Abstract
Se proporciona un procedimiento de decodificación de predicción, un aparato de decodificación de predicción y un medio de almacenamiento informático. El procedimiento incluye lo siguiente. Obtener un primer conjunto de muestras de referencia vecinas obteniendo muestras de referencia vecinas de un bloque de codificación, en el que el primer conjunto de muestras de referencia vecinas incluye muestras de referencia en una fila de referencia o una columna de referencia vecina al bloque de codificación. Determinar las posiciones que corresponden a K muestras de referencia desde una posición de inicio de la fila de referencia o la columna de referencia, en las que K es un número entero positivo. Obtener un segundo conjunto de muestras de referencia vecinas de acuerdo con las posiciones determinadas que corresponden a las K muestras de referencia, en el que el segundo conjunto de muestras de referencia vecinas incluye muestras de referencia vecinas en el primer conjunto de muestras de referencia vecinas excepto las K muestras de referencia. La decodificación de predicción se realiza en el bloque de codificación de acuerdo con el segundo conjunto de muestras de referencia vecinas.
