Abstract

Un codificador de video genera una secuencia de elementos de sintaxis de desplazamiento adaptativo de muestras (SAO) para un bloque de árboles de codificación. Los elementos de sintaxis de SAO incluyen bins codificados por codificación aritmética binaria adaptativa por contexto regular (CABAC) regular para un componente de color y bins codificados por bypass para el componente de color. Ninguno de los bins codificados por bypass está entre dos de los bins codificados por CABAC regular en la secuencia. El codificador de video utiliza CABAC regular para codificar los bins codificados por CABAC regular y utiliza codificación por bypass para codificar los bins codificados por bypass. El codificador de video da salida a los elementos de sintaxis de SAO en una corriente de datos. Un decodificador de video recibe la corriente de bits, utiliza CABAC regular para decodificar los bins codificados por CABAC regular, utiliza codificación por bypass para decodificar los bins codificados por bypass, y modifica una imagen reconstruida con base en los elementos de sintaxis de SAO.
