Abstract

Se proporcionan un método y un aparato de intrapredicción para la reconstrucción de muestras de referencia no disponibles. El método incluye obtener un modo de intrapredicción de un bloque actual, derivar la disponibilidad de una muestra de referencia de un componente del bloque actual, sustituir muestras de referencia no disponibles mediante el uso de muestras de referencia disponibles, derivar una predicción del bloque actual basada en el modo de intrapredicción. y las muestras de referencia sustituidas, y reconstruir el bloque actual con base en la predicción. El componente incluye un componente Cb o un componente Cr. Alternativamente, el componente incluye un componente Croma. Dado que el método deriva la disponibilidad de la muestra de referencia en cada componente, puede proporcionar la información disponible con mayor precisión.
