Abstract

Un método de procesamiento de medios visuales incluye la determinación del tamaño de un búfer para almacenar las muestras de referencia para la predicción en un modo de copia intra-bloque; y llevar a cabo una conversión entre un bloque de video actual de los datos de medios visuales y una representación del flujo de bits del bloque de video actual, a través del uso de las muestras de referencia almacenadas en el búfer, en donde la conversión se lleva a cabo en el modo de copia intra-bloque que se basa en la información de movimiento relacionada con un bloque reconstruido ubicado en la misma región de video que el bloque de video actual sin hacer referencia a una imagen de referencia.
