y SubHeightC cuando se cumple al menos una primera condición. La primera condición incluye la información de ISP que indica que ISP se utiliza para dividir el bloque de codificación de luma. SubWidthC y SubHeightC son variables que dependen de la información del formato de croma. La información de formato de croma indica el formato de croma de una imagen a la que pertenece la unidad de codificación. El método puede aplicarse a todos los formatos de croma. El formato de croma incluye al menos uno de los siguientes: 4:2:0, o 4:2:2, o 4:4:4. Se consigue una forma precisa y versátil de determinar el tamaño del bloque de transformación de croma para el ISP.
