Abstract
Se proporciona un método para construir una lista de modos más probables, MPM, para proceso de predicción correspondiente al bloque de video. El método incluye determinar si un bloque izquierdo de un bloque de codificación actual está disponible o no, si el bloque izquierdo del bloque de codificación actual está disponible, añadir un modo de intrapredicción del bloque izquierdo a una lista MPM; determinar si un bloque por encima del bloque de codificación actual está disponible o no, si el bloque por encima del bloque de codificación actual está disponible, añadir un modo de intrapredicción del bloque anterior a la lista MPM; añadir un desplazamiento al modo de predicción del bloque izquierdo para obtener un nuevo modo de predicción, si el bloque izquierdo del bloque de codificación actual está disponible y el modo de intrapredicción del bloque izquierdo es un modo angular; y añadir el nuevo modo de predicción a la lista MPM, si el nuevo modo de predicción no está en la lista MPM; o añadir un desplazamiento al modo de predicción del bloque por encima para obtener un modo de predicción de desplazamiento por encima, si el bloque por encima del bloque de codificación actual está disponible y el modo de intrapredicción del bloque por encima es un modo angular; y añadir el modo de predicción de desplazamiento por encima a la lista MPM, si el modo de predicción de desplazamiento por encima no está en la lista MPM. La lista MPM se utiliza para obtener un valor de índice correspondiente a un modo de predicción de un bloque de imagen, para mejorar la eficiencia de codificación.
