Abstract
Un método de decodificación de video realizado por un aparato de decodificación de conformidad con la presente descripción incluye derivar uno de una pluralidad de modo de predicción del modelo lineal de componentes cruzados (CCLM) como un modo de predicción CCLM del bloque de croma actual, derivar un número de muestra de muestras de croma vecinas del bloque de croma actual con base en el modo de predicción CCLM del bloque de croma actual, un tamaño del bloque de croma actual y un valor específico; derivar las muestras de croma vecinas del número de muestra, calcular los parámetros de CCLM basados en las muestras de croma vecinas y las muestras de luma vecinas muestreadas hacia abajo, derivar las muestras de predicción para el bloque de croma actual con base en los parámetros de CCLM y las muestras de luma muestreadas hacia abajo y generar muestras reconstruidas para el bloque de croma actual con base en las muestras de predicción, en donde el valor específico se deriva como 2.
