Abstract
Se proporcionan dispositivos y métodos para intrapredicción del modo de intrapredicción DC. El método incluye: obtener un valor de un índice de línea de referencia de intrapredicción de un bloque de transformada; obtener muestras de predicción del bloque de transformada con base en muestras de referencia de una línea de referencia. La línea de referencia se indexa por el valor del índice de línea de referencia de intrapredicción. El método introduce una armonización de MRL e intrapredicción no direccional (es decir, DC). La armonización consiste en alinear las muestras de referencia de una línea de referencia, que se indexa por el valor del índice de línea de referencia de intrapredicción.
