Abstract
Se proporcionan dispositivos y métodos para la intrapredicción. El método incluye: obtener un valor de una primera información de indicación de un bloque actual, el valor de la primera información de indicación que indica si un modo de intrapredicción del bloque actual está comprendido en un conjunto de modos más probables; y obtener un valor de una línea de índice de referencia del bloque actual. Cuando el valor de la primera información de indicación indica que el modo de intrapredicción del bloque actual está comprendido en el conjunto de modos más probables, y cuando el valor de la línea de índice de referencia indica que se utiliza la línea de referencia vecina más cercana al bloque actual, el método incluye además obtener un valor de una segunda información de indicación del bloque actual, indicando el valor de la segunda información de indicación del bloque actual si el modo de intrapredicción del bloque actual es el modo planar o no. El método puede mejorar la eficiencia para determinar el modo de intrapredicción del bloque actual.
