Abstract

Un aparato configurado para codificar información de video que incluye una unidad de almacenamiento y un procesador en comunicación con la unidad de almacenamiento. La unidad de almacenamiento está configurada para almacenar información de video asociada con una primera capa de video y una segunda capa de video. El procesador está configurado para procesar una primera instancia de un conjunto de parámetros en un flujo de bits, en donde la primera instancia del conjunto de parámetros comprende una primera indicación de que la primera capa de video y la segunda capa de video pueden utilizar el conjunto de parámetros, y procesar una segunda instancia del conjunto de parámetros en el flujo de bits, en donde la segunda instancia del conjunto de parámetros comprende una segunda indicación: (1) de que la segunda capa de video puede utilizar el conjunto de parámetros, y (2) de que la primera capa de video no puede utilizar el conjunto de parámetros. El procesador puede codificar o decodificar la información de video.
