Abstract

Un decodificador de video puede ser configurado para decodificar un primer valor representativo de una diferencia entre un valor de bits más significativos (MSBs) de base de un valor de recuento del orden de la imagen (POC) de una imagen corriente de datos de video y un primer valor de MSBs de un primer valor de POC de una primera imagen de referencia de largo plazo de los datos de video, decodificar un segundo valor representativo de una diferencia entre un segundo valor de MSBs de un segundo valor de POC de una segunda imagen de referencia de largo plazo de los datos de vídeo y el primer valor D MSBs, en donde el primer valor de POC y el segundo valor de POC tienen diferentes valores de bits significativos mínimos, y decodificar al menos una parte de una imagen corriente de los datos de video con relación al menos a una de la primera imagen de referencia de largo plazo y la segunda imagen de referencia de largo plazo.
