Abstract

Un método para decodificar un flujo de bits de video. El flujo de bits comprende datos codificados para al menos una imagen, y cada imagen comprende al menos un grupo de mosaicos. El método incluye analizar una bandera que especifica si la información de mosaico para una imagen codificada está presente en un conjunto de parámetros o en una cabecera de grupo de mosaicos. La información de mosaico indica qué mosaicos de la imagen se incluyen en un grupo de mosaicos. El método analiza la información de mosaico desde el conjunto de parámetros o la cabecera de grupos de mosaicos con base en la bandera. El método obtiene los datos decodificados de la imagen codificada con base en la información de mosaico.
