Abstract
Las modalidades particulares de la presente invención pueden eliminar una comprobación de condición en la semántica para comprobar un indicador de datos de alta precisión. Esto simplifica la semántica utilizada en el proceso de codificación y decodificación. En este caso, incluso si el indicador de datos de alta precisión no está establecido, el valor del elemento de sintaxis de predicción ponderada se establece por la variable BitDepth. Sin embargo, incluso si BitDepth no considera datos de alta precisión, tales como 8 bits, el rango para el elemento de sintaxis de predicción ponderada es todavía el mismo que el valor fijo. Por ejemplo, los elementos de sintaxis luma_offset_10[i], luma_offset_11[i], delta_chroma_offset_10[i] [j], y delta_chroma_offset_11[i] [j] utilizan la variable BitDepth como se describe anteriormente si el indicador extended_precision_proce ssing_flag está activado y desactivado para indicar si la profundidad de bits está por encima de un umbral.
