Abstract
Un método de decodificación de datos de video, que comprende: recibir, desde la corriente de bits, datos de video correspondientes a un bloque codificado en modo no-omitir; determinar un conjunto de parámetros asociado con el bloque codificado en modo no-omitir; si el conjunto de parámetros satisface una primera condición, recuperar un primer elemento de sintaxis de la corriente de bits; si el conjunto de parámetros satisface una segunda condición, recuperar un segundo elemento de sintaxis de la corriente de bits; si el conjunto de parámetros satisface una tercera condición, recuperar un tercer elemento de sintaxis de la corriente de bits; decodificar los datos de video correspondientes al bloque codificado en modo no-omitir utilizando modo paleta cuando el primer elemento de sintaxis y el tercer elemento de sintaxis tienen el primer valor; decodificar los datos de video utilizando modo de intra predicción cuando el primer elemento de sintaxis tiene el primer valor y el tercer elemento de sintaxis tiene un segundo valor; y decodificar los datos de video utilizando modo de inter predicción cuando el primer elemento de sintaxis tiene el segundo valor.
