Abstract

Un codificador para codificación híbrida de video, el codificador para proporcionar una representación codificada de una secuencia de video con base en un contenido de video de entrada, y el codificador configurado para: determinar uno o más elementos de sintaxis relacionados con una porción de la secuencia de video; seleccionar un esquema de procesamiento que se va a aplicar a la porción de la secuencia de video con base en una propiedad descrita por en el uno o más elementos de sintaxis, el esquema de procesamiento para obtener una muestra para una predicción compensada por movimiento en una ubicación fraccionaria y/o entera dentro de la porción de la secuencia de video; codificar un índice que indica el esquema de procesamiento seleccionado de modo que un valor de índice codificado dado representa diferentes esquemas de procesamiento dependiendo de la propiedad descrita por el uno o más elementos de sintaxis; y proporcionar, como la representación codificada de la secuencia de video, un flujo de bits que comprende el uno o más elementos de sintaxis y el índice codificado.
