Abstract

Se proporcionan métodos y aparatos para codificación de video con modos de codificación sin pérdidas. El método incluye: dividir una imagen de video en una pluralidad de CUs comprendiendo una CU sin pérdidas; determinar un tamaño de bloque de codificación restante de la CU sin pérdidas; y en respuesta a determinar que el tamaño de bloque de codificación restante de la CU sin pérdidas es mayor que un valor máximo predefinido, separando el bloque de codificación restante en dos o más bloques restantes para codificación restante.
